Overview
I'll answer the first question right off: yes, Axiom is one of those internet-only speaker companies. They're based in Canada. Like other Canadian speaker makers (PSB for example), Axiom has access to the National Research Institute. This well-equipped lab provides the best in test equipment to help manufacturers design the best possible products. I first learned of Axiom by reading reviews on the Audioholics website. I spent a lot of time over the past 6 months researching and listening to many brands of speakers. As a classical music lover, accuracy was of paramount importance to me. Axiom is one of the few companies that publishes detailed graphs of all their models online. I was also fortunate to find a local man who had the exact setup I was considering in his theater. After spending an afternoon spinning CDs and DVDs on his excellent setup, I made my decision. I placed my order online and 2 weeks later, the speakers showed up from DHL. All pieces were in perfect condition. Packaging was quite robust and secure. Axiom has a 30-day refund policy if you wish to return the speakers for any reason. They also cover any damage incurred in shipping. In fact, the man who demoed his speakers for me said they replaced a surround speaker he had damaged himself at no charge! All Axiom products carry a 5-year warranty. The system consists of 2 M60 tower speakers, 37" tall, driven by 2 6.5" aluminum woofers, a 5.25" aluminum midrange and a 1" aluminum dome tweeter. There are 2 ports on the back and one on the front. The 27" wide VP150 center channel uses 3 of the same 5.25" midranges and 2 of the same 1" tweeters. They are arranged in a TMMMT layout. This is unusual compared to other center channel speakers but there are definite benefits which I will talk about later. It is a sealed design. The QS8 surrounds are a sealed quad-pole design employing upward and downward firing 5.25" midranges and 2 1" tweeters arrayed at a 45-degree angle. The EP350 subwoofer employs a front-firing 12" aluminum driver and 200-watt amplifier. It is front ported.
Setup
My room is a bit unusual in that I have the couch and the TV in opposite corners. I placed the 37" tall M60 towers on a low TV bench I built myself. This placed the tweeters about 4" above ear level. For movie and TV sound, this is not a problem. For music, I would like to have the tweeters lower. I plan to solve this problem by building a seperate media room in an unused bedroom. More on my future mancave plans soon, stay tuned! Anyway, back to reality. I placed the center channel in a box I have suspended over my 50" TV. The sub was placed to the side firing at the seating area. The surrounds were wall-mounted. They are far from ideally placed but more on that later. All speakers were wired with 12-gauge cable and compression-style banana plugs from Bluejeans Cable. The mains were bi-amped. The sub was connected with a high-quality Belden cable also from Bluejeans. Crossovers were set at 60hz for the mains, 100hz for the center and 110hz for the surrounds. Channel levels were set with my trusty Radio Shack SPL meter. I did go +2db on the center and -2db on the sub after watching several movies.
Listening
Since the bulk of my listening is movies, I concentrated on that for the first few weeks. Let me tell you, if you haven't had a quality sound system for movie watching before, you don't know what you're missing! Even this system, which is far from expensive, blows away any movie theater I've ever been in. Mind you, most movie theaters are not calibrated properly at all. Often, subs or dialog channels are missing or set too low or too high. The last movie I saw in a theater, Harry Potter and the Order of the Phoenix, was painful to sit through. The dialog was OK but the mains and subs were so loud they approached distortion. I was physically exhausted when I left the theater. With a quality home theater system such as the Axiom Epic 60, you can finally hear a movie soundtrack the way it was meant to be heard in all its detail and ambience. And as my room is far from ideal, I can only imagine how much better it will be in a properly sound-treated room. (Mancave, more to come!) The center channel's unusual design placing the tweeters on the ends, really came to the fore. The sound field for dialog was far wider than traditional centers that place the tweeter in the middle. Plus, the Axiom's tweeters are less affected by the output of the midranges since they are only bordered on one side by other drivers. The surrounds as I said before, are very forgiving of placement. THX spec calls for surrounds mounted on the sides of the seating area, above ear level. Mine are to the side and to the rear. They are also mounted at 90-degrees to one another. Even with this huge compromise, the surround envelope is superb. Panning effects really do make you jump and the sound field is truly 3-dimensional. My favorite track so far is the movie Pan's Labyrinth. The scenes during rainstorms and gunbattles are just incredible. If you watch this movie, be sure to engage the DTS track, it's a little beefier.
Conclusion
This system cost me just over $2500 delivered. Coupled with the excellent Denon AVR3806 receiver and DVD 2930CI disc player, my in-home theater experience has improved by a huge factor. These are truly long-term speakers. Receivers and disc players are in a constant state of flux but good loudspeakers can last a lifetime. Unless I have to fill a significantly bigger space with sound, I can't imagine a better matched system. Axiom does have a larger tower model and 2 more sub upgrades should I feel the need, but I don't! My next upgrade will be the Mancave. I plan to buy another identical system from Axiom and install it in a dedicated, acoustically treated room. Stay tuned for that as I plan to document the entire process of building this room. Thanks for reading and enjoy the view!

