name='Andy H']These salesmen are a menace. When we bought our new HD TV, this guy tried to flog us a £69 HDMI lead 'for top quality'. You know the kind of spiel - 'you've just spent £800 on a superb TV, don't spoil the pictures with a cheap lead'.
I explained to him that I am (or was) in the consumer electronics business - an engineer for 20 years - and that as the signal from the HD set-top box is completely digital, the quality of the HDMI lead makes no difference at all. You could connect it with bell-wire and not make any difference. Companies like 'Monster cables' etc make wild claims about oxygen-free copper and exotic production methods, but the truth is a cheap lead will be just as good.
