You mock but I'm seriously looking into a new mains cable for my Rotel ra-1520, I mean it can't hurt to try at least one out, can it? Ahhhh well, I'll look for last years - or if any of you know which figure 8 mains cable under 50quid can make a positive difference, now that would be helpful.
Mains cables do work, but it also makes some systems sound much worse. Weather it changes the sound to what your looking for is another story all together. I for one think some of the very high priced cables are just not worth it. unless you have very good balanced & revealling system may as well not bother.
I think some companies have made a lot of money from snake oil... >)
