the best CD player between 6'000 - 10'000 $ ?

I'll open the ball with a player about which much has been written the last couple of months

AMR CD 77
(whereby I take for granted 1) that you're looking for the "warmth" of human performance, not coloration or even tonal distortion, and 2) you do want to hear deep, clean bass if and when required)

You can surf through my threads/answers and will find other Audiogoner's systems with the AMR at the digital heart (some of which have a classical music priority)

you cant go wrong with esoteric

I had an EAR Acute that I liked a lot until I discovered the Ancient Audio Lektor Prime. Both are excellent.
