Has anyone ever tried cables made with OCC (Ohno Continuous Cast) Copper?

I'm glad more people are finding out about OCC single crystal wire, but now there's even a bigger game changer that's better then round OCC single crystal wire and that is rectangular OCC single crystal wire much better performance than the round very noticeably better there's only one company that makes it, Neotech, the two reference cables that they make are the Amazon which is the silver OCC rectangular wire and the Sahara which is the copper OCC rectangular wire, I like the Sahara interconnects better than the Amazon because they use both copper and silver as opposed to just all silver in the Amazon and I can tell you they bettered my Harmonic technology pro nine SE speaker wires and my Harmonic technology magic ll interconnects, I could hear deeper into the sound stage it was blacker everything was better not cheap though but well worth it, check them out.

These Wires are Superseded now, the Company that Pioneered the production of this Wires Formation under license, have long abandoned the Method.

The Wire now on offer is no longer drawn as per the OCC design.

Now the wire is formed through being forged and is a purer/softer wire.

Have a look at Furukawa's PC Triple C or PC Triple C/EX. This wire is now found in many Brands Cables. 

Alternatively, Mitsubishi produce an ultrapure/ultrasoft wire known in Audio Usage as D.U.C.C or Stressfree depending on whose Cables the wire is found in. 

I can assure you, in the same way I dropped OFC for the use of OCC. I no longer use an OCC Wire Cable as a result of these wire types. The New Forms of Wire are extremely attractive in use.

Thanks for your post but it appears PC-OCC is still being used by many long after Furukawa decided to cease the production. Interestingly, the PC-Triple C came from FCM (Fine Chemicals & Materials), part of the Furukawa Group and its wholly owned subsidiary.

“FCM proposed copper for audio and video applications, which is obtained in a process similar to forging. As emphasized in the Acoustic Revive company literature, one of the first companies to offer complete cables using this kind of copper, the new process is clear reference to the Japanese tradition of forging swords. Copper wire is repeatedly compressed (struck), which reduces its volume by 70%. The strokes are made at a certain angle and direction, determined through experiments. This process is not so much concerned with removing copper impurities, as these would have been eliminated at an earlier stage, as with achieving the most compact arrangement of individual crystals, bridging the transitions between them, and therefore reducing a diode effect, i.e. uncontrolled electron hopping between the adjacent crystals. The repeated compression of copper also pushes out the air and oxygen molecules present in the material. The obtained copper has been called PC-triple C, from ​​Pure Copper-Continuous Crystal Construction. In the final production stage, the conductors are subjected to an aging process, where larger crystals coalesce with each other, forming monocrystalline areas”.

I am pretty happy with my current Japanese cables which uses PC-OCC copper but do have plans to try a cable using the PC-triple C in 2023. From what I’ve read, the PC-Triple C sound more open, energetic in the midrange and in the treble than with the PC-OCC cables. The bass is not as dense but more articulated. What has been your experience with PC-Triple C? And what brand you’re currently using?
