@tomthiel, I've used Mark Levinson ML331's and Krell KAV250 with the Thiels before and the Bel Canto REF500M mono blocks are definitely better than either of those. Especially in the bass and mid-bass. I don't think it's the amp.... I can borrow a few different amps from friends and test your theory, but I don't think that's it.
@jon_5912, the amps are mono blocks already, so I'm already there... :-)
