Used on full bandwidth speakers, APC S20, AVR and 1000W amp. Works great with a caveat; I needed to ground the AVR to the UPS otherwise it will sound worse. Without this device, grounding the AVR and amp to the UPS in any combination does not work. This might be one of several devices or things you need to do to eliminate ground loop and noise.Aside from that, it also reduced amp hiss and eliminated active HDMI cable noise. It works so well that you think some audio signal is lost. But before and after room calibration result is inconclusive, bumping up 16kHz and reducing 500Hz one dB, were the largest difference.

I was optimistic that this device would remove the RF or hum associated with my turntable set up based on all the good reviews. My set up is as follows: Technics TT to Vincent tube pre-amp out to Tube equalizer out to Tube amp and finally out to AV receiver.Once installed, I noticed a loss in audio fidelity including bass. When I disconnected a reverted to my standard set up without the Earthquake, volume was louder, bass returned. The RF noise/hum was present with or without this device and really noticeable at high volume like 50db so it really didn't do anything except lower audio fidelity. Not sure why. I attempted setting up earthquake between TT and phono pre amp and got the worst noise, They I set up between phono pre-amp and equalizer and although audio passed through, fidelity was lost and apparent. Then I set up between tube amp and AV receiver, and same result with a loss in fidelity. Note that I have installed my internet router and internet connections as far away as possible from turntable and amps buy somehow get this weird RF signal.So the saga will continue for me. I will surely appreciate any tips!

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.

Tengo dos subwoofer polkaudio a 40 metros de mi AVR tienen un zumbido y esto no lo soluciono, cambie el cable de audio por cable coaxial y fue la solución.

Soy un aufiofilo muy exigente. Hice mi propio subwoofer para mi home theater con equipo de car audio. El equipo es de muy alta calidad con un diseño propio, sin embargo el amplificador Alpine X-a90 debido a su calidad que es muy alta, es muy sensible al ruido externo de tierra y busque todas las posibles soluciones para reducir un pequeño hum que tenía el sistema. Hice de todo pero la solución perfecta fue este dispositivo de Earthquake GLI-200. EN POCAS PALABRAS ES SIMPLEMENTE SORORENDENTE. Pues he logrado eliminar al 99.99% el hum y es prácticamente imperceptible y por lo tanto recomiendo ampliamente este dispositivo. No hagan caso de las opiniones negativas. Ya que si el hum persiste en sus sistemas es debido a algún otro problema en su instalación o calidad de componentes. Este dispositivo es maravilloso. Tengo más de 20 equipos entre AV receiver, amplificadores, entradas como tornamesa, CD, bluray, Xbox, láser disc, Panamax, Furman, ventiladores, etc interconectsdos todos y es prácticamente 100% silencioso. Recuerden que la calidad de un sistema lo determina su dispositivo o elemento de menor calidad. Este equipo es calidad aufiofilo 100% recomendable. Solo comento que bajo un poco el volumen de la señal de entrada pero ajuste del 40% al 50% y el. Sonido es perfecto.
