I don't know what your budget is, but have you considered used Premier 12 monos? And I don't know how efficient the AP Virgos are, but, I'd think you're on the right track getting a larger amp than the 11a for them. For what it's worth, I'm using a C-J MF2500A right now & really enjoying it (as well as not dealing with large tube amps). Just my 2 cents.
Upgrade to new Conrad Johnson Premier 140 ?
I read the "Soundstage" review but I would like opinions on the CJ Premier 140 from you guys. Being an 11a owner I would like to know if is a worthwhile upgrade. The Soundstage review mentions a more forward soundstage and I would especially like details on this. My speakers are AP Virgos.
