Bearing in mind that there's 20m of twin and earth between my fusebox and the wall socket, and some huge smoothing capacitors in my Amp's Power supply to take out transients......... ..........how can anyone hear a difference with an £100 mains cable? By the way, the mains is pretty good - the voltage doesn't dip if I turn my amp up, and the resistance is less than 1 Ohm...so I'm dropping less than 0.04V down the 20m. The limiting factor is the PSU design not 1m of cable, surely! And if the PSU was really that dire, then the solution would be some bigger capacitors...£10 from Farnell. Comments? Blaze away!
