Cables aren't the most exciting of accessories but, until such a time as we can go totally wireless, they're essential for connecting our audio-visual gear together, and you certainly know when you've got a bad quality cable.
It's easy to skimp on cable quality, so if like me you balk at spending almost high-double or even triple digits on cabling, you'll probably want to look away now... or see what true home cinema buffs might want to get their hands on.
If you've spent thousands on HDTV, Sky HD, and a HD DVD or Blu-ray player, the last thing you want is some crappy cable ruining your investment. TCI (True Colours Industries) Copperhead 1080p HDMI cables are designed to provide the best quality high-definition picture and sound possible, and with prices starting at £99 for a 1m cable, you'd better be serious about your home cinema!
They'll happily transfer full-HD 1080p content on cables up to 20 metres in length (they come in at an eye-watering £549.99), and comply with the HDMI 1.2 specification. They come in 1m, 2m, 5m, 7.5m, 10m, 15m and 20m lengths.
They claim the finest materials have been used. Multi-layer shielding reduces external noise, a tough outer braid protects the cable and magnetically shielded metal plugs enhance the overall performance to deliver some of the best pictures available via HDMI.
Lovely. But... very... expensive...

These cables are a waste of money for digital signals like HDMI. Analogue signals suffer if exposed to noise or poor quality cables which is why people pay big for speaker cable (often ironically to cheap speakers). A digital signal will make it or not and if not you'll either get no signal or severe tearing / dropped frames rather than a loss of picture quality.
Yep, waste of money for DVI or HDMI or anything digital, the dropoff is fast so you will know when you hit the length limit. I've got 15meters ok so far.
They put your email plain text in this blog so don't use a real one like I did.
