I substituted an inexpensive HDMI cable from my cable box to my SXRD HD TV, replacing component cables, and there was a marked improvement in clarity and detail. Not sure of the technical reasons (or if a better HDMI would be a further enhancement) but the difference was not subtle.
Over as AVSFORUM there is a growing number of members who have purchased higher-end HDMI cables and they are getting easier 'handshake' between the components. The HDCP (copy protecting software) is unreliable and there seem to be more problems with some cables than with others. The wireworld brand seems to be the best buy for the price.
