I have the
With Teeth special edition 'dualdisc'. It's a DVD-A on one side and a CD on the other. I possibly have
The Downward Spiral dualdisc as well... I can't remember. I don't have a surround setup so I've yet to actually try to listen to the surround mixes.
It's not a huge shame really... DSD is only really practical for digital mastering of analogue recordings. Going from a digital PCM recording to DSD pretty much obviates any advantage DSD may (or may not) have. And recording in DSD is impractical because none of the mainstream sequencers or editors have support for it, and very few A/D converters do DSD anyway.
DVD-A hasn't seen much use, but it's compatible in any DVD player so if fidelity ever makes a comeback against the tyranny of MP3 it should take over for a little while, at least until there's a need for something even better. DVD-A supports various PCM sample rates, bitrates and surround options. You can also mix and match rates and channel counts between tracks on a DVD-A, which is nice.
