Fast & open sounding amp with great imaging 2k

Used pass 250.5.

I always liked the Classe CA-2200 which has plenty of power and headroom, is quiet, smooth, resolving & certainly fast. I know the CA-2200 was a great match with Infinity Renaissance 90's. This is a well reviewed amp & you can pick them up in good shape circa $2200-$2500. Btw the Classe pairs well with tube preamps due to it's neutrality and high input impedance (100kΩ).

There is a classic pair of VTL TT-25 Tiny Triodes for 875 which is a great price. You could even re-tube with NOS tubes from Andy at VintageTubeServices and be near your 2K budget. Also there is a pair of Music Metre silver interconnects (retail 400) that will do what you are looking for at 198 and you get a pair of Signature coppers for free.

The Unison looks interesting.
