Designer in wall wiring - worth it?

@zlone here’s an idea…run 2 dedicated lines. One with hidden treasure one with romex. Terminate both with same outlets. Compare and let us know. 
 

I have 2 dedicated lines using romex copper 12awg. Each terminated with Furutech GTX-D Rhodium and Shunyata. 

I’ll add that I do not like every Audience cable and the only ones that stood the test of time are the FrontRow speaker cables and the Hidden Treasure Ethernet cable. I got rid od Audience power cords and I absolutely didn’t like the interconnects (au24sx and frontrow). Personally, I would not limit myself with a dedicated line that uses audiophile cables. I would run romex as well. Just in case. 

@audphile1 Not a bad idea, I already have two circuits, and could just rewrite one of them. 
 

@jmrrobbie1 As it happens, due to a small addition to our house a few years back, we had the panel upgraded to 200 amp service and buried to the pole. The grounding cable is a large braided copper line that runs to the other end of the basement to the copper water line. All well done and inspected. 

@jea48 I compared the P15 ground to the wall ground again today, and it was zero, as it should be. However to recreate the conditions that I measured previously, I would have to move the amp from the P15 to the second wall circuit and measure again. I will if I get the time. 

@zlone well that’s perfect! Rewire one and see what that gets you.

What outlets you have?

@audphile1 Furutechs. Specifically, Furutech GTX-D NCF(R) Ultimate Nano-Crystal Rhodium-Plated AC Duplex Receptacle.
