IntroThe DV-79AVi replaces the former flagship Elite DVD player, the DV-59AVi, which retailed for $1600, and it has a number of added features. Pioneer, like several of the other makers of both SACD-only and universal disc players, used to convert the DSD data of SACDs to PCM before outputting at the two or six-channel analog jacks and the i.LINK outputs. The 79AVi does not do that, retaining the DSD signal until conversion to analog ("SACD Direct"). The case is beautifully designed and quite sturdy, though not as solid and heavy as my Integra 10.5 (which retails for 2.5 times as much). Just about every possible connection option you would need is found on the rear panel of the 79AVi.
SetupI used Monster Cable component cables, not having any compatible HDMI gear on hand at the moment. The six-channel analog cable sets to and from my multichannel switcher for SACD & DVD-A were Harmonic Technology's Rainbow cables. Running the Elite thru my remote-controlled six-channel switcher allowed me to compare both CD and multichannel hi-res discs on the Elite with the Integra and the new Oppo DVD 970HD. (Other reviewers have been reporting poorer fidelity using the multichannel audio capability of the latest HDMI vs.six-channel analog connections.) I lacked equipment to interface with the i.LINK connections, also called IEEE1394 and FireWire. With HDMI the 79AVi offers two special video parameters: HDMI Color and HDMI Detail. There is a provision for SRS TruSurround, which creates a 5-channel-like surround effect from only two front speakers. Audio cables were mostly Kimber Kable, and I also used a Kimber AC cable. Prior to auditioning I ran the 79AVi on repeat with a couple different sampler discs - both SACD and standard - for several days. I also put the player on the carbon suspension blocks from Boston Audio Design. The 79AVi manual is 100 pages are very thorough. [The rest of my system involved: Sunfire Theater Grand IV AV preamp, Consonance M400 tube monoblocks, Von Schweikert VR-2s L & R with VR-1 center, Elite Pro-510HD RPTV.] The first step is to do the initial settings for the player using the on-screen Setup Navigator. The procedure is similar to most DVD players so I won't detail it here. I was surprised at the extensive picture quality settings possible. There are different options for plasma screens, for CRTs, an enhanced setting for animation, and so on. Also controls for white and black levels, gamma, hue, chroma etc. It would be well to ascertain what options you have already selected on your video display before changing any of the default settings on the 79AVi. The remote control, by the way, is not backlit but it is well laid out and quite easy to use. The most vital of its commands can be easily programmed into a universal remote such as the Harmony. DVD Video ViewingPioneer's Pure Cinema technology converts 24-frame film material to progressive 30 frames video rate to more closely match cinema picture quality. I have the settings on my Elite 53-inch CRT monitor optimized and usually merely set DVD players to interlaced output. However, since that display is becoming rather long in the tooth and the 79AVi is more recent, I thought there might have been improvements to Pure Cinema in the meantime. I therefore went into the Setup Navigator on the 79AVi to make sure Pure Cinema was turned off. It was not; the choices are a bit confusing, being labeled only that your display is either Compatible or Not Compatible. Fortunately, at the bottom with Not Compatible appeared a line of text saying "Outputs 525i interlaced signal from component out." That's what I wanted. Not being enough of a videophile to get out my video test discs, I just watched a few select scenes from two of the current feature film DVDs I was reviewing.Then I turned off the Pure Cinema option on the Elite display, which had been set at HQ - the highest setting. And I went back to Setup Navigator in the 79AVi and selected Compatible. There is an adjustment for the speed of the Pure Cinema treatment, and according to others more videophilic than myself the best setting for this is Slow. I watched the same excerpts on the two DVDs again. There was a noticeable improvement in depth, dimensionality and a more film-like appearance. So improvements have been made in the Pure Cinema technology, and I'll let the 79AVi do the processing after this rather than my aging display.The picture quality was brighter and somewhat more detailed than that from the much-pricier Integra 10.5, but the differences were subtle. It was also very similar to the Oppo player. While the 79DVi lacks some of the advanced video processing of the 59DVi, it does have 4:4:4 video upsampling and something called the Super-Fine Focus Filter, which increases the horizontal resolution to 540 lines. I found the video performance exemplary. Audio AuditioningIn general the sonics produced on all the various formats by the 79DVi paralleled in sound the qualities of the picture display. It was detailed and more forward and bright than either the Integra or Oppo universal DVD players, as well as my modified Sony CE775 SACD player. My first most telling A/B comparisons are always those with high quality standard 44.1 CDs. Some of the best universal players