I've tried to A/B cables over the years and I can't say I've really been able to hear the differences. Doesn't mean there isn't one, but if it's in-audible to me then I just save money. However, I've noticed subtle differences on quality contacts, such as solid spade vs a loose feeling banana..
but in a blind test I'd probably be fooled.
For me, when I'm most concerned about cable quality, is when I was performing permanent installs where first code requirements need to be met, then secondly the quality of the cable and jacket & shielding concerns. I've seen plenty of installs where "lamp cord" was pulled throughout a home, cracked, turned green & failed.
The most current wire for my home stereo is radio shack,"flat" 14ga, so it would fit nicely under the 901 stands. I soldered on spades to use on the speaker end so they would stay solid and not pull/fall out. On the amp end I use some monster 2pc screw-down banana plugs that hold the copper very tight internally. Easy to take off for bare wire vintage rcvr usage.
