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!

Hi,

I agree to avoid ground loop eliminators.

Make sure any cable TV or antenna connections are grounded at your power strip/source.

One thing you might try is having all your components connected to the same grounded power  strip/source, and make sure each power cord is of the same length and wire gauge. Best if they are all the same manufacturer and model power cord.

Make sure you don't exceed 15 amps, or the power strip and outlet's limitations.

I agree to avoid any 

Happy Listening!

There are plugs you can buy that eliminate ground loop, Morley Him exterminator is one, you could try it out.  You could also get a cheap converter plug, goes from a 3 prong to a 2 prong plug, try it to see if that breaks the ground loops, if it does, you know the more expensive Morley plug would work, that would just be for testing as your pre or amp isn’t grounded properly when you use that type of plug adapter.  That all said, decent chance it’s not being caused by your amp or pre, something else like a wall wart, PC, WiFi / Mesh network extender, cable box, exc… good luck?
