The Xev headphone extension cable features hand braided 24 gauge silver plated copper in teflon wire, and is terminated with a Neutrik 1/4" plug, Neutrik locking 1/4" jack, Furutech 1/4" or a variety of other connectors.
This worked just fine for listening sessions but when I was working I had a bad habit of forgetting that I was on a short leash, turning around to grab something off the the printer and - well the results where fairly predicable.
+ 1 for Trebuchet that having the XLR yanked from Amp by the wire had absolutely no effect. Just me nervously checking for damage.
Anyhow Bryan offered a good deal on a matching Trebuchet extension cable or he had a partially finished Xev cable from a cancelled order and made an even better offer as all he had to do was add another XLR connector.
So what I got was a fully braided Xev cable sleeved with black techflex that's about 9 feet (silver clad copper). [Again not sold on Silver but the price was right!]
Craftsmanship is impeccable. Uniform tight sleeve over litz braided wire and according to Bryan it's flame resistant. Hopefully he discovered this in the shop not based on customer misadventure :-o
Looks: If you read my prior review you'll see I'm not in to vanity purchases but I have to say this cable is sharp and sexy and I love the new subtle but distinctive Blue Leather Zynsonix logoed tag (Ok maybe I'm just a wee bit vain)
Durability: Office chair wheels + hardwood floors = Nothing. Not so much as a blemish on the sleeving.
Sound: Only intended to use while working but cannot discern any difference with combined 14ft of cable and base 5 ft cable so now it just stays on permanently.
Usability: Easily the best accessory I've ever bought for getting more use out of my gear.
As always Bryan is a pleasure to deal with and genuinely takes an interest in what you're "playing with" at the moment and rarity of rarities - he actually follows up to see if cable is meeting your expectations.
