I've been enjoying my Virgo IIs with Blue Circle BC2 monos. Upstream components are Sonic Frontiers Line 3 and YBA CD1a. The sound is amazing, but I haven't tried the Virgos with another amp, so I can't really advise. I have heard that the Virgos generally work better with higher power. I'm hoping to try another amp soon too, just to see if I get a different sound. Good luck,
John.
