Theres a lot of people out there wo talk nonsense about cabling. I was on a domestic job last week pulling in around 200m of HDMI cabling, about the same in analogue audio and video and a few hundred metres in speaker cbling too. As i expected i got talking to other trades about the cables (for some reason they seem to find it interesting and come start asking questions!)
I couldnt help but laugh when this chap told me how he had spent £50 on a 2m scart lead and gradually was upgrading all his cables to this sort of stuff, why dont i get gullable customers like this!
I agree with a coment here that the resulting signals will only be as good as the weakest link, however, i doubt this will ever be the cabling, unless long runs are involved, or the cables are routed poorly or terminated poorly.
Even expensive AV equipment only has very small cheap internal cabling as they are made to a budget (unless you are buying pure exotica) so there's you weak link, a load of tiny signal cables contained in a faraday cage with all that nasty mains stuff like transformers, rectifiers etc.
I deal with a manufacturer who make a pair of domestic loudspeakers that cost £26,000 for the pair! and the cable for these are £1200 per metre!! FOR SPEAKER CABLE!!!

(ive never sold any by the way and im not sure i would want to.)
I once got a customer to take back a HDMI cable he bought from a high street shop it was a 5m cable and he paid £160 for it, i replaced it with a 10m HDMI and charged him £25 (and still made profit) how are these shops selling this kind of tat! do they claim the 1's and 0's get transmitted in
bold or something which cheap cables cant do! I gues if there are people willing to buy it, there will also be people willing to sell it!
