I have one of the newer computer speakers that have the amp built inside the M3 speakers. It had a problem that it would intermittently cut out. I thought it was a bad power supply but sent it back to Axiom. They rebuilt the whole amp inside the unit and now it just rocks.

They don't mess about at Axiom with the repairs. Likely an intermittent fault like that will cost more to spend source diagnosing rather than just rebuild the amp board.
