Designer in wall wiring - worth it?


I have two dedicated outlets for my system using standard 12 gauge with short runs of about 15' to the breaker box. I used 12 gauge in this case due to the very short runs. I have recently experienced some very positive results with Audience speaker and ethernet cables, and it got me thinking it would not be crazy money to try the Audience in-wall shielded 10 gauge cable. Has anyone tried the Audience cable or other "designer" AC cabling? Did you find it to be a significant upgrade?

If you're already running 12AWG OFC, there is nothing on planet Earth you can replace it with that will sound better. Because science.

@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.
