Home alone after my daughter went off to open gymnastics class so I cranked up the Fellowship of the Ring we were watching and I realized there's a problem: during some of the loud passages there is an electrical crackling coming mainly from the left M80 and perhaps also the VP150 that I realized is not part of the soundtrack because it is not there at lower volumes. Could this be cabling or the 663 crapping out? It is only hitting -11 db when this begins to be prominent so I would think it's not the preamp. Does any one know what I should investigate in terms of the usual suspects? Using banana plugs for the M80s and the connections seem hand wound tight and solid to the upper posts. Maybe I should start by plugging the banana plugs into the upper connections on the M80s and see if I can continue to reproduce?
