I've bought a number of them in the past year or so ranging from 10-20 bucks a piece. Soon I'm going to purchase a new Yamaha receiver that has HDMI connections and I need new cables. My question is, is there really a difference in quality between a 10 dollar cable and a 50 dollar cable? Some I have even seen higher cost but I don't get it. Anyone who can get technical on this would be a huge help. Thanks