which excel in playback of all the other options sometimes fall down when it comes to standard CDs, although that has improved recently. I tried both the coaxial and optical connections and heard no difference between them. I used the Source Direct setting on my Sunfire AV center, which bypasses all digital processing and feeds the signal directly to the amps.I have several duplicate copies of standard CDs. Some have been tweaked with green pen or Cryo, but in such case both copies have been so treated so there is an identical match. The 79DVi was very close to the quality CD playback of the Integra, but a subtle refinement present with the Integra was missing. Piano music is one of my favorite test sources. The same solo selection of music of Lecouna had an increased brilliance on the 79DVi but the Integra supplied a bit more support and impact behind the notes. Solo instruments with orchestra tended to seem a bit closer physically with the 79DVi as opposed to the Integra. (Remember we're talking a 2.5 times more expensive player here!) I would say neither was right or wrong - just a personal taste matter.I next compared a number of three-channel SACDs, deciding to concentrate on the frontal soundstage playback rather than risking any confusion with the surround channels also in operation. I found SACD playback quality identical to the Integra uni player, while both the Oppo and Sony players were extremely close behind, making it difficult to pin down any differences with some of the discs. When I began the hi-res audio comparisons I noticed a slight enhancement when switching to the Integra from the Elite player. Then I saw that I had selected the Video Off feature on the Integra, which disconnects all the video circuitry to assure the purest audio signal. I had not selected the same option on the 79AVi. Also the 79AVi was originally sitting on its own feet directly on the shelf whereas the Integra was on the Boston Audio Design graphite blocks with weights on top. So I put a second set of the graphite blocks under the 79AVi and turned off - using the front panel button - the video circuitry. Actually, Elite calls this Pure Audio and when you push the button you get a blue LED to indicate you are now in Pure Audio. What was a surprise was that their iteration of this feature turns EVERYTHING off - including the front panel display! You no longer have any indication of what track you are on or the timing. Anyway, the tweaks were worth it because now the match of both SACD and DVD-A reproduction between the two players was just about identical.ConclusionThe DV-79AVi came thru with flying colors as the best flagship DVD player that Pioneer offers. It has all the features one could want and would be a good choice for any fan of the hi-res formats who currently struggles with switching between separate players for SACD and DVD-Audio. Although its performance with standard CDs is better than were many of the earlier SACD and universal players, it is still not up to the level of most of the CD-only decks retailing at the same price point. If your main interest is video DVDs or either of the two hi-res audio formats, or if you already have a high-quality separate CD-only player, the DV-79AVi should be seriously considered. It appears to be available at a street price considerably lower than the SRP listed. - John Sunier

Oppo DV-980H Universal DVD Player
Intro
This is the fourth universal player from Oppo and achieves new heights in both quality of audio playback and cost value. We reviewed in the past the DV-970HD, which is suggested for those using an external video processor with HDMI input and 720p/1080i resolution or smaller screen size. The DV-981HD (which we also reviewed) is slanted more toward the DVD movie fan with its DCDi Faroudja processing , whereas the 980H has enhanced audio playback circuitry, including DSD output over HDMI cable to AV receivers/processors with DSD decoding. (This may be the very first SACD player to offer that - only possible with v1.2a or 1.3 of HDMI.) The 981 is recommended for users with very large RPTVs or front projector setups. It also includes the best conversion between NTSC and PAL - although the other two models do play back PAL DVDs. Cross Color Separation, Inverse 1:1 pull down for PAL movies, noise reduction and TrueLife detail enhancement are offered only on the Model 981HD. A detailed comparison of all three current models is found on this Oppo website page.The appearance of the 980H is more stylish and attractive than the other two models. A useful new feature is the frontal display of the resolution you have selected: 480i, 480p, 720p, 1080i or 1080p. Though the video chipset does not include Faroudja processing, it effectively upconverts 480i sources to 1080p for display on 1080p-capable screens. It is especially recommended for larger DLP displays, which I have. There is also a USB input right on the front, which accepts a USB cable or a USB thumb drive directly. The display is very easy to set up, and accepts almost any video or still image files for showing on the big screen, including hi-res sources (which the other two units do not accept). It also features a variety of different wipes and dissolves for the slide show feature.

