I bought a bunch of these for my home theater. It is a 16 channel system with various power amps so it took a while to sort out and these are left over.
Bought new from Parts Connexion, an authorized dealer, in original package with certificate. As new, lettering perfect. I installed them for a while but they are probably not even broken in.
when introduced it was second from the top behind the Golden Reference, although many preferred this cable over the Reference... a real giant killer
see my almost 20 years of perfect feedback and buy with confidence.
