I’ve used them since the 1990s. I’ve always had a good experience.
I don’t use their Lending Library if I’m just considering or toying with the idea of maybe getting some new cables, but haven’t really committed to a change.
I do use the Lending Library when I know I definitely need a change, and have narrowed it down to a select group, of which I can afford one.
I usually audition four cables at a time after extensive research.
Once, I auditioned four cables and none were satisfactory. Then I did four more and found a cable that was exactly what was looking for.
No matter what the manufacturers or reviewers say, there’s no substitute for trying them in your system. That’s exactly what The Cable Company allows. It’s a great idea.
