What is interesting is that (to my knowledge at least) none of you audiophile-outlets aficionados has stepped up to the plate and wired a homerun from listening room to electrical panel out of 10AWG Furutech all-silver cable.
But wait! Even if one spent thousands on an Audiophile electrical panel, that panel is still wired to horrid aluminum service entrance cables! And what goes on in the street beyond that, forget about it!
So, going one step further, what y'all seem to need is the aforementioned silver cable in-wall wiring leading not to the grid, but to a dedicated Teslawall charged by solar panels.
One step further? Have your gear modded to accept DC straight from the wall, eliminating any unnecessary DC to AC to DC conversion.
Want really clean power that can actually make a difference, unlike a measly $500 outlet on its own lonesome? Do the work, guys.