Denon AVR-3806 Review
A few months ago I was finally able to upgrade my audio system to something more worthy of my excellent Samsung DLP display. I had muddled through for about 2 years with *gasp* a Home Theater in a Box from Sony. This system wasn't total crap but since installing the new gear, it's now gracing a landfill. For years I read the advice on various websites saying you should spend at least as much or more on audio as you do on video. OK but that's really hard to do. Of course you want the rockin' display with the most pixels, the biggest screen, you know the drill. It's what guys do. Well after installing this receiver and a 5.1 speaker setup from Axiom Audio, I can see the importance of this advice. Speaking of Axiom, I'll review the speakers and sub (M60s, VP150, QS8 and EP350) next week.
I purchased the receiver as well as a Denon DVD 2930CI from Crutchfield. You can read my review of the DVD player here. I highly recommend Crutchfield as a dealer. Their customer service is outstanding. The electronics arrived in a few days double boxed with generous amounts of peanuts. There was absolutely no damage to the Denon cartons. Crutchfield has a generous return policy and excellent support.
Setting up the unit was fairly straightforward. I'll tell you right now, the manual is terrible. The important information is there but you have to look for it. My advice with any Denon product: read the manual thoroughly before you install. This receiver like most modern multi-channel AVRs has many many options and features. You owe it to yourself to explore everything beforehand so you can get maximum performance from your gear. My main tower speakers are bi-amp capable so I wired them up as such, making sure to remove the jumper between the 2 pairs of binding posts. It doesn't matter which amp powers which drivers. Enter the setup menu and set the surround back amps to power the mains. After setting delays for the various speaker distances, I pulled out my trusty Radio Shack SPL meter to set levels. Using the test tones, I set levels for all channels to a reference volume of 80dB. I set the bass management as follows: front speakers set to small, 60hz crossover, center set to small, 100hz crossover, surrounds set to small, 110hz crossover. This gave the flattest frequency response when measuring frequency sweeps from the Digital Video Essentials audio tests. The only change I made after the fact was dropping the sub 3db. The Radio Shack meter is less accurate at low frequencies so this was as expected. Convenience features are all there such as auto-detect of audio track types, renaming of inputs and assignment of digital inputs. You might notice I've said nothing about the Audyssey auto calibration feature of this receiver. I actually bought this particular unit because of that function. I have every intention of at least trying the room correction in the future. I've just been so amazed and pleased with the sound the way it is, I haven't actually tried it out yet! My room is a bit challenging as well. I live on a fairly busy road. It would be nearly impossible to run the auto setup without a car driving by during the process. Perhaps if I did it late at night... If at some point I engage the Audyssey function, I will post an article about it.
Once all options were set, I checked my Denon Link connection from the DVD2930CI and fired up Casino Royale. Unfortunately, I heard nothing. OK, check connections, check setup, check DVD player (which I had already been using with my old audio setup). There was no light for Denon link evident on the player's front panel, hmm. I pulled out a generic CAT5 cable I had in my office and replaced the Denon cable that had shipped with my DVD player. Guess what? It worked just fine. Swell, Denon's supplied cable (which costs $45 by the way) was a dud and my free CAT5 cable that a friend made up for me worked perfectly. I had wondered if Denon Link was standard CAT5 and now I had my answer. If you want to install your player more than 6 feet from your receiver, you can with regular CAT5 for a few cents a foot. You do want the Denon Link by the way because it will support Direct Stream Digital transmission from SACDs. There is no other player in this price range that will do this. I believe the Oppo players will output PCM over HDMI from SACDs but not DSD. (was that a geeky sentence or what?) All other SACD players require you to use the multi-channel analog outputs. I also recommend using the IR in/out jacks if you have either IR blasters or some type of RF receiver for your remote. It beats sticking those pesky IR emitters to the front of your gear. In fact, I discovered the IR jack on my Scientific Atlanta 8300HD cable DVR actually works! I now have an IR emitter only on my TV. This is a much cleaner-looking and reliable way to control your components.
Sound quality? Let's just say... holy $@#&! The opening scene in Casino Royale starts with a guy riding up an elevator. The LFE effects are simply amazing. Then as he is confronted by James Bond, the scene flashes back to a fight in a bathroom. The bodies slamming through toilet stalls and other high-impact effects are simply breathtaking. Later during the now-famous chase scene, Bond drives a front-loader through a fence and a pile of iron pipe. The slam of this effect simply knocked my socks off! This is only the first day mind you. I have had this system in place for almost 3 months now and I can say I've never enjoyed movies and TV more. Even broadcast content is hugely improved. By default, this receiver will use Dolby Pro Logic II or DTS Neo6 to pipe all soundtracks into 5.1. This is done very well as you don't really notice the extra channels unless you switch back to straight 2 channel listening. My advice, let the DSPs do their thing, they work really well.
