Crackling noise

I finally have my basic system set up Krell Phantom, Krell 3 channel amp, and Rotel HD CD player, and SF evolution monitors.  All of a sudden I have a low crackling noise and it happens only in one channel.  It's present when I disconnect the CD inputs.  Also it switches from L channel to R channel when I switch the XLR cable; it doesn't happen to both channels.  I switched out for new fuses.  Noise does go away when I turn off the power amp and leave the pre amp on, which should normally happen, right?  Any ideas?  I contacted KRell and they are out of the office.  Just doing preliminary homework until Monday/Tuesday.

Hey Auxinput,

Did just as you suggested and the (Red) XLR output is the culprit; crackling/static is heard in whatever speaker is plugged into the port. Once again, many thanks.  Easy fix or send to Krell?

Yes I plugged both cables in the same port and both times it occurred.  It did happen when I plugged the cables in the Grey(left) XLR port. My dealer asked me to try w the rca cable to see if I’ll get a similar result.
