I got a pair of Infinity RS IIA (two 10 inch woofers, three EMIMs and three EMITs per channel),speakers on the way and had a chat with a high end shop owner who says they will require a high current amp (not necessarily high power?) and that my BK st-140 won't cut it for them...I suggested that maybe getting another st 140 and either using them as mono amps or bi-wiring...My question to you folks is will it be worth it to do this with these speaks or something else...My pre-amp is Audible Illusions Modulus IIc
