I also can't comment on the JBLs.

But I had the Aperions in my home, side by side with my Ascend CBM-170's and Axiom M22's, the Aperions were not in the same class.

I have also heard a lot of Paradigms. Good speakers, but the Ascends and Axioms clearly offer more value in my mind.

PSB also seem to be held in good regard, but I have never heard them.

This is a good board.....the Axiom folks won't steer you wrong.
