You can buy ground isolators for RCA connections to break a ground loop. E.g. https://www.amazon.com/Ground-Loop-Isolator/s?k=Ground+Loop+Isolator
As you can see below is the master audio tracks for the movie Tenet. Any and all RED indicates the source master audio signal is hard clipping. No matter what you do with volume/gain in the reproduction process will eliminate this clipping and resulting distortion. It’s Baked into the master. Same goes for the movie Dunkirk. Another totally clipped audio track by Nolan.

It’s almost always the Cable Box! Because of how they use, Improperly, the HDMI ground pin assignment. Anytime someone says they have a ground loop hum problem. Tell them to completely disconnect the Cable/Satellite box from their AVR or equivalent. This is my learned knowledge of helping people solve ground loop issues over the last 15+ years.My experience so far is the Hypex modules seem to "expose" issues that are already there. They don't amplify an issue or make it worse, just merely allow it to be heard finally.
Agreed that if you have a ground loop hum pop up when switching out any equipment (for instance I never noticed mine til I upgraded to a Funk Subwoofer and traced it back to my DirecTV cable) it's worth pursuing. Especially if you're ocd like me.

Thanks man. Appreciate the input from someone.No hum here using RCA to XLR. I am using both Monoprice https://www.amazon.com/gp/product/B001VLW398/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
and TISINO https://www.amazon.com/gp/product/B08599HVDB/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
from Marantz SR5012 to 6 channel Buckeye Amp. I do not have a cable tv box.
Yup!
Mine was so bad you could actually feel a little bit of a static charge (like licking a 9v) touching the coax input on my receiver with the coax cable attached.
I chased the ground loop to hell and back. It's a unique setup in that I live in a secondary structure so I have power coming off the main fuse box where the utility line comes in and is grounded. And I also have my own satellite dish. And another ground rod at the secondary fuse panel in my structure.
A combination of grounding my coax cable to the AC unit outside AND using a coax isolator solved it.
I put mine right before the cable connects to the set top boxThanks Dylan, Where did you place the coax isolator in the coax path? Should I connect it between the coax lead at the set-top cable box or should I connect it between the coax lead and it's wall outlet connection? Thanks
They do not. But "popping" is pretty much non existent. Turning on I never got any noise or pop. Turning off there is sometimes a very faint pop but only audible if I put my ear up to the speakerHi @Buckeye Amps do these amps now have a mute delay circuit? Would hate to have a pop every time my processor goes in/out of standby
