As a brick & mortar guy, I'll openly tell people that most will not "see" a difference between cheap & expensive cables. That said, I'd rather have the 240/480 hz cables if I can afford them. Yes, the audioholics site does a great job debunking myths about HDMI cables, but it makes one mistake: the "hertz" rating has nothing to do with bandwith. Bandwidth just determines how much information can be contained per packet, not per second. Faster HDMI cables--10.2 gbps, 14.3 gbps, up to 17.8 gbps--move these packets along faster, hence the increased frame rate capabilities. Yes, the device only provides a 60hz signal, but if the TV can't pull those packets faster than 60hz, all you will see is a 60hz picture. If you have a 600hz plasma, your "ideal" cable is something rated 240/480hz at the moment. That said, most people will not be able to tell the difference. Resolution, color, brightness, hue, saturation - no difference (thank you digital signal). Motion will be the biggest difference...you'll have slightly less blur on fast-moving scenes, and less "perceived" lag in video games with higher rated cables. Is Monster expensive? Of course. Is it worth it? Not unless you're super picky and don't feel like shopping around. Result? If you're shopping here on Woot anyways - buy these cables, duh. If you come talk to me in a brick & mortar store, I'll tell you which cables are technically superior. The choice is yours.
