I think it's preferable to treat the actual problem rather than use a Band-Aid®-type remedy. All that's needed is to get the your preamp and amp grounds at the same potential. Do you have a dedicated line? Can you get these components on the same line?
Experience with Inline Ground Loop Eliminators?

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.

@erik_squires - I followed a series of diagnostic steps from ChatGPT. When I disconnected the RCA cables between the LTA and AGD units, the hum went away through the speakers. 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… |
