Your favorite OCC speaker cable

So it appears that the claims of super purification appear to be valid. At their time of release there were naysayers (even metallurgists) claiming that five and six nines copper could not actually be formulated at a non astronomical cost, and that the whole concept was all a big scam.

I am quite sold on the idea to keep on with the PC Triple C vs OCC Comparisons.
D.U.C.C is more difficult to source at a price that makes the initial investigations cost effective.
I have a D.U.C.C being returned to me this week it has been out on loan, and had a extended loan due to the COVID Restrictions on travel.
When this is returned I will reinstate a Dual Mono Volume Control Pre Amp' > Mono Block Power Amp's.
This set up will allow me to create the same trial conditions that produced the evidence that OFC was bettered by OCC in my system.
A Wire Type can be used as a Single Wire per channel and evaluated as a single channel.
The Channels can be closely balanced to see where the Centre is set.
With Different Wires in use there is rarely a equal setting on a VC Knob to produce a Centre Image.
The Wires can then be Matched Per Channel and assessed as a Single Channel only and then brought to a Stereo Setting with a Centre Image.
It don't take long to find a Cable that can offer a good impression using this method.
It will progress to be a exercise at all Interfaces with a IC Connection. 

To date the impressions being made are very good and in favour of
PC Triple C on my system.
The Tag Wires was an immediate Keeper experience.
The PC Triple C Power Chord has got me, I am keen to introduce this wire to all my devices.   
The recently introduced Din Plug PC Triple C Phono Cable in place of OCC Silver is immediate, the PC Triple C is a Keeper, the added dimension of perceived realism is very attractive.
The perception went from knowing a breath was being taken to visualising the Breath, from knowing there is a audience on a recording to perceiving the shape of the audience from the front to rear rows and into the stalls.

I like the idea that with the New PC Triple C Cables becoming available and the already owned OCC Cables a method might also be adopted where the different Wire is used at different interfaces allowing for a Tuning of the SQ to suit a preference.

The Stock of PC triple C in use and to be put into use, has now increased.
There is now a Head Shell Tag Wire, Din Plug Phono Cable with the same wire as the earth, Solid Core Speaker Cable,
20 AWG Stranded Wire, 18 AWG Stranded Wire Power Cable and a length of PC Triple C/EX Stranded Wire this one is costly.
 

@hide45, Glad you did not jump off. I am much interested in this thread. 

navships, have his wire throughout entire system, Best bang for the buck. and  very low priced, $50-$100, 
high tech aero space/navy wire

AP OFC VS. OCC (Crystal)

Comparing the Analysis Plus OFC (Copper Oval-In Micro) cable versus the next-level-up Analysis Plus OCC (Crystal), there is an audible difference for sure. I have both types and compare both periodically. Both are nice cables and do sound quite different from one another.

AP Crystal OCC:
On my system, not only is the occ crystal version more open and wider as noted by @hilde45, these cables also have:

-more low end extension of BASS
-SMOOTHER sound, no edge or grain
-larger/wider SOUNDSTAGE (yes)

Woah:
The first time I tried a pair of the AP "Crystal" OCC cables it was so different for a split second I thought an input tube on one of my mono tube amps had gone microphonic or something. Switched back to OFC, nope. They OCC cable is just so much lager, wider, spatial.  Kind of intimidating at first and they do need lots of settling in.
At first, It took a while to comprehend and appreciate the difference after having used all sorts of different OFC, pure copper, silver over copper cables from other top manufacturers. They pass-thru what is there from the source, good or bad. If you want a veiled over passive filter type interconnect or speaker cable, the AP "Crystal" OCC cables are not it.  After getting use to the occ crystal cables ended up going back and swapping CAPs on my DAC and re-rolling a bunch of different input tubes on my preamplifier and amplifiers, now hearing input tube changes more than ever with AP OCC Crystal cables. Would have not believed it myself until I finally demoed a few pairs and bought some.
