Thanks for all the responds. Actually, I don't have any cable jack in my listening room (the garage). No phone either. And when only the amp is on, if sitting 1 feet from speakers, you can slightly hear the hiss/buzz, especailly from the woofer.
When I turn on the preamp, and go for max volume, then the hiss and buzz become pretty loud that you can hear them from 3-4 feets away.
