The MC2205 is a beast amp at 85lbs and 200 per channel, I have not blown the venturi's yet.
What I notice with the venturis, and even more the ryan's (at listening levels) is the stereo imaging, while not quad, certainly places instruments and voices in specific locations. It seems the wuality of the source (vinyl or tape) is important. Remastered stuff seems off to me.
A well set up listening room, with vintage electronics and new tech speakers is my goal
