It's just what I've read. When I was at Fry's I looked at the one rack of DVD-A's and the two racks of SACD and bought a cheap SACD player. I don't really know anything about the subject. I was just looking to replace my CD player. The sony sounds much better than the old NAD I was using with an outboard 18 bit DAC on my CD's so I'm happy. The two SACD's I have sound much better than CD but not as good a LP.
