I was using XLR's and I have the Sherbourn PT-7030 so that wasn't a problem with mine. I know others including Archaea have had success but they weren't using XLR's right? Are you using XLR's now? Does it hum with just the speakers connected? I'm no EE either but through the process of elimination you should still be able to narrow down which component is the culprit. One way or another we'll figure it out.
