Salectric has his own experience to go on which is opposite my experience, Yazaki-san, Jeff Day, Jim Simth of "Bettter Sound" now Jack Roberts (the Beatnik) amongst others. As we always say, YMMV. I've used Wire World Eclipse and in my system it does not do for my system what it does do in Salectric's system. I think Jack Roberts put it succinctly, $16,000 High Fidelity speaker wire or low hundreds for DCA Duelund, which Jack thinks is better sounding. Only one way to find out, try and compare. You make the decision.
I've made my decision. I appreciate what Duelund has done; Big Bang for the buck speaker cable that will compete with anything out there and might just be better in your rig. Certain worth the try-out at its low cost. Best, Rob
