This information is in conflict with the information I was told more than a month ago which supposedly originated from Jeff Talmadge at Denon:
"Full resolution SACD DSD will be output via HDMI on both players."
There is of course the concern whether that means the full DSD will require a DSD capable receiver and whether a conversion to PCM will result in such extreme downsampling. High-quality SACD via HDMI PCM should just be a given.
As others have mentioned, we'll need to wait for someone with a good music collection and sensitive ears who actually purchases one of these units to get the verdict. I have pretty high expectations of Denon, and I have often wondered if the delay in shipping these units has been the result of the development team scrambling to patch a few overlooked issues that they noticed only because someone inquired.
Gosh, vinyl never got this complicated.
Will it play 12"?
Will it play 7"?
Will it play 10"?
If you manually place the needle on the record, yes.
Will it play stereo?
Will it play mono?
Will it play quadraphonic?
If the quad format was compatible with stereo record players and a proper decoder is used, yes. Otherwise, no, or in some cases limited sound reproduction will be achieved.
Will it play 33 RPM?
Will it play 45 RPM?
Will it play 78 RPM?
Will it play 16 RPM?
