A little difficult to recommend an amp without knowing what speakers you are using but here goes:
Belles Aria Signature $3495
Ayre EX-8 $5999
And a bit over your budget:
Aesthetix Mimas $7000
I own the Mimas and have listened extensively to the others in my home system. They are some of the best integrated amps I have heard. If you are anywhere near NJ you can listen to all three as we'll as a few others at the Audio Connection in Verona.
Good Luck!
