Steve,
I have had exact same problem. I would classify my 500 as new - just got it in May. I have the recent thread that John mentions as well as an older thread on the same subject. The first thread, as I recall, I was thinking it was the monoprice cable I was using. I now know it was not. Long story short (you can check the thread for the unabridged version) JC called me yesterday and is sending a new amp. The older versions had a switch for "always on" or "sleep" mode. It might behoove Axiom to reconsider the earlier revision.
Out of curiosity, what model receiver do you have?......Rob
