hi Bad, is it in only one channel or both equally? maybe a loose connection?
i would try one channel at a time and switch things back and forth to isolate the problem. normally impedence would only affect dynamics and frequency balance and not add noise or static.
you could even run one channel thru the Symphonic Line and one thru the Chord to try to find the problem.
also try to plug in your power cords into different outlets to see if it might be some sort of power related issue. once i had a background buzz that turned out to be the interaction of a particular power cord with my amps.
i hope this helps.
