I also did a direct A/B of the Spectral SDR 4000 Pro versus the Alpha DAC fed by a High End dedicated PC based music server, and I must say I could not tell the difference either. That will probably be the way I go with my system, especially given the pace and direction the digital/online/hi-rez computer music world is moving.
I also own a DMC30 SL (latest version), so I am kind of curious as to why one would prefer it over the current DMC 30SS. Presumably the DMC 30SS should out perform the DMC 30SL for Spectral to go through the trouble of developing and releasing it...
