After trying a lot of units including the 840C, I too kept the Sony 5400. I found the 840C a little lean and lacking punch (most noticable on bombastic classical or rock recordings) but otherwise a very fine sounding unit. The 5400 does everything well. The Bryston BCD-1 was the only unit that beat the Sony IMO, it offers the best you are there imaging I've heard under $2500. The Sony of course, plays SACDs and it plays them quite well.
