I'm looking for a good mains cable for my Naim CD5i cd player. Will a more expensive mains cable improve performance over the one that ships with the player. I'm a bit sceptical about such upgrades as there are such conflicting thoughts posted on the forums. I have found a Black Rhodium Supermains 13 13A/IEC 1.25M for <£50 would this be suitable and a good buy. I've seen the same lead going for £150 on other sights If you could please post some links to suitable products on a fairly limited budget <£50 it would be much appreciated.
