At the kind of prices they've been charging for Hi Rez stuff I'd just buy the LP and needle drop it. :D
Also, if DSD is what it takes to get a quality master, I'm up for it. I honestly think it's the only thing that matters.
One caveat: I have Red Book files that sound spectacular, better even than some 24/192 files. IMHO nothing beats or can have as much of an influence on a SQ as good recording technique and mastering practices. The DSD albums that I have download were all developed with audiophile quality sound as the end goal. Excellent dynamic range. No "loudness wars going on". There is definitely a need to turn up the volume as compared to most modern CD releases. This could be affecting what I perceive as an improvement in SQ with DSD.
