Apparently: THAT cables in audio work, is evident to quite a number of people.
Numerous cable companies have been in operation for decades and doing quite well on the premise, including Used Cable/The Cable Company.
Some bank on the hope, to the degree: they offer your $$ back, if you disagree.
That’s not a new thing, either. ie: On page 310, of the April 1993 Stereophile, Synergistic Research offered to send four different interconnect and two different speaker cable designs (their entire line, at the time*), to audition in the home, for 15 days, risk-free.
*Ted obviously understands: everything doesn’t always work with everything else.
What some call, "variables".
There was even an 800 number(free is good)!
Of course: the term, "works" is totally subjective and what works for me, won't necessarily work for you.
I'm OK with that!