Music listening is equally amazing. For this, I engage the Denon's PureDirect mode. Even though the manual says this is only for analog sources, it still works with anything coming over the Denon Link connection. There was a small but noticeable improvement in the sound stage and the overall transparency of the music. (if you play Redbook CDs, they will play 2-channel whether you use PureDirect or not) I am strictly a classical buff so it's really easy to hear even the subtlest changes when you're trying new gear. I used SACDs of the San Francisco Symphony playing Mahler's 5th Symphony and the Kirov Orchestra playing Shostakovich's 5th and 9th Symphonies. I love multi-channel music and this setup really shone in this capacity. I'll expand on that more in next week's Axiom speaker review.
I believe this model is now being replaced by the AVR3808CI. From my research, it seems to the be the same receiver with the addition of HDMI 1.3a and decoding of Dolby TrueHD and DTS HD Master Audio. If these formats are not a factor, the 3806 is $300 cheaper so grab one while you can. I can tell you I am extremely happy with this unit and plan to use it for the forseeable future.

Panasonic TH50-PZ700U Calibration
I had an opportunity this past week to calibrate this latest Panasonic plasma. The PZ700U is 1080p with 2 HDMI inputs and a slot for an SD memory card to display photos. This display is not only one of the best plasma panels available today, it is also by far the best value. The only brand at this level is the Pioneer Elite line and you'll pay more than double the price for the same screen size.
There are 4 picture modes available, Standard, Vivid, Cinema and Custom. Only the Custom setting allows different settings per input. Selecting the Warm color temp got me within striking distance of D65. One interesting thing I learned concerned video noise reduction. There are 3 controls that address noise reduction and none of them seemed to affect the image at all. I was viewing 1080i multi-burst patterns and even though the 1-pixel pattern was rendered perfectly, I could see just a bit of noise around it. I finally removed the noise by turning up the Sharpness a few clicks from off. In fact, the Sharpness control at full blast didn't introduce any ringing in the image. My conclusion is that Sharpness on this TV affects noise and not edge enhancement. Another factor is the HDSize control. There are 2 options. Number 2 combined with Normal Aspect will give a 1:1 pixel map. The first option introduces about 3% overscan which is in spec but it breaks up the 1 pixel multi-burst. Bottom line, the sharpest and cleanest image comes in the 1:1 pixel mode.
Grayscale tracking showed a Delta C* error of 5-13 before calibration and under 1 after adjustments were made in service. I was also able to improve gamma and black levels by working the sub-brightness adjustment. I noticed when adjusting Brightness in the user menu that there would be a certain point where the gamma curve would change visibly on one side or the other of a particular number. Just below this point was the sweet spot for the final Brightness setting. After exiting service, I loaded a few Blu-Ray titles into the client's PS3 for some real content analysis. The first thing we noticed is there was still some downward room to be had in black levels. I settled on another 3 clicks lower on both the PS3 and the SA8300HD cable box sources. Like the majority of consumer displays, the black levels float somewhat depending on the average light level of the image. The adjustments made in service greatly reduced this tendency. For example; before calibration the darkest Pluge pattern would actually change after a few seconds. The lighter bar would at first be visible then disappear. After calibration, the pattern remained stable. The change in different light output levels also had less of an effect on black level. Even though this set is decent before calibration, this improvement alone is worth doing a full calibration.
The color-related aspects of the picture were excellent all around. Primaries are dead on for blue and slightly over-saturated for red and green. This is not visible in content. A slight lowering of the Color control aligned the decoder fairly well. Using my Progressive Labs CA6X allowed me to adjust the Tint to correct secondary color errors with respect to the measured primaries. This is much more accurate than using filters. Filters are only useful if they match the displays actual primaries and this is quite rare.
In conclusion, I would rate this as one of the finest HDTVs I have calibrated to date. It's the closest in dynamic range and clarity to the legendary Sony XBR960 CRT, my benchmark. Given the amazing price point of this TV (around $2500), there is no better value to be had, period. There is certainly no 50-inch LCD of any decent quality that sells for as little. And I have yet to encounter an LCD that can reproduce the blacks this TV can. I was so impressed with this display that I'll be adding one to my own theater in the coming months.

Logitech Harmony 890 Remote Control Review
I purchased the Harmony 890 a few months ago after programming one for a client. I was impressed with its ease of setup. I was especially interested in its Smart State feature that remembers the input and power states of your components. This is very helpful when a ccomponent doesn't support discreet commands for power and input. Many products lack discreet code support, most notably cable and satellite boxes.
