Jetter, searching for a direct comparison, I had the same experience. I previously owned the Sony 5400, and got an Oppo 83SE to audition. Verdict IMHO: for 2 channel stereo the Sony 5400 is better. Oppo Digital also has a great return policy. A well-known modder agrees ... the Sony is superior to the Oppo 83SE in stock form. I elected to get a modified Oppo 83 (non-SE) and sell the Sony. It's about the same cost (~$1,500), PLUS it's one less box - as the Oppo BDP-83 replaces both the Sony and my old Oppo 980H.
Sorry, a question about the Sony SCDXA5400ES.
Here it is: I'm looking for a new cd player, only redbook, no sacd needed. My budget is a max of $1500, new or used. So who has heard this thing? Who can say (who actually HEARD it) that it will better most, if not all other players in my price range? Is the hype so? Does it currently make boutique brands obsolete(in the lower price range)?
