Thanks James I will check them out. I need about an 8ft pair and will be replacing my Audioquests
I would check out the Anticable 3.1's if you can. I started with 2.1's, which blew me away compare to some much more costly cables. I then upgraded to the 3.1 and my jaw dropped again. Just much more bass, bass detail and more meat on the midrange. I then read about the "Schroeder" method for cables and had Paul from Anticables build me a pair of custom "4.1" cables which are essentially a double run of 3.1's. I've been using them for a month and I doubt I'll ever replace my speaker cables again. Even my wife, who has good hearing but is by no means an audiophile, immediately said the Anticables sounded better than my old cables, and that was the 2.1's. I don't think she knows I upgraded to 4.1, but the other day she was sitting next to me listening to some music and at one point she looked over with a big smile and said "this sounds amazing!"
I will say I haven't used Dueland speaker cables but I am using them for interconnects and I did play around with some Western Electric 10ga tinned copper stranded cloth cable which some say sounds similar. I liked it but it was totally different sounding than the Anticable. The WE was very smooth sounding but a bit dull to me. One good thing is I could turn up the volume without strain, but I almost felt like I had to turn up the volume to get the sound to come alive. With the Anticables the soundstage is HUGE and the dynamics are life-like even at moderate volumes, and vocals are crystal clear, goose-bump inducing, without any harshness.
