I have one that I use as a power strip since it's there ... inherited from a friend ... but I've never used it for audio improvement if that's your angle.
I elminated ground loops and most noise by plugging into a $150 battery backup / surge protector from amazon.
If you like I can try to create a problem with my system and see if the isobar solves it.
(in case anyone is wondering if I'm ready for the vaccine, my willingness to create problems in my audio gear for lols should clarify things for you)
And props to
@Jason for dropping not one but 3 hints about things to come. I think the gonads on my Suolo mono's shriviled up a little at ten tube headphone amplifier though ...
