I have a lot of concerts on BD; so the next question is important to me. Have any objective tests been done to prove that the level of jitter that is created by combining the video and audio streams on BD is audible, or is not audible, under excellent room conditions?
Also, is there any objective proof that turning off the video section when playing audio (from video discs as well as just audio discs - so I am asking two questions really) can have an audible impact, or not have an audible impact, under excellent room conditions?
QC, I'll throw in my $.02 since we just finished an evaluation with my Elite 09FD and my Oppo. First the Oppo is blazing fast, faster than anything we've seen including the PS3.
We are now using the players analogue out straight into the Six Shooter since the Elite in analogue trounced the Elite out HDMI into the Integra DTC-9.8. There was no comparison as I reported earlier. Here's what we saw and heard with three of us in attendance for the test, myself, the owner of Musical Fidelity here in So Cal (Top rated high end audio repair in LA) who also used to be in video production, and a fellow Audiophile who was interested in purchasing an Oppo.
First on BD Video at 1080p/24 the pictures were very close. The Elite may have been slightly more refined with a slightly better black level, but again very close. There was nothing here to justify the price difference. On SD DVD the difference was more pronounced. The Oppo had more noise, some edge enhancement and not quite as accurate colors. We all noticed these differences, but it bothered my friend with a history of video production the most.
As for analogue Audio the Elite clearly bested the Oppo in every parameter. It had more air, depth of image, better tonal and tighter bass, and a much sweeter mid-range and top end. Here is where the price of admission showed the most, it was not subtle.
Finally, because I was encouraging my audiophile friend to go BD and I think the Oppo is unchallenged in its price range we took it over to his house to see how it faired as a CD transport. We compared it to his Theta Carmen over SP/DIF. Now I expected the two to be fairly close on digital audio, particularly since we were running the digital into a Theta CB III which re-clocks the signal with its "Jitter Jail." I had pretty much convinced my friend that he could go BD with the Oppo and use it as a CD transport and sell the Carmen and probably make a few bucks on the deal. This was a great concept, except the Oppo didn't hold up its end of the bargain. The Carmen was much sweeter, with way more air and dimension. My friend said he just couldn't pull the trigger given the difference. He would not live without the Carmen in this comparison, and I had to agree. So much for Bits is Bits. The difference as digital music transports was easy for all to hear.
This brings me to an observation I've been getting more comfortable with, and that is a top BD player with great analogue outs may just best an HDMI audio out to a processor. In my experience none of the HDMI processors I've heard has been able to best the Elite with its analogue outs in SQ. I'm not sure if we just need better HDMI pre/pros or if HDMI is an inherently inferior audio transfer protocol. I'm beginning to lean toward the latter. Some of the new HDMI pre/pros may help settle this question. However, a close friend was discussing this with the former owner and head designer of Kinergitics and Chiro, and he said the jitter on HDMI is so bad that it will not under its current incarnation do a decent job of transferring audio data.
Hopefully this helps in your quest for a BD player. Assuming the Denon is as good as the Elite for Audio and you can use it for DSD & DVD-A I would say go for it, especially since it is copacetic with your other Denon gear. Good decision making. Regards, Norm
