Shutting off amp noise

When I turn off my poweramp (bel canto evo2), there is a small noise through the speaker, even though the preamp is on. Is this indicative of a problem? My other amp (rotel) doesn't do that.

I think it could be my (loose) rca connectors, one of them created a buzzing noise when loose.

Since some digital amps are succeptable to RFI interference like the Nuforce for example, you might try relocating it or plugging into a different outlet. Do you have a tuner very close to the Bel Canto?
