I can't agree with Eldartford. I sold a Pioneer 47a (not 47ai) and replaced it with a Denon dv2900. The sound quality of the Denon is substantially better across the board, and especially in SACD where the Pioneer was poor. I haven't heard the 47ai, but its reputation is better than that of the 47a. You should do some searching on Audio Asylum and avsforum.com, where these players have been extensively discussed.
