Krell KRC-3 floor noise.....too high?


For my power Krell KAV 250 a I replaced not the most neutral actually preamp KAV250p  by KRC 3. Play almost wonderful but Unfortunalety on every input and  even muting On or volume to zero i hear quiet noise on my B&W speakers from distance 8-10 feet . Maybe is broken? I have silver interconnects. Noise the same xlr or chinch.

Have any one experience that problem?
