@cleeds - I don't have a dedicated line. With other things going on in my life, I wouldn't be able to prioritize getting that done. Would a dedicated line fix the problem?
In a year it's something I'd look to do, though.
Would those other devices not work for the short term?
Experience with Inline Ground Loop Eliminators?
Audio Enthusiasts -
I am running an LTA level 2 preamp to an AGD Audion MKiii mono blocks. I've diagnosed that I have a ground loop between the two units.
ChatGPT is recommending a passive isolation transformer that will go in-line with each RCA signal, breaking the ground loop via transformer coupling. Some of the recommended solutions are the Hall GLI-RCA Stereo Ground Loop Isolator, Recoil MGL14/GLIRCA and Sescom IL-Stereo-19 Pro Audio Hum Eliminator.
I was wondering if anyone has used any of these devices? Or have any recommended other solutions based on your experience?
Thanks in advance!

According to ChatGPT, it’s probably a ground loop issue between those components. Jensen seems to be the recommended manufacturer for this type of problem. Again, according to ChatGPT… |
@bluethinker So if I'm understanding your question and explanation correctly your preamp and monoblocks are plugged into two different outlets on two different circuit breakers? |