The reason I haven't written about this product until now is I wanted to give myself time to thoroughly learn all its secrets before forming an opinion. The truth is, it's easy to do a basic setup but troubleshooting is less than intuitive. You begin by installing the included CD to your computer. You can use the front end software provided or log in via the Logitech website. Either way, you have to install the CD. The web front end is much faster however. Use the CD to create your account, then log in from the Harmony website. The software runs through a setup wizard to configure the remote. Logitech's IR code database is the largest in the business, over 170,000 components. In the unlikely event you have something that's not there, you can learn the codes from the factory remote. The wizard walks you through Activity setup where you program how things are to be turned on and set for different functions like Watch TV, Watch DVD, Listen to CDs, etcetera. You can also create custom buttons for each activity with labels shown in the LCD screen. There are 8 buttons available and multiple screens if you have more than 8 custom buttons. You can also set any hard button on the remote for any function from any component in the activity. Once you've programmed everything, it's time to update the remote via USB. Here's where I have a major complaint. The 890 includes a Remote Extender which supports RF control and sends the IR codes to the components via stick-on emitters. Every time you update the remote, you also have to update the extender. You can't have it plugged in the wall when you do this. This is a colossal pain especially when first programming since you'll want to tweak your setup at least a few times.
Once I had things working the way I wanted, the Harmony worked well for a few weeks. Then I started having trouble with Activity startup. Components would not always turn on or switch to the right input. This seemed to be random. It's like each component would take its turn not coming on. One positive here is the remote's Help key. If something unexpected happens, press help and answer the questions on the remote's screen. Usually, it will fix itself and you'll be back in business. To address this, I adjusted the various delays for each component. You can adjust the power on delay, input delay, inter-key delay and inter-device delay. Tweaking the inter-device delay seemed to fix the problem although it still happens occasionally.
Another major issue I have with this product is the ever-changing software. Logitech frequently updates both the front-end software and the remote firmware. Usually this results in some problems being fixed, new problems being created, some features added and some features removed. For several weeks, the Favorite Channel feature was disabled for no apparent reason. I can't imagine why Logitech can't stabilize this package and stop messing with it.
The bottom line with this product: for the price, it can't be beat. No other universal remote offers this level of functionality for less than $300. I like the physical design. I like the software interface. I don't like the random and unexpected glitches. I don't like the frequent software updates. I don't like having to unplug the extender every time I want to update. I want to love this remote. If Logitech would stop messing with it, I think I could. I do plan to keep using it. I can't justify dropping 3 or 4 times the money on something better.

Denon DVD-2930CI Review
I spend so much time helping clients with their cool AV toys that I sometimes forget to satisfy my own needs for nifty new gear. To alleviate this, I've recently made a major upgrade to my theater: a shiny new Denon 2930CI DVD player! I had been using a no frills progressive-scan Sony player for about a year or so while wondering what to do about new formats and the dropping price of quality video processing. When Denon announced the inclusion of the HQV Reon chip in their new player, I knew where my AV dollars would be going next. Thanks to Crutchfield, I've now had this player sitting in my rack for about 2 months.
As with all Denon products, this player is built like a tank. It weighs 17 pounds and stands just over 4 inches tall. It occupies a full 17 inches of rack width and 16 inches of depth. I connected it to my Samsung 50-inch DLP with a Bluejeans Cable HDMI cable. I'm currently running the audio through an optical cable to a Sony receiver but soon I will be utilizing the Denon Link connection with a Denon AVR-3806. I set the HDMI format to RGB and 720p to match the native resolution of my display.
My first order of business was to pop in the GetGray calibration DVD and view a few test patterns. Since my Samsung TVs color management settings and white point (adjusted in service) are global, my primaries, secondaries and grayscale tracking were already calibrated. It’s good to know I can get consistent results from HDMI or component inputs on this set. I tweaked the black and white level settings to resolve the pluge and ramps patterns properly. Since this player offers image positioning controls, I centered the picture using an overscan pattern.
I couldn't wait a moment longer to run through the HQV torture-test disc so in it went. Needless to say, it aced every test. I honestly don't know what the differences are between the Reon and Realta chips are (the Realta is found in the Denon DVD-3930CI and 5910 players), but it would seem that for a mere $849, I had achieved video processing quality previously found only in players costing far more.
Moving on to actual content: I picked some of my worst quality DVDs to try like Buffy the Vampire Slayer, and Babylon 5. No, they didn't look like HD but dynamic range was hugely improved. There was absolutely no trace of jaggies anywhere! I really looked hard too! Once I put in high-quality DVDs like Lost or James Bond Ultimate Edition the image was simply stunning. It truly approached a high-quality HD feed. In fact, I would rate it higher than some HD content I've seen on DirectTV. Color and dynamic range are simply in a new league with this player. And did I mention the sound? My current speaker system is far from state-of-the-art and I heard an immediate difference. Imaging and clarity were much improved. I can't wait to run some SACDs through this thing! That will have to wait until I've installed my new Axiom speaker system. Stay tuned for that in about a month. One footnote on Denon Link: besides the HQV chip, Denon Link is the other big reason to choose this player. This is the only non-Sony product that I know of that will play SACDs over an all-digital connection. Paired with Denon's AVR3806 receiver, this player will send all sound formats digitally. My system now has no analog sound interconnects whatsoever!
