Irritating buzz


Remembered (1966-2012)
Hi all, moved to the new place, and I've got a really irritating buzz in the subs. It sounds like an earth loop of some sort.

Anyway, it's effected by graphics on the screen when playing something through the PS3 too, that makes it sound a lot worse. It's V strange.

The main speakers are not doing it at all, just the two subs, which are driven by a Parasound HC1500. This is linked to the Denon amp LFE out.

The buzz only happens when I connect the amp to the Parasoun with its cable. If I turn the Parasound on alone, no buzz.

Any suggestions on how to troubleshoot this? Or any devices that might help? I had the lot on two UPS's but took those out to see if it was the UPS's joy.
