Until ylou try DSD with a filter box like the Lampi DSD (no Dac chip used) you dont know what the potential of DSD is.
As to the talk of limited supply, if you have a PS3 ripper, you can go buy tons of 2nd hand SACDs for cheap on Amazon and Ebay and rip away to build up an impressive DSD library.
Quie frankly, I love well recorded DSD and PCM and want the flexibility to play both.
Nothing touches DSD128 in my experience, by the way, NOTHING.
