Hey Voodoochile:
Good question. Personally, I've always favored tubed pre-amps for what they deliver in terms of spatiality and bloom. Coupled with a detailed, fast, and muscular amplifier like the eVosand you get sounds that's detailed and smooth with being etched.
But: I've heard the Bel Canto PRE (which is solid state) makes a great match with the eVos.
