Higher capacitance will start rolling off the higher frequencies

Quit just parroting stuff you read on the web. For normal runs capacitance will never roll off the highs in the audio bandwidth. It‘s marketing BS by shonkies like Blue jeans. Do the basic maths.

And the assertion you made above is incorrect. People do hear a difference: on a regular basis, as many of the previous posts indicate.

My observation was that the Home Depot wire is better than the spools of... what was it 20 gauge? 22 gauge? Two conductor wire that was the only readily available wire 30 years ago. Generally good to hook up a system that wasn’t likely to improve much with a high end wire choice. 

@cakyol
I can GUARANTEE you that NOBODY on earth will EVER be able to tell the difference between that wire and something costing 100s of dollars per foot...

Yes, read all of it and totally disagree with polar opposite experiences, is why I replied.  Tested various (obsessively) many times, all sorts of different capacitance and inductance types, spool, self made, and professional made, single and double runs, bi-wire. In a truly revealing and transparent system, good ears can hear a difference.  Have several colleagues with the same conclusions with more than 50yrs experience each.  Some of which are 40-50 year techs in the industry.   

For your ears you can guarantee anything you wish.  Not for my ears.  Maybe you can get rich if you can convince people otherwise.  Best of luck. You won't sway me, been there and done that too long. Thanks. 

roll off the highs within the audio bandwidth significantly enough to be audible

That Kharma tinned copper wire looks like it's made the same way that Supra wire is. I've tried a couple of Supra's cables and they have that nice, warmish, rounded off sound that's pleasant but not accurate, revealing and life like, to my ears.

Been there, done that, moved on.

All the best,
