I've heard the M22ti's played through an H/K 525. It sounded just fine. One reciever or another isn't going to make all that much difference. Yes, they'll sound a bit different, but not so much that you'll want to avoid one speaker brand or another.
And yes..."Bright" is the negative way of saying "clear, detailed, and forward".
Much like "laid back" speakers are often called "veiled" or described as sounding like a damp towel has been laid over the speaker.
What sounds terrific to one person sounds like crap to another. Axiom owners enjoy detailed, clear audio. We like to not only hear the guitar strum, but the pick striking the string. You'll hear everything with a pair of Axioms. If that's to your liking, you'll love them.
