Review on 🔊 Earthquake Sound GLI-200 Ground Loop Isolator with Hum and Buzz Cleaning, RCA 600 Ohm In/Out by Kenneth Murphy

Lifebelt. I did a pretty expensive upgrade. Added: Panamax 5400 Amplifier, Parasound Halo Integrated AM Amplifier and Outlaw 5000 Amplifier. Everything is connected to Panamax, TV, DAC, CD Player, Blue Ray Player, Roku, Modem, Router and Switch. I connected my Denon amp to the Halo via a home theater bypass and noticed an awfully loud hum. Also very faint hum from all Halo inputs. I found that the source of the ground loop noise was my router connected to a TV, Denon, Roku and Blue Ray player via ethernet. all the buzz from that entrance. I still get very little hum from other inputs so I'll keep playing. But this machine, especially for the price, is amazing.
