You have a very similar system as I got(same speaker and I have Premier 11a). If I have to choose, I will choose Premier 11a especially if you own the Thiel 2.2 as the 11a really is a match in heaven with the 2.2. MV55 is good but not as relax and effortless if you crank up the volume or listen to soft rock.
c-j buffs: MV-55 vs. Premier 11a
Anyone auditioned (preferably owners) conrad-johnson's two recently discontinued stereo tubed amp offerings head-to-head in the same system? I am an MV-55 owner who is very happy with the sound (fed from my c-j PV-8 pre-amp, through Thiel CS2 2 floorstanding 3-ways via all-Cardas Cross), but may be needing more power soon, and am considering the Premier 11a. I know the Premier ought to be better in theory, but apparently some folks have demurred - true or not, and if so, why? Also, anybody tried rolling tube types on the 11a? All input from those with personal experience is much appreciated! Thanks, Alex
