Hello Dokosan, If sound quality and cost-effectiveness for high-end cables is your goal and you do not intend to get caught on an upgrade treadmill, we had an eye-opening (positive) experience w. Iconoclast speaker cables. My "boss" heard the upgrade 2 rooms away in the kitchen, and asked me what I had changed. I had explained about the upgraded spkr. cables a few weeks earlier but she forgot. When I nervously asked her if she wanted to know the price, she said "No, they were worth it." Still cannot believe her reaction, as her first question is always, "How much?"
It was easily a major hearable upgrade. Before ordering I had extensive conversations with Bob and Galen Gareis, the designer. They were very patient as I narrowed my choices. As high-end goes, they are real-world priced. And the sound quality upgrade! They started by sending me some samples to listen to. You may want to check out Iconoclast's site.
