Build quality and value of Geoffs cables are superb. I've run quite a few of his cables over the years and think highly of the Duelund 50, Litz R1 Dragon interconnects as well as Litz 202 speaker cables. The Spiral 8 cables are great in certain systems also. I continue to run mostly Aurealus pure silver cables in the digital chain. I'm a big fan of the Duelund pure silver for use in digital cables.
