Their motto is "More Music from the Groove to You" - more vocal range, more instrumentation, more revealing...the main benefits of using our cables. All of their cables are based on our own proprietary Litz wire formula, using 100% copper wire and as much air as we can possibly fit in our compact designs. All WyWires cables are made by hand in our design studio in Los Angeles, using primarily USA/EU materials. Order from this shop with options listed here, or contact us directly for custom sizes and options. WyWires designs and builds products for the music lover, first and foremost. Their clients value musicality, accuracy, realism and the ability to emotionally connect with the performance being reproduced in the home.
