Would you think there might have been a firmware update to correct this?
I just reconfirmed that my 2808 does not apply AL24 when output from the Oppo is DSD. It just doesn't work with the Audyssey. It does apply AL24 in PCM mode and works with Audyssey. And sounds great.
One other thing. I have considered buying a 3310 or waiting for the 3311. I assume since the 3310 does not support DSD over HDMI and the 3311 might not either that I am not actually losing anything if I can't get the 2808 to work with the Audyssey as the 33XX won't do it either. They will need to have a PCM signal to process SACD. Am I correct in my assumption?
It is way beyond my ability to offer even an informed guess as to whether anything else is, or will be, affected by whatever is wrong with your unit in regards to this weird DSD/Audyssey thing. As I've said, if you have warranty, I'd send it in. If not, you could pose this to Denon tech support but they can be frustrating. There is no firmware update which affects this AFAIK, but jdsmoothie is our expert on that matter.
Of course I agree that you should use PCM from the Oppo w/ Audyssey applied in your 2808 for your SACD's, as it most certainly does sound great, as you know. The fact that if you do not have it in Direct mode, DSD is converted to PCM in the Denon, as that is the form of signal that the chip uses to apply Audyssey anyway, makes this all the more confounding.
If you do not listen loud (reference levels) all the time, you will love DynEQ/Vol, which is the big Audyssey upgrade that took place with the 2809/989 and newer models. If you can find one of those and don't need other features of the 3310/11, that would be a really good choice. And then you could tell me if you hear any difference at all when the Denon decodes DSD vs the Oppo!
It is kinda tricky as there is about a 3 dB level-match issue and one needs decent speakers.
Unfortunately in the continuing push for more video processing, height speakers etc, some nice audiophile stuff gets traded off. Denon pushed the higher quality Audyssey MultEQXT
from the 2808 and 2809 to up above those 3 series models, AFAIK. In any case the 3310/11 has DynEQ/Vol.
