Beyond a certain point, with respect to materials and assembly costs, a $5,000 cable is not better than say a $300 cable. What you hear are small differences-- like flavor notes between a varietal of wine. Is a $500 bottle of wine "better" than a $50 bottle. No. Just different. If the market decides they prefer one over the other then demand can drive costs. But for the winery to claim they have some kind of unique patented magical grapes and that this is why they have to charge $500 for that bottle is 99.99% booshwa. Cables are, without question, one of the greatest scams in audio. Many of their claims defy basic science, and their pricing has absolutely nothing to do with costs and everything to do with selling a myth of their own creation. So what to do?-- buy them, listen, live with them a while, and if you can afford them-- then just enjoy the music. Once you get into the hundreds of dollars you're going to be buying well-made cables-- no better and no worse than cables costing ten times as much, just small system dependent differences. The rest is just a marketing story that was made up in order to sell them to you.
