EDN blog articlwe HDMI cables for $2 or $600? mentions article Why are HDMI cables so expensive?. In this article product researchers find little difference between a $10 and a $140 HDMI cable. The result was that the expensive cables may be made with better materials, but they don�t perform digital transmission any better than the cheap cables. At least when talking about a short cable of few feet then I don’t see any reason to pay very much for it. If your local store does not sell reasonably priced HDMI cables, then go to some other store or order on-line. Some shops seem to charge absolutely ridiculous prices for HDMI cables knowing full well that they are taking advantage of people who don�t know any better.
Another thing worth to read at HDMI cables for $2 or $600? is a story on very expensive “audiophile” cables that were sold with “story” that adding DC bias to audio cable helped sound. The dc bias to the cable was added using a 9-volt battery. It of course was adjustable ($0.05 pot) so that the lunatic fringe audiophile community could have an infinite level of adjustment and an associate infinite collective of opinions as to what was the perfect setting – pure marketing genius. Good story and “market factors” seem to sell cheap products at high price.
