As for Aperion vs. Axiom
I'm a big fan of Aperion from top to bottom, outrageous customer service, and flat out terrific people to deal with. I'm not a fan of Axiom due to some personal experience, but in fairness my issues were very much in the minority.
Sound-wise, the Aperion sound is far more European, much more even across the frequencies and they prefer a robust amplifier section that can deliver the high current on demand. IMHO, their best speakers are the 4T, 6B, and 6T. I'm not a fan of the 5B unless it is paired with a sub.