I know many people are waiting to see the results of the format war before buying a new disc player. I almost did myself. I finally reasoned that eventually, there would be players that could read both formats as well as standard DVDs and all types of music CDs. There has already been a press release about a decoder chip that reads both HD and BluRay and LG Electronics is currently advertising a player that incorporates it. I feel it's only a matter of time before Denon releases players that read every currently available optical disc with HQV processing and SACD over Denon Link. When that happens, I'll be upgrading. For now, I am thrilled with my 2930CI. To beat this level of image and sound quality, you would have to spend at least three times as much money. There will be support and demand for standard DVD for years to come. Why not enjoy them with the best player you can afford?

Sony KDL-40V2500 LCD Calibration
This is Sony's least expensive 1080p LCD TV. It retails for $500 less than the next model up XBR. The extra dough gets you another HDMI input (3 versus 2) and a few more image enhancement features. Otherwise, it's the same panel and backlight. The 40-inch TV I calibrated is perfect for a bedroom or small den. With the high-resolution image, the ideal viewing distance is about 6-7 feet.
After beginning with the basic pluge patterns to set brightness and contrast, I then turned to the backlight control. With all the LCDs I've done so far, the best black level detail is to be found with the backlight turned to the Minimum setting. There is still plenty of light at the high end and daytime viewing is fine. In fact, I calibrated this panel in a fairly bright room with a large side window. I always recommend against using the Day/Night sensor. This feature changes the backlight levels depending on the ambient light. Sounds great in theory but in practice, the change is far too drastic resulting in very washed out blacks.
On to the service menu: I got a nice surprise here. Sony service menus are usually a collection of binary codes and very terse abbreviations. I always go in with reams of notes from my colleagues. This set is too new however so I didn't have quite as much backup as I would have liked. Wouldn't you know it, Sony decided to include a clear, graphical menu with clearly labeled controls for grayscale, image positioning and other features. I was able to achieve a Delta C* under 1.0 from 30 to 90 IRE with humps to 1.6 at 20 and 100 IRE. This is an extremely accurate grayscale tracking result. These settings were global for all inputs.
Returning to the user menu, color controls were left at defaults as the gamut and decoding were quite good. The green primary read as oversaturated but this was not evident in actual content. The best gamma (2.1) was achieved with the gamma control turned off. All other Advanced Video menu items were turned off except Black Corrector which was left at Low. The TV resolved a 1080i multi-burst pattern perfectly without any help from image enhancement settings.
The resulting image was very smooth and life-like. Details in DVDs played on the client's Oppo were crisp in both bright and dark scenes. Color and clarity from the 8300HD cable box were excellent on high-quality feeds like PBS and INDHD. All in all, the set was quite responsive to ISF calibration. It responded favorably and rewarded my efforts with an extremely accurate and clear picture. If you're looking to save a bit of cash over an XBR, the V2500 is the TV for you.

Sony KDL-46XBR2 LCD Panel Calibration
With the recent price drops on LCD panels, more and more clients are requesting calibration of these sexy thin TVs. Even though they've been around a few years now, it's still cool to see a TV that's only 3 or 4 inches thick. This calibration was for one of Sony's top-of-the-line new panels the 1080p KDL-46XBR2. This TV has all the necessary calibration controls in the user menu to include grayscale, gamma and several interesting noise-reduction controls. Since my client was switching his satellite box and DVD player (a superb Marantz DV-9600) through a receiver, I only had to calibrate the HDMI inputs on the TV.
Most Sony TVs have a DRC palette control which only works for 480i signals. This TV allows the DRC controls to work on all scan rates. I was able to fully resolve the multi-burst patterns with the DRC controls and use less of the traditional edge-enhancements. The end result was a super-clean noise-free image from all sources. Of course, I set the satellite box to always output 1080i and the DVD to output 1080p. By the way, if you spend enough money on an upconverting DVD player, it really does approach HD quality. It's not quite there but it's darn close.
The color and tint controls required no adjustment so I moved on to grayscale. I got the tracking within 100k of D65, excellent performance. I spent a lot of time checking each gamma setting and finally settled on medium. This coupled with reducing the backlight to its minimum setting gave me deep, detailed blacks and a gamma curve of 1.93. By the way, this panel has a nearly perfect color gamut. Primaries and secondaries lined up beautifully right out of the box. I'm glad to see a TV that makes color accuracy a priority over excess light output and over-saturated colors.
Needless to say, the resulting image was stunning. This is by far the best LCD panel I've worked on to date. It seems like I've had quite the rush on Sony calibrations lately but they really do make some fine hardware. With the amount of control available, this is one of the more ISF-friendly TVs out there. It's a pleasure to achieve such good results without burning incense and chanting to the video gods for guidance. As an added bonus, my client had me calibrate his XBR960 CRT. I've covered this set in a previous post but I'll say it again, this is the last of the truly great CRT TVs. It's hard to beat its rock-solid image with accurate color, excellent geometry and of course dynamite blacks. Two excellent TVs to calibrate in one house, it was a video geeks dream come true!