OPPO Digital HM-31 HDMI Switcher
IntroOppo Digital has been turning the universal disc-player market upside down with their award-winning yet inexpensive players. Now that HDMI has become the No. 1 digital AV connector in the home theater field, consumers are finding themselves with more and more component sources which demand HDMI inputs on their AV preamp-receiver, video processor/scaler or HDTV video display. Many units only have two inputs and even those with four are often not enough when one has different sources such as set-top box, DVR, DVD player, Blu-ray player, media server, video scaler, etc. An HDMI switcher is the solution, and Oppo now offers one.In & OutThe HM-31 has three HDMI inputs and one output - all v. 1.3 compliant. It is powered by an included small wall-wart and comes with a remote control. There is no on/off switch, as it is always powered up. There is a one of the popular new bright blue LED indicators to show which input is selected, and the power indication is red. On the right front of the unit is the input selector button.

Oppo DVD 970 HD Universal DVD Player
I ran into this product by accident. I was looking for a cheap universal DVD player for my bedroom stereo setup. I was hoping for the announced Pioneer DV 696 AV. I found out that they released that product in Europe but not America. So I did an Internet search for universal players and ran into an Oppo DVD universal player. I thought, “Oh no, not another el cheapo unknown manufacturer's product." I went to the web site www.oppodigital.com anyway. I looked at the specs and saw it did everything I needed a player to do, plus a lot more. I decided to order one for the bedroom system, figuring it would be good enough for that system. On their site they had a link to a video magazine which has run tests on well over 100 DVD players over the past years. The model preceding the 970 (model DV 971HD) had received the highest video score of any DVD player that they had tested. The number two tested player was a $3500 Denon model. It was amazing to see how poorly many of the highly regarded players performed. [In fact, of their 19 stringent tests of video capabilities on both HDMI & component outputs, the Oppo unit only failed 3. One recent $1000 universal player from a major manufacturer showed almost as many failed as passed in the same tests!...Ed.] The video testing site found the Model 971 to be actually better than the 970; that would be very scary. The DV971 is more of a strictly DVD player, has Faroudja processing and is $50 more. But it does not have HDMI output or play SACD/DVD-A. I found three good universal players that are out now. The Oppo 970 tested as well as the $2000 Onkyo DV-SP1000 and the $750 Denon DV 2910, and better than $370 Denon DV 1920. One player than looks promising is the Arcam DV 137 at $2000. It has the best chips I have seen in a DVD player and up-samples DVD to 1080p.

Oppo Digital DV-981HD Universal DVD Player
This is the third DVD player to come from Oppo in the space of a year or so, and it's quickly jumped to the top of the heap in many comparisons of players - and clearly not just for the very reasonable price. The U.S. office in Silicon Valley is an arm of a giant Asian electronics firm named BBK Electronics, which has been around a long time and whose output matches Sony and Panasonic.Video PlaybackWe reviewed the Oppo 970HD uni player back in July of last year and found it a terrific deal in a budget DVD/uni player. The DV-981HD retains most of the features of that player but builds on them in several areas, making the slight price increase more than fully justified, especially if your video display is 1080p capable. There seems to be much more noticeable improvement with most video upsampling vs. audio upsampling. The 970 only uprezzed to 720p, whereas the 981 carried it all the way to both 1080i and 1080p. The player incorporates uprezzing technology from leader in the field Faroudja and does offer further improvement in resolution with greater clarity and fewer noticeable artifacts. Faroudja's TrueLife sharpening filter is included but can be defeated if you wish. It is more likely you will want to defeat the other filter and processing options offering on the 981, unless your personal sensitivity to certain colors is abnormal and you want to try using the Color Weakness facility.
