Your favorite OCC speaker cable

@hilde45 see last photo of the USAM link you provided. These are bi-wire speaker cables. One end has two connectors, the other end has four,  

@fuzztone Analysis Plus wants 1000% more $$$ for AG balanced ICs than Dyson Audio asks. Hard to believe that they sound 10 X better. Looks like they are recouping funds for the patent.

Patent was paid long ago, and now it’s called profit. Home Audio cables is just one channel of the business along with products and services for NASA. Analysis Plus sells a lot to the pro audio industry. Famous musicians and particularly some well known guitar players prefer their cables.

Made in America, successful, profitable, creating jobs. Great designs and high quality materials, with quality of service  Survives and thrives. How it should be.

@cmariner1 Wow, what a crew of deluded nit pickers. I'll bet a leg that not one of you could tell the difference in a coat hanger or one of these rip off cables.

Some people can hear a notable difference. Some cannot, with no need beyond zip cord or a coat hanger for speaker cables. Good for them!   

The "PC" just stands for pure copper pre-pended to OCC, and possibly different source providers of the copper itself. A 6moons article for reference, and who knows where the real story originated or what is true. The conductor is part of the design, not all of it. Designs, dielectrics, connector ends vary from one mfg to the next. Demo & listen if you can!    

Clip;

"For many years the copper wire used in Oyaide cables was supplied by Furukawa famed for their PCOCC copper. That stands for pure copper Ohno continuous cast. It’s a method developed in 1986 by Dr. Atsumi Ohno at the Chiba Institute."...

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.
