The following is a Copy/Paste Edit from another Thread I have contributed to.
__________________________________________________________________
"Acrolink Stressfree 6N,7N,8N, are using an Ultrapure Wire produced by Mitsubishi referred to as D.U,C,C.
This wire is the competitor to wire supplied by a rival Company Furukawa.
Furukawa stopped production of the Licensed Wire OCC and replaced it with their own unique forged wire production which is a Wire PC Triple C.
I have been using Cables with wires D.U.C.C, PC Triple C and have but am yet to use PC Triple C/EX.
I have these wires as Power Cables, Interconnects, Speaker Cables, Cartridge Tag Wires. These will eventually become internal signal wire used on owned devices. Working out which wire might be the best will need a little thought and might need a EE in attendance to help with the final selection process.
There is an individual I have introduced to PC Triple C and the impact it has had had been quite substantial. They have bought in their own Brands and have also now used it as I have, but with the additional use, being their Phonostage has it as internal wiring and their Tonearm now has it as Internal Wand Wiring.
There passing on this information to another has gone viral on another forum and many are converts to the use of it, again it is seen to be used at all interfaces.
There is only one Commercial offered Tonearm using PC Triple C as the Wands Internal Wiring.
What is missed is that the Two Wire Types, D.U.C.C and Triple C when used in combination, work extremely well.
The perception of PC Triple C, when introduced is that an additional clarity is present, it is offering a reveal further into the recording. In use it is able to make the OCC wire be perceived as it has a smearing effect when A/B compared. The difference detected is similar to the level that OCC could show the unattractive elements of an OFC Cable as a comparison to OCC.
D.U.C.C, in comparison to PC Triple C, has a similar perception of Clarity, but does have a Hue of Richness, which for me is an attraction. The hue of richness referred to has been picked up on a few systems I have loaned the Cables to. It is detectable during A/B comparison.
I know in one system the PC Triple C DIN>RCA Phono Cable was preferred over the OCC one in use. In another System the D.U.C.C was preferred in use between Phonostage and Pre-Amp' with a Silver Wire Cable used on the Tonearm DIN>RCA and between SUT > Phon'.
I can’t explain how a combination of Cables in use will benefit another system, but in my set up, the D.U.C.C is used between CDT>DAC and SUT > Phonostage.
The Cart' Tag Wires are PC Triple C, the SUT windings are Copper.
The DAC and Phonostage both have PC Triple C Power Cables.
There is no reason why Acrolink with the D.U.C.C Wire in use will not thoroughly impress, but the real edge for a system might be found if the two above wires are used in combination.
If an individual really wants to experience an uplift in performance and one that is not imagined possible on a Single Ended Cable, use Low Eddy RCA connectors on both Cable and Chassis. I have heard PC Triple C used with this methodology; it is the method I am to adopt. This is a notable experience, indelible for all the right reasons and if the effect on my system, is as heard on the system it was demonstrated on, it will be a game changer. "

I hope this is off help with your inquiry.
I will be coming away from Single Ended Cables and commence using a Balanced System. At present the only Connectors for Both Chassis and Cables are found with an OCC Male / Female connection.
Maybe one day a PC Triple C Male / Female connection will become an option.
