The longer the run the higher the gauge generally. I have settled on Audioquest Type-4. It seemingly does not add or subtract from the music, and it is relatively affordable. Yeah, would I like to get my hands on a run or two of Auditorium 23’s? Certainly, but the prices keep going up up up....they are also not readily available, well even the Type-4’s are getting tough to find. Audio Advisor, seemingly one of the only places that will still sell you custom terminated runs are temporarily out of stock. The good thing about cables is you generally only buy it once. I run two pairs of the Type-4 for bi-wiring.
