ground issue? Did this just start happening, any changes in the set up?
Evening Jim
You got my mind thinking some more on this. This weird buzzing just started happening. Before I was using this preamp as a tube buffer. It was between an Oppo BDP 83 and a refurbed Accuphase C200. When I was using it as a tube buffer Volume was set as a fixed point as well as the input. It was barely touched and when I did touch the controls nothing was heard. Now I'm bringing it back to full preamp duty as the right channel on my Accuphase is acting up.
Regarding the ground loop. Good point. I may have to test that theory out more. For kicks I took an Ebtech Hum X and put it on the preamp. Still had the weird buzzing issue.
Info about the Ebtech btw

Well Thanks again for the ideas. You got me thinking about more potential issues. Best of luck with that MiniDSP24. I found a video on youtube where a guy was explaining stuff about it and told him of your issue. No word yet.
