I was also considering Aperion when I decided I needed new speakers. The free shipping both ways, CNET reviews, aesthetics, snazzy website, and the fact that they're based in the US were compelling details, but in the end, it seemed like Axiom was more serious about audio science and had the background to prove it. I never got around to hearing the Aperions, even though I have a friend who lives in Portland. I would still like to sometime. Anyway, I like supporting Axiom's philosophy, and I've been very happy with the performance.
