Sorry for the correction havocman but occ has been with us a little shorter (1991) and yes is a considerable upgrade compared to ofc. Trple C is a more advanced manufacturing process and for me the better sounding too. You cannot go wrong with either though.
Unfortunately with cables you pay you get, overpriced maybe but what isn't.
So many times i have found out, searching for the century deal, that low budget cables called "giant killers" are nothing but very ordinary in disguise. Better save up for something better. Different systems different results, different ears, but house sound is real and easier to hear when a complete set of cabling is introduced in ones system.
Cables should remain in a system for a long period to show what they are capable of, swapping more than often is a waste of time.
I have never listened to SVS Ultra or Tuneful cables so i cannot comment on reviewers findings but i found reviews for Kondo, Acoustic Revive, Furutech to be very close to my findings.
