I think you're making a big deal out of nothing. They're just using standard Belden cable stock, and apparently they've done up an Amazon special. It's not a "silver version", as in something stupid Audioquest would do.
Whoa there....Making a big deal out of nothing is exactly the point of the analogy to acid washed jeans. It's not like I called them the jorts of blue jeans cable after all. Or the kumlauts. And nothing wrong with a little forum traffic on Tuesday am and maybe a couple of buy it nows for BJC, my favorite interconnect supplier.
Yes indeed, it's a belden coax with, inferring from the description, with silver plated conductor standard to the model. (I have not looked it up the specs on belden). According to the amazon listing:
"The cable stock in these stereo pairs is Belden 734D2. This was originally developed as a DS3/DS4 digital coaxial audio cable for multiplexed telephone systems, ....It offers low capacitance (16.8 pF/ft) and excellent braid-over-foil shielding, and has a 20 AWG silver-plated copper center conductor."
But my favorite part of the description is the first part, which to paraphrase/interpret:
'Here are some "acid washed" interconnects with a silver plated conductor in the middle. We think "stone washed" ones with copper are better overall, and that's why we use that for lc1. But there is no accounting for taste. So if you are into that sort of thing, here you go.
They work fine because the cable we re-purposed meets the necessary technical criteria for analogue line level interconnects. Hey, the shielding is really terrific, though thats nothing to do with silver plating on the center conductor. Just quality construction of non-exotic materials. And we assemble it just like our other cables (that is to say, AMAZINGLY). Except the it's about 1/16th inch thinner and has a grey cable jacket, which is probably the only way you could ever tell this apart from our standard lc1 in a double blind listening test. You know, once you take the blindfold off."
