Yes bolt148. Your experience with the newer EP500 version has been consistent of individuals that have received the newer EP500 units with the re-designed amp. I hope axiom looks into this issue further. The newer amps they have designed don't seem to live up to the previous version. I would be hesitant to recommend them.

I’m armed and I’m drinking. You don’t want to listen to advice from me, amigo.
