I added a Parasound HCA855a to my setup and I noticed 2 things. 1) when I turn the volume up on the reciever I can hear a slight noise out of my left surround speaker of it going thru each volume change(almost like a light click sound. I checked all the wires and they are all fine. I use banana plugs for all connections. 2) I need to verify this but when I power the amp on I get a bad hum noise from the TV. If I turn the TV off it goes away. I do need to make sure it is the amp by just turning the TV on. Any suggestions would be great....oh yeah all items are plugged into my acoustic research surge protector.
