AC Line Conditioners

I have a low hum in my B&K Receiver and sometimes my Vincent Audio amp. Currently at least seven components are plug into a Monster Audio Home Theatre PowerCenter HT 850. These include a Plasma TV and At&T receiver, CD player, Cassette deck, Bluray player, DVD recorder and CD recorder.

Would a good Power Line Conditioner be the solution for this?
Can you recommend one for me? Don't want to pay over 500 dollars.
I see some go for 3,000 dollars ex. PS Audio Perfectwave Power Plant 5.
Maybe I can get a used one with good features.

Good chance you are experiencing a ground loop hum caused by the cable feed to the At&t receiver. Disconnect the At&t cable from the receiver and take a listen for the hum.

Jensen makes a good ground loop isolator.....

You can also call your cable provider and they will re-ground the cable. they are required by law to do so.

Disconnected the cable feed (from wall to power strip )and low hum still present in amp and CD player(sleep mode). Funny thing when I picked up the power strip to disconnect the cable feed, I noticed a high pitch noise coming from what seemed to be the power strip. The noise comes and goes according to what position the strip is in. I elevated the strip on a plastic case whereas now high pitch noise is present. But still the low hum is in Amp and receiver.I will check on the ground loop isolater.
Will At&T re-ground if I mention my issue to them and it's not TV related?

Thanks

Wrong cable.....

Not the AC power cable.....

Disconnect the RG6 coax signal cable, (that comes in from the CATV provider), from the At&t cable box.
