I've have the yammy rx-v2500(unused) and am considering the exact speakers that u have. So i am watching this thread with keen interest, your ep500 experience thus far is a bit disconcerting. also I was under the false? impression that the set up mic of the yammy did a good job bummer on that front as well. hope u can get it sounding exactly as you want and expect it to sound m8.

If I may ask one question to whomever does the yammy push enough "juice" to optimally drive the ep500? not sure on the 2600 but the 2500 pushes 130watt a channel.
