Hi Matt,

Yes, I'm certainly closer than Dwight but actually a bit further than Wonderland. I'm almost in Richmond Hill -- the wrong side of Maple for you!

Anyway, yes, I'd be happy to have you come over and bring your DSP and amp. When would you like to do this? Evening or weekend?

I am sure if there were any hum in my LFRs I'd have heard it by now but our first step will be to have you listen to my existing system to confirm this. You may want to bring a CD, DVD, or Bluray that is familiar to you. Is your current hum/hiss constant or does it vary depending on source material?

We may want to get some direction from Axiom but I'm guessing the first thing to try would be switching your DSP with mine. If that doesn't result in any unexpected hiss or hum I would think it essentially rules out your DSP as being the cause of the problem.

Cheers!

Mike
