Scott:
You can try Audio valve or Antique SOund Lab.
I agree with Dave that bi-amping is a waste of time.
B-amping (many many combinations) never worked for me because of lack of coherence. My current configuration is Apogee full range (modified) driven with one amp, the TRL GT-800. The negative effect of this excellent sound is total satisfaction which has made me lose all interest in trying out more amps and even posting on forums.
