Swampwalker...I think you need to get a SACD disc that claims to be "pure" DSD. No PCM involved with the master recording, or the mixdown process. On this disc, the redbook layer will have been made from the same original data, but with conversion to 16 bit 44.1 KHz PCM. Of course this may not be fair to the PCM approach, which might be better if the original master data was 24 bit 96 KHz PCM.
I don't think there is a way to do the redbook comparison for DVDA. However I don't see the need, because DVDA is basically the same PCM approach as redbook, but with higher resolution.
The usual comparison is between SACD and DVDA. Perhaps it is just because I have some superb European DVDA discs, but I give the nod to DVDA.
My Denon 2900 is away for the Underwood mod. I really don't want a tube in my system. Been there, done that.
