Perfect Vision Testing

I don't know how many people read the Perfect Vision magazine but they always seem to be totally unbiased in their reviews, unlike most others. I always looked at this mag. for Home Theater as JAMA is to medicine. Anyway they did a very extensive review of 16 DVD players and I wanted to share some of their findings.

"Despite the theoretical benefits of a digital video connection to the display, in all cases but two, the image quality was better via component than HDMI. The Denon DVD-1920 and Krell Showcase were the only machines that performed better via HDMI, and then almost imperceptibly."

"There was no improvement in upconverting SD video to 720p/1080i. If anything the image quality was degraded"

"It was also clear that there's no simple correlation between a player's video quality and cost. Higher priced machines are more rugged and attractive, but they don't necessarily deliver better images"

FYI - the 16 players tested ranged from the $40 Cyberhome CH-DVD 300 to the $4995 Lexicon RT-20. What I found amazing was how
the $750 Yamaha DVD-S2500BU was crushed, scoring a 3 in video and a 4 in audio and how the Oppo OPDV971H, a forum favorite, just did ok scoring a 6 in video & 5 in audio. The best "bang for the buck" was the Denon DVD-1920 scoring 8's in both audio & video.The best performers were the Denon DVD-5910 scoring 10 video & 9 audio, the Lexicon RT-20 scoring 9 video & 9 audio, and the Linn Unidisk SC scoring a 9 in video and 10 in audio.

What do you guys think?

If you want to read the article here's the link to the current issue including the article(s) on pages 17-27 of the pdf http://www.avguide.com/servlet/download/2485.pdf
also it appears the reviewer never checked the upscaling feature of the Oppo
The Oppo supposedly offers 480p/720p/1080i upconversion accessible in steps by pressing the remote’s HDMI button, but repeated attempts to do so generated only an onscreen circle with a diagonal line, the universal symbol for a disallowed function. The remote is hard to read

The AVGuide.com DVD player review was absolutely bogus. Those dorks claim that they couldn't get the OPPO player's DVI output to work so. . . . they just ended the review.

Purely by coincidence, the award for the best DVD players go to the same companies that throw AVGuide so much prized advertising revenue. Just by coincidence, of course.

Moe.

You may be right about that but I wouldn't be so sure. I read a few mags like Sound&Vision and Home Theater. They're pretty good but I always get the feeling that they may have an agenda i.e. advertising $$. But The Perfect Vision always reads as an unbiased periodical and they have no problem trashing a product if it deserves it. Besides if you read the reviews thoroughly you'd see that the findings are presented rather objectively. But I know most people don't want to hear that there is no real benefit to upconverstion via HDMI. Quite frankly I don't know if there is or not but I just thought the review was interesting.

It is like the Oppo they got was not the same as everyone else's. Even some of the things they liked, most owners do not rate that high.
Components output sucks big time. PF did not even see much difference and gave it above average. Could be their player was defective.
I think a good half dozen people sent them letters.
They really seem to have overrated the Denon 1920 also. Not to say it is not a good player. And could probably edge out the Oppo all around fairly easily.
They rated the 1920 so high, that the 5910 barely exceeds it. And that's a dynamite player, hardly anything can touch it.
I think the 'secretsofhifi' ratings are still the most consistent.
I have valued many of PF's reviews in the past. But after doing a lot of research myself before purchasing an upconverting player, I think they missed the boat on this one.
Although, they did prove to my satisfaction, what many of us knew. Many hi-end players have the name, and are built like tanks, but it ends there.

With regards to advertising:

These reviewers already know where the good and bad stuff is. They simply review by 'selection'. They go to all the shows, and mfrs presentations, etc. This way they don't embarrass any commercial accounts and still give fairly objective results on components that are not dogs.

An unbiased lab reports tech site that is ad supported, but they don't seem to care.

These folks do a "mythbusters" type segment as a matter of course. Check the "benchmark" section.

Another big plus.... it is free!

I do recommend perusal if $$ are burning a whole in your pocket and you do not wish to read through 300 pages of internet gossip. (never happens here of course) :)
