OK, so the unit is here. Delivered one to a client already also.
SO FAR, I am in love. It is better than the Bel Canto cd2/dac3 combination for sure, in every way. A little different than the PS Audio Perfect Wave system.
To me the SA-50 sounds very natural - musical with a natural humanistic reproduction of vocals. SACD playback is great, and redbook conversion to dsd is very enjoyable also.
This player is going to take place along side the PS Audio Perfect Wave system in my reference room, and I doubt it will be displaced anytime soon.
I can tell you that when I reach for a disc, it will go into the SA-50. )
PM me for more.
