Parasound HCA 2200 Hum problems

was interested to see this,thought mine was isolated problem my 2200 11 hums thru transformer,what can be done?

I have a Parasound 1206. I'm all for a lower noise floor. Any suggstions would be appreciated.

I have a Parasound HCA 1200 II that hums through the center and surround channels (not driven by the amp) unless I disable the ground.

My CD player sends a signal into the television sets in all of my rooms with them and creates herringbone lines on a couple of channels. It does this when set to standby or powered up for play. If turned off completely there is no problem. I do not play the set next to it wwhen listening but others are annoyed watching sets on these channels in other rooms. A power conditioner did not help even plugged into the designated didgital sockets. What will filter out this noise?

Ljgj, I'm having the same problem, I think. I hope there's somebody out there that might help...
