Randy pretty much covered it. The source material maybe poorly recorded and thus sound bright/hollow/edgy, when you get a good recording playing through them they shine no matter what avr you have hooked up to them. The best part about Axioms is that you don't have to crank them up to hear the detail they offer. It seems many people prefer a more laid back sound with the highs, and to my ears vocals, a little more withdrawn from the music, Axioms play all the frequencies equally so you hear them more.
