There is much debate over HDMi cable; and I read every review going. You will find technical people say that it doesn't matter what cable you use, as its digital. Thats somewhat true to a point and therefore I'd not spend over £50 for a 1m cable. However, having worked with networks and hi-fi, I've learnt quality does matter. Two major things to consider; connectors and cable protection. The Tech cable has well made tight connectors, so you're less likely to get a loose fit. Secondly the cable has a multi layer sheeth; many of the good brands do this, but I like this one, as the braided should cancel out any interference from other electric sources.
My other brand cable was poor; it kept getting interference from something, so I ditched it and tried this - it works just fine. If you're considering buying a cheap brand, just realise you're tossing a coin as to how lucky you will be with build quality and how well those connectors are made. The cable is also stiff; which detters you from making tight bends in it. In summary; ensure it clunks well into your TV/Amp/PS3/etc - if it doesn't, then send it back for another. Then make sure you don't cable-tie it into a tight bundle with everything else.
