Well for me was a no go the attempt of star ground gave me muddy sound.

It's an attempt to add my pro. power Amp in to the mix. 1\4TRS to RCA For atmos. a little much at 450 per channel though can't bear to use my 3channelADA1250 for that role, Makes my M80s and VP160 so full at 40 & 60hz. My MRX720 doesn't like the Coax. line I used for the hook up, nor the pro amp. Tried Chassis grounds to a Monster Powers "Ground lug". Sadly in the last couple years have gone from mainly Monster cable to dumping the junk only one power bar "clean stage1" and my "clean stage2 power center" left. Figured the solid copper and shielding might help. Just made my Tidal through wireless Playfi sound muffled?

The cables all gave me all kinds of noises dumped them for Canadian Mono price "Prime Cables" voilà noises gone.

Have been watching a lot of PS Audio Tube Vids. They make a power regenerator sounds pretty good for eliminating loops. A Little to high end Toroidal power and such inside. "Supposed to give Amps. and sources direct current on demand".
