Jwp,
I am using custom dynaudio towers that are 94-96db efficiency. They are a good match with my VAC 70/70 and the 140's should be better still. Today I talked to Walter at NBS and he advised to go with a longer length speaker cable instead of lengthening my IC's...that actually is better...now I can keep the same IC's & PC's I have. I upgraded my NBS masters to the IV's which I think are a little better than what I had.
