Signal and power conductors each double shielded with aluminum foil shields and silver-plated copper braided shields You want to hear every detail of your digital music files, movie soundtracks, and more. You don’t want even a trace of electrical noise potentially covering anything up and compromising the authenticity. Unlike its predecessor, Premier XL USB, the new MKII version doesn’t use two USB-A connectors on one of the ends, since most audiophiles don’t rely on their USB cable to power their DAC or other gear. One USB connector on each end keeps things neat and simple, while retaining all the advantages of the original XL design. The new Premier XL MKII USB uses USB connectors that are just a bit narrower than the previous XL version, making it even friendlier to use in tight situations. It also features nitrogen-injected foamed PE polyethylene insulation, quad shielding, and a tough woven nylon braided jacket. Premier XL MKII USB is packed full of other premium features, too. It boasts precision-wound 23-gauge signal conductors using Cardas Grade One Copper plus a 6% pure silver plating. Try the Premier XL MKII USB cable to hear the difference yourself.
