PUREAV RCA

One cable has been opened so you can see the construction. You are
not buying it, please read the description farther down. Your pair has
RCA connects on each end, in tact, never used. Six pairs are available
if you need additional runs. These are the same cables under names such
as Furutech, Audience, and others.

If you want to remote your amps closer behind your speakers, these are worth every dollar.

Features:

•99.9997% oxygen-free, PCOCC conductors and high-purity, silver solder joints

•Precise barrel contact for low loss with 24k gold-plated RCA connects

•Precision-formulated, nitrogen-injected polyethylene dielectric material maintains stronger signals

•Optimized time aligned transmission at all frequencies for
consistent, exact sound reproduction using hybrid-conductor technology

•Hybrid-conductor technology for exact sound reproduction

•The cable is also 100% shielded with "double-quad-shielded" construction

•Aluminum Mylar under braided aluminum for complete immunity to noise.

•Directional arrow insures maximum shielding from the source to the amp.

Ohno Continuous Casting, single crystal copper for each wire you see.
Each wire is a different shape and size to deliver maximum definition.
Each wire is frequency chosen and time aligned. The larger wires are
bass, the rest are mid and treble. I have been using these cables for
years and have used others but I come back to these. Neutralink and
many others are the same cable, just not time aligned as these are. This
offer is for a pair of 16 foot RCA interconnect audio cables. Get two
sets (a double buy) and make speaker cables from them...that I also did
and it beats anything I even tried.

These are great cables for audio, home theater, fantastic for cars, yachts, RVs. Direction marked so the second ground wire ties to the
'head unit'. for a perfect silent no-hum ground connection.

These retailed for over $239.00 a pair

So what is 99.9997% oxygen-free, PCOCC ?

In 1986, Professor Atsumi Ohno of the Chiba Institute of Technology
in Japan, a respected inventor and scientist, after years of research
proposed an innovative method of producing a copper wire with unique
properties. The main idea is that the wire is cast instead of being
drawn. As a result, it is possible to produce cable with ultra-long
copper crystals, with the average length of 125 m and diameter of 0.1
mm. This process has been since called Ohno Continuous Casting (OCC)
after the name of its inventor. The rights to the invention were
subsequently bought from the professor and the university by Furukawa
Electric, Japan's largest manufacturer of cables for the power
transmission and telecom industries. It was in Furukawa where it was
observed that one of the characteristics that define audio signal
transmission is distortion and noise introduced to the audio chain by
wiring. To put it in proper perspective, let me remind you that it all
happened well before the cable revolution that later hit the high-end
audio industry.

Furukawa developed a process of manufacturing audio cables using OCC
wire with copper purity exceeding 99.9997%. The new version of the
conductor was patented under the name Purity Copper OCC, or PCOCC.
Until the year 2000, Furukawa was supplying own-branded cables. Later
on, it only supplied cable wire as an OEM.

This is OEM cable under the name of Belkin here is a review of the cables;
