Why are there so many different HDMI leads on the market? We all know that,by definition,these leads send their information digitally (Os and 1s) and we have always read that the signal is better if it stays in the digital domain. If this is so, are we just paying for the quality of the connectors,eg,alloy or gold covered alloy, or is there such a thing as BETTER QUALITY Os and 1s.I would like to here other members views on this subject.
