I found a thread on the Hi-Fi Choice forum - [URL=http://forum.hifichoice.co.uk/viewtopic.php?t=8453]Power cords that actually DO improve sound quality[/URL] - relating to Ultra Power Chords from [URL=http://www.sound-dealz.com/products/power_1.htm]Sound Dealz[/URL]. As they're £36 each (which is relatively inexpensive) I thought they might be interesting. Has anyone tried them?