Hitachi 51F510 Calibration
CRT-based displays are a dying breed. This is unfortunate because they still do some things better than even the best fixed-pixel TVs. Principal of these is blacks. A good CRT can render the smoothest and blackest blacks unmatched by even the best plasmas. You can't beat a display that can turn off areas of the image for a true black. Even plasmas must send a little current to every pixel to maintain response times. CRT does not have this limitation. After spending about 6 hours with a Hitachi 51F510, I can see why some people are hanging on to their older sets.
This TV was about 3 years old and had been well-cared for by its owner. He had removed the reflective screen cover, which not only causes major glare but it creates a color shift as well. He also lined the interior of the TV with light-absorbing Duvetyne. This dustless fabric prevents any internal reflections in a rear-pro cabinet and in some cases can really improve black level detail. He called me in to not only calibrate the set but also to work on the geometry and convergence.
The Hitachi has all the necessary controls in the Service Menu to adjust overscan and centering. I touched this up first then proceeded to the Convergence Menu. Rather than using the Magic Focus which sets the convergence hands-off, I did the 117-point adjustment with the TVs internal grid pattern. I worked out from center aligning red and blue to green. After 2 laps around the screen, I was done and the grid was tack-sharp.
Calibration followed with settings in both the User and Service Menus. There is full color management and color decoder adjustment available with color isolation. I was able to tame the red push pretty well and get the primaries right on spec. After adjusting the grayscale in the service menu, I touched up the color decoder again and I was finished. A long process but well worth it. This client had hoped to get some more life out of this TV rather than buy a new one and I was able to help him do that. CRTs do require a bit more work but the results are well worth the effort. I expect he'll be hanging on to this set for quite awhile longer!

James Bond Ultimate Edition DVD Sets
I have always been a big Bond fan. I owned most of the movies on tape and watched them until they wore out. When I finally went to upgrade to DVD versions, I discovered that all the movies were out of print except Die Another Day. What a treat it was when I found out about the newly-remastered Ultimate Editions. All 20 movies in 4 sets for about $60 each on Amazon. I just received the first 2 volumes (3 & 4 ship December 12).
Today I watched Diamonds Are Forever. These DVDs are advertised as 4k Lowry Digital frame-by-frame transfers. This means the film is scanned at 4000 lines of vertical resolution. They are then down-rezzed to the standard 480i DVD resolution. The result is quite simply the best DVD I have ever seen. I just couldn't believe I was watching a 35-year old movie! Not only was the color and dynamic range stunning, the clarity was razor-sharp as well. There wasn't even any film grain! When I see DVDs of this quality I have to ask myself: is there really a need for HD-DVD and BluRay when standard DVD has such potential? If more movies were mastered with this kind of care and precision, the world would simply be a better place.
Equal in quality to the images was the sound reproduction. All the movies have a remixed soundtrack done in Dolby Digital and DTS. The original films were monoaural and stereo. It's just incredible what can be done with such old material. I recently ordered a Denon DVD2930 and AVR3806 from Crutchfield. I can't wait to install these components and watch more of these Bond flicks. These discs have given me more than enough reason to watch all these wonderful movies again and again. Bond fans rejoice!

Sony KDL-40XBR LCD Panel Calibration
I recently had the pleasure of calibrating a 40-inch version of Sony's 720p LCD panel, XBR model. This set is a superb value for an LCD offering excellent image quality and adjustability for a reasonable price. As I've said in other posts, 1280x720 is still a lot of pixels and a properly calibrated 720p TV can look every bit as good as a 1080p TV for less money.
This panel has an excellent contrast ratio. I measured 910:1 on a 4x4 ANSI checkerboard pattern after calibration! This is the highest ratio I've recorded to date. Unlike other Sony TVs I've calibrated, some of the options in the Advanced Video menu actually improved the image. I left Live Color on (Low setting) and chose the Wide Color Space. Usually, these options put the primaries way outside spec but in this case, the primaries weren't too far off. It was then on to the service menu to adjust grayscale. My first pass had the tracking pretty good but Delta C was not to my liking. After more tweaks, I got Delta C under 1.0 from 20 to 100 IRE. I was very happy with this. Dark scene quality took a big jump despite having no control over the gamma curve. I couldn't quite get it to 2.2. I finished by setting the backlight control, which is independent of the brightness and contrast controls. I lowered it quite a bit on the DVD input, down to 3.
The final result was quite improved especially showing dark content. Black levels are a weakness of any LCD but this panel looked quite good in that regard. I strongly suggest some sort of bias lighting to improve the viewer's perception of black levels. This set was in a room where the panel had an open staircase behind it. This provided a bias light of sorts. If your panel is on a wall or stand, getting some 6500k lighting behind it will greatly improve image quality. Actually, this method works with any type of TV.
Another Sony TV successfully calibrated!

