Sorry, I haven't done a direct comparison. But I have heard PSB's at seperate times on different systems. I have to admit that they are great speakers and were actually tied on my shopping list for top spot with Axiom, when I was looking for new speakers for my homer theater. I ended up giving the nod to Axiom for they're great value for the $$$.
