12AWG speaker wire

I understand OFC, OCC, UP-OCC, after that I could care less. I have a buddy that paid 10K for OFC/teflon/tungsten. They still sound great. He tried to sell them for 2K not even an offer. I'm very sure after new terminal ends, and adding a construct or two, they would be right up there with other great cables. The great thing about some older cables they are broke in and just need a little TLC. Terminal ends that are pressure welded with contact enhancers were rare 20 years ago. You can DIY for the cost of a few tools now.. Graphene dust, 2 ounces will last a lifetime for cable building. 50.00 dollars..

It's not what you use as much as how you use it..

williewonka used OFC at one point.. They were still great cables.. Some were wound the wrong direction, they still sounded good.. :-)

@tomcy6,

Triple C is a different and an advanced forging process and stands for "Continuous Crystal Construction"

Copper is compressed to 70% by forging tens of thousands of times by gradual application of pressure with a fixed angle and direction. (The constant angle continuation transfer forging method). By using this forging process, the transverse crystal grain boundary changes and becomes more longitudinal, crystals now have consecutive connections which makes current flow extremely smooth.

In addition, by forging, the conductor density is dramatically improved by destroying the internal air grains. This, in turn, improves the conductivity and the acoustic signature of the copper.

Now sonicaly with CCC you get a smoother, cleaner and more refined sound, better extension at extremes, tighter bass, but sacrifice a tiny little of mid sweetness and weight compared to PCOCC.

This is my sounding understanding and experience of both technologies.

OCC-DUCC = Dia Ultra Crystallized Copper, is coming from Mitsubishi industries, is a different forging method to OCC but still an optimal aligned long-grain molecular stracture is created.

I have no sounding experience of OCC-DUCC, but may do for in my plans is a new speaker cable and that would be either Furutech DSS-4.1 (OCC-DUCC) or Acoustic Revive SPC Reference (Triple C).

Thank you for the explanation @petg60.! Very helpful.

That's a lot of technology for connecting our components.  

@petg60,

did you try Acoustic Revive SPC Reference (Triple C) cable
