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

I would say the Ayre CX-7 and then the next step up from there is the dCS P8i.

For a year I used an EAR Acute CDP until I bought an Ancient Audio Lektor Prime. Both are excellent and within your price range.

Audio Research CD7 is going to give you EVERYTHING you stated you were looking for. It gives and exceptional warmth to digital due to it being a tube based unit. I have not heard the new CD8 but it is supposed to be significantly better than the CD7 which is close to as good as it gets. The only thing I have heard that outperforms the REF CD7 from ARC is a DCS Scarlatti which is a mere $68,000. I would wait for teh CD8 which is 10K when i comes out or find a used CD7 for about half that. My system is comprised of a vandersteen 3A Sigs, Audioquest Volcano (DBL Bi-wire), ARC SP16L, ARC VS110, and a Rotel Rcd-1072 (can't afford the ones I am reccomending but I drool everytime I hear it at my dealer's) to give you an idea of my taste and where I am speaking from.

Vandersteenguy, I concur....the CD7 is the real thing.

If you want a digital player, well that's one thing, if you are in fact looking for a music player then I would suggest the McIntosh MCD500 is the best of the bunch.
