chudleighpaul:Save your money, use the lead that came with the Sky box.
At the moment, based on my own recent experience, I support the above. I picked up a 'bargain' good quality fig of 8 lead and tried it with my Virgin V+ and can't say I've noticed any difference from the as-supplied equivalent. On the other hand, I have definitely heard improvements in my hi-fi and seen slight improvement in TV picture when upgrading power leads there. I've yet to try it with Blu-ray player.
