Fixed the problem
TLTR: It worked like a charm in my case. Professional here. Had a massive hum problem on a high end system. Since this might help some of you I'll try to quickly describe the system. It was a high end stereo system incorporated into a home theater system. When listening to music the stereo system was using an integrated stereo amp with 2 digital sources and one analog source, no problems there. When the stereo system was switched to watch movies or TV, HT bypass was engaged on the integrated stereo amp and a surround sound receiver would handle all the audio and video processing. Important note, the surround sound receiver was connected to the integrated stereo amp via RCA connectors coming from left and right Pre Out outputs. The problem was I had a massive hum coming from projector's HDMI cable (8K certified optical HDMI cable). Couldn't fix it no matter what. Decided to give this thing a try and all the hum was gone just like that. The system is silent now. Would not hesitate to buy again.

Solved Groud Loop buzzing and hum in my Home Theater set up!
Life saver. I did a fairly expensive upgrade. Added a Panamax 5400, Parasound Halo Integrated am and a Outlaw 5000 amp. Everything plugged into the Panamax, TV, Dacs, CD Player, Blue ray player, roku, modem, router and switch. I ran my Denon amp through the Halo via Home Theater Bypass and I noticed a horribly loud buzzing sound. Also a very faint hum from all in puts in the halo. I determined my source of ground loop noise was from my router which has Ethernet running to the TV, Denon, Roku and Blue Ray player. I ran this unit between the Denon and the Halo and not only did it take away the buzz, also removed all hum from that input. I still get a very faint hum from the other inputs, so I'm going to continue to play around. But this unit, especially for the price is amazing.
