I had been using Siltech MXT Pro series New Yorker in my 2-channel system, these are very good cables and a couple of other members hear have used them as well. I was trying an amp that was sensitive to the Siltech being only grounded on one end which led me to try my first Anticable Reference IC, it cured the ground issue and sounded great so I didn't think much about it, fast forward, I begin to use the Pass Labs and wondered how the Siltech would work back between amp and preamp, in comparison to the AC the Siltech magnified the sounds and lacked clarity, I also compared the AC to the new Clarus Aqua which I didn't like as much as the Siltech. In short, I unknowingly grew to recognize the Anticable provided a clarity I'm not sure any other cable is able to match, if so, it is one way beyond my price range. With my ears now opened I replaced all IC's and speaker connects with Anticable Reference. The Reference wasn't shown on the old website but they were working to get a new site up to show all of Paul's products. The Anticables allows the sound to be as pristine as your electronics can do. The Anticable offers a price to performance ratio better than any cable I have tried so far. Speltz's theory is one of the reasons cables sound different is due to the dielectric used around the wire. I feel I have proven his theory to be correct to myself because after becoming accustom to the clarity of the Anticable all the others I tried in it's place seemed to be hazey or a dulling effect in comparison.
