There have been a couple of players that were excellent in both sacd and redbook cd in the past: the classe and accuphase. I heard the musical fidelity tube sacd/cd player at he2003 and was very impressed. if you have $6000+ for a unit, there is nothing that comes close unless you listened to the 2 mentioned above for over twice the price. a new kid in town that does both sacd and sacd very good for little money if the philips dvd963sa. I have the sony 9000es and have listened to the scd-1, 777es, the marantz sa-1 and model 14 sacd/cd players, and the new philips sounds much better in redbook cd playback than any of these mentioned players and does a very good job at sacd also, all for $500.
