I agree with Tireguy with regards to the A50V. It is a wonderful match with the Avalon speakers. Another choice is Jeff Rowland amps. I would avoid the Spectral gear like the plague if you are looking for a "tube like" sound.
As an alternative to changing your amplification, try to borrow an Audio Aero Capitole CD player. That may solve your problem and leave you in bliss. Where are you located?
BTW, I am an Audio Aero dealer. My recommendation is based on the fact that the 2 tubes in the Capitole might give you what you feel you are currently lacking. It is heavenly.
