I bought a Belkin HDMI cable for my Denon 2910 not realizing I already had one (came with new DirecTV HD stb). I'm thinking this is great as now I can save $150. For kicks, I decided to A/B them and see if I could see a difference. Lo and behold, I'd swear the Belkin cable has better contrast and color depth. Am I losing my mind??? I'm pretty conservative when it comes to cables and in fact use plain 'ol 12ga for my speaker wire, and that's analog! With a digital cable, the signal either gets there or it doesn't, right? Is my mind playing tricks on me or is there a rational explanation for this?