Samsung HL-R5067W calibration
The Samsung DLP rear-projection TVs are in the product category of "well-kept" secret. Why? Because they have the greatest potential for truly stunning picture quality. Even the HLR series which I'm writing about today, which has the fewest adjustments of all Samsung DLPs, will blow away nearly every other TV I've worked on when properly calibrated. This is a 720p model which is now discontinued. It has 2 component and 1 HDMI input. Picture out of the box is fair from a color standpoint. Banding and macroblocking are evident in both dark scenes and fine-gradient images like sky and hazy mountains. A few tweaks in the user menu will improve black and white levels immensly. The default contrast is set to mega-torch mode. A 100 IRE full-screen actually hurts the eyes.
As with all Samsung TVs, you have to go right to the service menu to perform your adjustments. The reason is all user menu settings are reset to defaults when you do this. Fortunately, everything you need is in there. I begin with the CCA menu. First a warning, don't try this at home! To use the CCA properly requires the use of a colorimeter to set the baseline for the light engine. Simply changing the target values will not adjust the color accurately. I worked in a totally darkened room to be sure of accurate measurements. After setting the baseline, I worked the targets until primaries and secondaries were nearly dead-on spec. Only red wouldn't quite hit the bullseye. I suspect I am being limited by the actual color wheel segment colors. After engaging WB_Spread to send the settings to all inputs, I moved on to grayscale. This is set for each input in the DNIe menu. Since the color management is so good, I barely needed any adjustment here. When I finished, I was within 100k of D65 from 20 to 100 IRE, superb performance. I only wish this display had an iris. I couldn't get a gamma better than 2.1. The curve tracks almost perfectly though with a slight rise from 20 to 60 IRE. Once service menu adjustments are complete, I exited to the user menu and made the final tweaks to black level, white level and sharpness. Since only color saturation was available, I increased that to compensate for the undersaturation of the red primary.
With calibration complete, I noticed an interesting phenomenon. Many people have complained that with the HLR series, you can't defeat the DNIe. To see if its effects were still degrading the picture, I turned on the demo mode. Surprise, surprise, both sides look the same! This is with sharpness set to 40 on the DVD input and 20 on the cable TV input. It seems that fixing the color inaccuracies and getting the gamma closer to 2.2 eliminates the negative effects of DNIe.
Based my experience to date, I would recommend a Samsung DLP over other rear-pro sets. With an ISF calibration, it simply won't be beat. As long as you aren't one of the 1% of people that see the rainbow effect, you won't be disappointed with a DLP and ISF calibration. Even with the wildly varying quality of standard-def content, the picture is simply incredible. With hi-def or a good DVD, you will be amazed. I can't wait to get my hands on one of the newer Samsung 1080p sets!
Enjoy!

Sony LCD Rear Projection, KDFEA10 Calibrations
I recently had the opportunity to calibrate 2 different Sony KDFEA10 LCD RP sets, a 50 inch and a 42 inch. These are excellent values for 720p HDTVs. They are discontinued now but many dealers still have them in stock. They have 2 component inputs and 1 HDMI input like other TVs of this type. Calibration is through the service menu and is global for all inputs. Grayscale can be set very precisely to track within 150k of D65. To adjust the color decoder, there is a "color axis" setting. This appears to rotate the gamut almost like a clock. There are about 50 different settings. I used the color analyzer to find the most accurate one. Once the grayscale and decoder is set, final tweaks are done with the iris controls. This varies the black level enough to affect the grayscale so I had to compromise to keep each input close to spec. In the end, I left the iris on its minimum setting for the component inputs and medium for HDMI. I also set different parameters for Black Corrector, Gamma and Advanced Iris to adjust for the grayscale shift through HDMI.
This TV was fairly difficult to work on because all the settings were interacting with each other. Luckily, the service and user menus are accessible at the same time. I went back and forth for quite awhile to get the results I wanted. I wound up with a great looking TV when I was finally done. I wish I could hide that awful Vivid picture mode. It's so bright and blue it's painful! Once you've become accustomed to a calibrated image, Vivid is downright offensive!
I still see these sets for sale at the big box stores. The prices are quite low. They're probably one of the best bargains for an HDTV right now. Even after adding the price of a calibration, you've still got a 50 inch HDTV for under $2000.

Sony XBR960 CRT Calibration
Last week, I had the priviledge of calibrating an Sony 34-inch XBR960 CRT. This is probably the last truly great CRT HDTV. It has been discontinued but there are still some deals out there. MSRP is around $1800 but they can be found for under $1000. The first thing I noticed is the excellent black level. Not only are the blacks really black but it was totally stable through the different APL Pluge patterns. I had superb notes on this TV's service menu so I dove right in. Grayscale is adjusted for the Neutral color temp at 1080i. Then you adjust offsets for the other scan rates and color temp presets. A complete set of decoder controls is also available. Once again, I was able to use my Progressive Labs analyzer instead of filters to really achieve accuracy. I also adjusted the image position and overscan. When I had finished, the gamma curve was a perfect 2.2, not 2.19 or 2.21 but 2.2! Grayscale tracked within 200k of D65 with all Delta C* points below 1.
