For sale is one pair of amazing Stealth Audio PGS Gold interconnect cables (RCA) 1.5m in length.
This cable improved sound of every system I tried it in by allowing you to hear more music and less cable. My all time favorite cable, but my system now accepts only balanced (XLR) interconnects.
Cosmetically unit is in a pristine condition. Rated 7/10 due to age.
PGS retailed for $2000 per a 1 meter pair. RCA and balanced XLR were priced the same.
Shipping is free to the continental USA. No PayPal fees.
PGS "Pure Gold Signal": a single, very thin (0.004" in diameter), 99.99% pure gold signal conductor, surrounded by porous Teflon® insulation, and a complex cross-wrapped "return" (multiple thin strands).
PGS was beta-tested in 1999 and was in production since December 1999 until April 2002 (when it was replaced with the PGS-XL).
After several years in production and several hundred opinions collected, it became clear that the PGS is one of the most "refined" and "analog sounding" interconnect cables in existence. Note - the same as with copper and silver cables, not all gold cables sound the same! There is much more than just using pure gold wire in these cables...
But why using gold while silver is more conductive?!!!
Well, there are several reasons:
- In line-level interconnects, conductivity per se is NOT the main factor that determines the sound quality: purity, internal grain structure and gauge (thickness) of the wires effect the sound of a cable much more than conductivity all by itself. Certain qualities of the dielectric used to insulate the wires (such as its dielectric constant and mechanical damping factor) are also more important to the sound than the measured conductivity of the wire. This is not a mere personal opinion: the vast majority of foremost cable designers promote similar ideas.
- According to "The Essex Echo" article by Malcolm Omar Hawksford (which is the ONLY classical and acknowledged article on the on audio cables sound theory: 10 or 12 printed pages that explain what sounds best and why using a lot of math) interconnects sound more "focused" and "extended" if they are made of a VERY thin wire: the thinner - the better, in fact. Clarity, resolution, bass tightness - everything is better with thin wire. Why? Because thin wire allows to "move" the skin effect out of the audible range and eliminate (or greatly reduce) the time smearing of audio signal - i.e. the time domain distortion subjectively perceived as excessive upper midrange "brightness" and "boomy" unfocused bass...
- So, the wire must be VERY thin and VERY pure to sound good. But...
- Thin wire is fragile. Plus it is VERY difficult to make a very thin silver wire of high purity - since despite of using special measures, it gets terribly polluted in the production process. It is expensive - but possible to make a chunk of silver of 7N (seven nines) purity (i.e. 99.99999 pure). However, making a REALLY THIN wire is a multi (multi) step process, the metal inevitably gets polluted, and the resulting THIN wire is only 99.9% pure or even worse. It is close to impossible to make pure enough thin copper wire either. Plus - unless immediately protected by a layer of SOLID dielectric - a very thin wire "ages" very quickly and becomes even more fragile (and even brittle) with time. Oxidation is not the only factor of aging: silver oxide IS highly conductive (unlike copper oxides) - but silver is easily polluted with Sulfur and other active elements (from the outside air or from a contact with human skin). When polluted, silver loses conductivity, uniformity and "plasticity". It's not a problem with thick silver wires or contact surface, but it IS a real problem with extremely thin bare wires or silver foil used in interconnects.
- Back to the dielectric. Vacuum is best. Air is almost as good. Teflon is best of solid dielectrics (because of the fast charge/discharge characteristics = less energy storage = better transient response). Foamed Teflon is better than solid Teflon (since it contains air bubbles). The more air - the better. But - how to protect our thin silver or copper wire if it 's surrounded by a lot of air?
- So - gold IS the solution - since it IS possible to make a high purity VERY thin gold wire. How thin? Approximately a half as thin as human hair :-) How pure? 99.99% or better (24 carat gold is only 99.9% pure). Plus gold is practically grainless, a properly made gold wire is considerably more uniform than silver or copper. And it stays that way!
- STEALTH PGS (99.99% gold) cables are made with extremely thin gold conductors in a proprietary porous Teflon dielectric, and they do sound special...
