Guys - this isn't meant to be another long drawn out argument for/against power cables. I've stated my case for a particular product and you can either try out an Ultimate for yourself or go about your business, it doesn't bother me much. I'm not here to try to sell you anything, however this is an enthusiasts' site and I'll wax lyrical if I so choose

Richard - a standard cable can supply 13A. It doesn't necessarily do it with low impedance, however, especially if you start looking at transient edges where Fourier analysis will tell you that there's quite a lot of high frequencies in there. Enough - I don't profess to understand the mechanism by which one power cable sounds better than another, I can simply tell you that this is the best I've heard, and I've heard a lot of cables including some much more expensive ones (which I used to own).
