Cables CAN make a difference though it often has a lot to do with the kit you are using. I have seen evidence that it would be impossible to deny. I have a 5 year old Panasonic plasma. (I know that this thread is about sound however it still illustrates the dramatic effect cables can have) I have seen friends slightly newer tv's and playing gta 4 looked completely different. So much more background detail even though they were using a similar cable. I was thus so disappointed I gambled on a chord active silver hdmi. At the time is was £110! It was probably the best value product I have ever bought. The backgrounds were now clearly visible on gta 4. The difference was starting. If you disagree then please bear in mind that I would definitely have bought a new tv by now without this cable. This may have something to do with my particular tv model but anyone who thinks that a cable can't make a difference is deluding themselves. 2 seconds of footage, with a cheap cable and the chord cable would be enough for ANYONE to see the difference. I really mean 2 seconds, though half a second should be enough! I also swapped to chord odyssey speaker cables for my cm7's and it definitely increased the transparency though not always for the best especially on poorer quality downloads. To reiterate, cables definitely 100%. No point arguing. Can make a difference. It will depend on your equipment but to say it makes no difference which cables are used leaves me a bit embarrassed for the nay sayers as they clearly have not been fortunate enough to be blessed with good hearing. And when it comes to the tv effect on my panny, you relly would need to be partially sighted not to notice the difference!
