Trying to trouble shoot slight buzz through Amazings. Does not get louder with volume increase. Eliminated equalizer from equation, tried different interconnects between pre/amp receiver and TFM-75, plugged into different wall outlets, still there. Have a hum bar on DVD's. Sounds like it may be a ground loop. Disappears when I use the amp in the receiver connected to Amazings and disconnect the TFM-75 and turn off.
My question is this: Can I hook the TFM-75 directly to the Amazings with the volume potts all the way down and see if I still have the buzz to determine if there is a problem with the TFM-75 while bypassing the receiver and not damage anything? I figure by isolating this way, it will tell me if there is a problem developing with the TFM-75 or a ground loop issue?
