I wonder if anyone can point me in the right direction with a little problem I'm having. I have a Sony widescreen TV, a TAG AV32R and a Primare A30.5 pre-amp. About 5 weeks ago, I was burgled and they theives were kind enough to remove the TV, DVD etc, but left all the audio only equipment. They worked fast and just removed all the cables out the back of the TV, not touching anything else on the AV processor/ hifi side. But, ever since then (i.e. not beforehand) I have had this really annoying earth buzz coming out of the front speakers of my home cinema set up (PMC speakers), particularly the centre channel. I have a REL Q150 sub as well, which is also buzzing slightly. My AV eqpt is fed from 3 different sockets (probably all on the same fuseboard circuit), via Belkin surge protector power bars. The sub, power amp+TV, pre-amp are fed from different sockets. I have removed and re-attached all power sockets, power leads, interconnects and the problem persists. The earth pin has been removed from the sub to make sure I didn't have an earth loop, and that has helped the sub somewhat. Also, I noticed that when I had the TV replaced and hooked it back up to the TAG, the buzzing was reduced a little bit more, but the problem is still easily noticeable (and VERY annoying!). The buzz is definitely emanating from the Primare power amp because I can have every other bit of kit turned off, and the buzz will still come out of the speakers from this unit. powering other stuff on or off (including the TAG has no effect on the amount of buzz being produced. Pic attached of the set-up pre-burglary if this helps. If anyone has any ideas of what I can do to further troubleshoot, or ideally, eliminate this buzzing, I'd be very grateful for your assistance. Many thanks.
