I don't have my 500 yet, but based on what others have said, this does not sound normal. I'm suprised that is the feedback you received from Axiom, are you sure you called the right number?

If your hearing the noise during other music and/or dvd's then it should be a warranty issue, in my opinion. I would call again. Do you recall who you talked to?

You could also send Alan or Amie a PM, to see what they tell you..
