Ohg your amp is awesome by the way, I thought you were talking about switching to a KSL, I have heard the KBL's being run mono are quite good, I almost purchased a KRC-HR and was advised not to as it is supposedly "the most finicky and ready to break unit they ever made" To quote a friend (For what its worth, might be true might not.
Id try another KBL when you find a good deal and sell it if it doesnt fit your needs.
