EBTech HumX

Anyone used this product before — EBTech HumX (click on blue text to see a photo).   It’s primarily function is to eliminate ground loops.   Of course, “audio gremlin” noise , especially in an analog rig (t/table, cart, phono preamp) are pretty prone to grounding issues, but also sometimes cartridge issues, ‘dirty’ AC power, RF interference entering via cartridge, etc., etc.

Anyone tried this and what were your findings?

Thanks,

Jim
