I would second the Audible Illusions suggestion. I've been using one for 4 years with Bel Canto amps, and am still very pleased. They are available both new and used right here on Audiogon. Mine has been very reliable--but you will need to replace tubes about every 1.5 years.
Good preamp for Bel Canto EVo 200.2?
I got this amp last week through Audiogon contact. Now I need a decent preamp. A lot of what I have read says that preamp is maybe more important than the amp. Soundstage had good luck with a tube (Gill) pre. Cary is made across town. Would their new balanced pre be a good way to start? How about BC PRe1? Any other suggestions?
