Jeff ... thanks, I understand that DSD is a delta-sigma modulation. Don't be fooled that its high sampling rate makes it superior to DVD-A because delta-sigma convertors require a MUCH higher sampling rate than PCM systems so that they can track a high slew rate in the signal with their single bit. DSD and PCM have different shortcomings, though both should be audibly superior to redbook CD.
Metralla ... you may have said "please", and "regards" but your post was still unnecessarily curt and condescending, and your followup post contained virtually no extra information, links etc. If you're going to denigrate others at least have the grace to educate us.
Iszak ... 2" 24 track onto 1" analog master is great for sound quality ... I agree. DSD direct off the analog master will be fine quality. I suspect that a DSD from a 24/96 or 24/192 PCM would also be pretty fantastic. Older ADCs are probably less good.
And you still need good mics, placement, a good room, and an engineer who doesn't feel the need to use every single piece of rack equipment to perform the mix. These things make more difference than the whole analog/PCM/DSD issue, but are often overloked by the audio crowd.
