"Zd542- Are you saying both Ayre and Cary would be a good replacement?"
It depends. Personally, I feel that they are both better than the Arcam. That dosen't mean that you will, however. In your OP you say that you like a warm, analog type of sound. I really don't know what to make of that because its a very subjective statement. Of the 3 players, you would probably say that the Arcam is the "warmest" sounding. However, you then go on to say that you want better dynamics and 3D imaging. There's no question that the Ayre and Cary players are better in this regard. The point I'm trying to make is that you will probably give up some things that the Arcam does well in order to gain in other areas. You really need to do some listening.
