As we all know cables are very system dependent, but although Ive changed many parts of my system over the years these cables have always performed well no matter the changes. They do have some wear, but its wire, so it works! The only reason Im letting them go, is Ive moved the speakers farther away, and need longer cables. These are a short run (4ft), best for folks with mono amps close to their speakers. I would characterize the sound as warm and with never ending bass, at least on my system. They are thick (1"dia.) and heavy, they look like the serious business they are. Gold spades at both ends.
