I would say that something is wrong in the Krell Phantom. Maybe disconnect all XLR cables from the Phantom. Then connect Phantom left XLR output to one amp channel. Then unplug that XLR cable and plug into the Phantom right XLR output. This will help determine that something is wrong in the Phantom. I did have a similar crackling sound in one of my amps and that had to be serviced.
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.
