Jasonbourne - if you look at Iconoclast cables they measure each cable shipped and include documentation and show lower (I forget if it’s inductance or capacitance) than typical cables.
I tried their speaker cables and they were excellent and louder than my other cables, which were a bare wire stranded design with high purity copper. The only reason I didn’t buy them was that at the time Belden owned the line and wouldn’t sell shorter than 10’ runs.
Superior Measurements (especially in amps) don’t equate to better sound. Bascom King who designs some of the best equipment and does test measurements for magazines related a story of an amp that had much lower distortion than any amp he’s ever tested, yet it didn’t sound good.
While measurements sometimes help illuminate why a component sounds the way it does, but to pretend that measurement are the only thing to be evaluated, IMHO don’t belong on an audiophile forum. Even audioasylum has a no ABX policy. Also there are “ audio science” idiots who have sophisticated test instruments but supposedly don’t know how to actually measure things correctly, but who use their bogus number to schill their own cheap Chinese gear, since it measures so well.
Underwood Audio sells a house brand cable (I use their speaker cables Diamond version and gold version) that is incredibly cheap and sounds great, though I haven’t A/b’d directly with higher priced cables, but I’ve had $30,000 top Audioquests to try out on my TAD’s.
