No cable into the preamp. It is in a dedicated two channel system. My cable modem is in the same room plugged into the wall but no interconnect to the preamp.
Have you tried disconnecting your cable modem from the wall outlet? Just because it's not directly connected to your preamp doesn't mean that they don't share ground circuits considering that both outlets are in the same room. Cable modems are notorious for causing hum.
What's it gonna cost you to try it?
