My friend just bought the Pioneer Elite DV-45A and we hooked it to my system. It plays DVD-A and SACD, and it sounds great. It also sounds pretty good with CD.
He was either going to get that or the Denon 1600 (both were $500 at Tweeter), but the extra SACD playback on the Pioneer won it over. It also has a button that removes power to the video section when just playing audio, and the progressive scan video quality is very good.
Good Luck,
Vinnie
