RE: That's a new one on me!

Yup, I've battled ground loop issues for over 15 years... I have 115db Oris Horns and 45 SET Monoblocks, so any noise at all whether from a ground loop or a noisy tube will show up. My system is Silent Now.

I tried solving the ground loop problem the 'conventional ways', and improved it, but could not achieve the silence that I have now. The resistor on the amplifier input, which you referred to, did reduce it quite a bit on on one pair of 45 amps that I had, but did nothing on another pair.

The more I studied this problem, the more I found out that very few people really understand it. It only takes a few milivolts on an amplifier different from another component (preamp for instance) and my 115db horns will produce the sound that my amplifiers amplify. Is a ground truly zero volts or could it be .0001 volt -- My Oris Horns know.