Needless to say, the customer and I were very pleased. He is very proud of this set and it was my pleasure to calibrate it for peak performance. Even though CRT is nearly gone from the marketplace, there is still a large base of customers with quality sets that have yet to realize their full performance potential. I look forward to the next one.
Sound and Harmony remote setup
Last night, I completed work on a customers home theater system. After calibrating his Sony A2000 on a previous visit, I spent about 8 hours total wiring a receiver, DVD player, Tivo, VCR, Xbox into the TV and surround speaker system. The speakers are interesting, they're Definitive Technology BP-2000s. The mains and center have built-in 15 inch subs with their own amps. The remaining drivers have high, mid and low wire terminals as well. My customer was going for mega bass so I wired the left and right subs and bi-wired all three front speakers. We fired up Super Speedway. With the subs turned up to half it was an earthquake! He says, "I need more." I went to the point of distortion and backed off a bit. At this point, my ears hurt and his enormous leather sectional was shaking. He said, "that's the bass I've been waiting for!" He'd had these speakers for several years and never wired them correctly. Once I got his Denon AVR-5700 configured, it was armageddon in there!
I completed the job by setting up a Harmony 890 remote for him. This is a slick piece. Logitech's code base covers over 175,000 products. Take that URC! I had it up and running in about 2 hours. I'm going to get one of these for myself. It supports RF so you can put your rack in a closet or behind the couch if you want.
Bottom line: the customer was happy, I was happy, I had fun. It was my first time doing an entire system setup. From here on out, I'll have a price schedule for sound system and remote control setups. I know there are a lot of people out there that need help with these products. They're so capable and so complicated. Why spend thousands of dollars on technology and not get the maximum performance possible?

Followup work on Sony KD-S60A2000
I first calibrated this TV about 2 weeks ago. Nice set but the color tracking is not quite as good as the KD-SR60XBR1. It does have excellent black level stability and far less edge enhancement artifacts though. The image quality from a good source is excellent. I was able to tame the red push with a little tweaking of the hue control and my trusty Progressive Labs analyzer. My customer just installed the HR-250 Tivo. The quality from this feed is spotty. Some channels like HDNet look fantastic. Others are just soft. Here in NY, all HD channels are fed over the dish, not over the air. I think quality has suffered as a result.
I'm also doing an audio setup and remote control setup for this customer. He has an excellent Denon AVR-5700 and some impressive DefTech speakers with built-in amplified subs. The wiring is a bit unusual but I've got it figured out and I'll be finishing it up next week. I did a basic setup on a Harmony 890 remote. This is a very well designed piece. I'm going to add one to my home very soon. After going through about a 20-minute process on the internet, the remote was programmed with the basics. All I have to do is reconfigure a few screens on it and I'll be done.

Sony KDS-R60XBR1 Calibration
I've been wanting to do one of the Sony SXRDs for awhile and I just got my chance. Boy what a nice TV! It's quite a light cannon out of the box. It also adds major edge enhancement especially when scaling up DVD output from 480p. I put up the opening of Star Wars Episode I to see the text scrolling in the beginning. The letters had large white borders around them! The yellow color was almost completely covered. Needless to say, the sharpness was the first thing I worked on. I worked with this control and all the other enhancements available. I wound up turning everything off and dialing the sharpness down to almost the bottom. I could still resolve the 1080i pattern just fine without and extra video processing.
After setting the correct black and white levels, I moved on to the grayscale controls in the Advanced Video menu. I was able to achieve superb tracking (within 100k of D65) on both the component and HDMI inputs with a slightly better result on HDMI. The grayscale was so good, I barely had to touch the color and tint controls afterwards. The secondaries were almost perfectly aligned. Like other Sonys, this set did have a red push but it was easily tamed with a tweak of the hue control. My Progressive Labs analyzer makes it a breeze to get proper color and hue settings rather than using filters which are unreliable with displays other that CRT.
In the end, I increased the contrast ratio from 160:1 to 204:1 (measured with an ANSI checkerboard at 16 points on the screen). Color and grayscale were about as close to perfect as you could ask for. Super TV and even better with calibration.
Lost Season 2 DVD Review
I just got this set in the mail last Thursday and my wife and I have already watched 14 episodes! We're fans to put it mildly. There's no need to go into the specifics of the show, it's covered in a myriad of places on the internet. These DVDs are quite simply the best transfers I have ever seen! Of course, the original is shot in HD which helps. Honestly though, the difference between these DVDs and an HD broadcast is minimal. The sound is also top-notch. All scenes on the beach really show the surround effect with the wave noise enveloping the viewer. The balance of music, dialogue and sound effects is also superb. Dynamic range is excellent with no one element being either too loud or too soft.
From what I hear, these DVD sets can be found either online or in big-box stores for between $35 and $45. I say get 'em while they're hot! If you're even contemplating becoming a Lost fan, you won't be sorry!
