Speaker Cables

... Years ago, I think it was Stereophile or The Absolute Sound, just for fun, went to Home Depot and got a 12 gauge extension cord and threw it into the mix. It was actually really good. So, for my let's see... $5 or 6K system crammed in my office it is great. But for my main system with Sonus Faber Amati Traditional speakers and All Audio Research Reference stuff, it doesn't cut it.

While I was building some speakers using White Supra for internal wiring , and using Cardas bi-wire or Apature or AudioQuest for my main speakers over the years, thought I'd give the "Home Depot" wire a test while waiting for parts.  Turned out to be a waste of money for a test. 

Tried both, the extension cord -and- the brown roll wire test. Neither were really any good, kinda grainy, not smooth.  Would be okay for a cheap 3rd system with veiled over speakers or something.

The whole "just go to Home Depot" and get some wire is a joke or its good enough for a basic system at best.  If it makes no difference on a system compared to other decent OFC or OCC cables, either the system itself is mediocre grade or there is a hearing problem going on with the listener if they are unable to discern a difference. Best of luck. 

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.

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.
