I have received several e-mails at work from companies trying to sell me 'high quality' HDMI cables. Prices vary, but some are charging as much as £199 for a 1 metre length. I have used the Pioneer HDMI cable which cost nowhere near this. (I am told they can be bought for as little as £20) Has anybody had the opportunity to compare different HDMI cables, or have any opinions on the value of expensive digital cables? I'm not convinced but am prepared to listen.
