I have to think RW is spot on. It's easy to get drawn into spending big $$$ on fancy power cables, but if you stop to think what happens between your wall outlet and the power generation company, then that 1 meter from wall to component becomes pretty irrelevant.
Even the cables in your walls will in all likelyhood be standard, cheap unshielded mains wiring, possibly decades old, with twist or screw connections, and running across each other, over light fittings etc.
Provided it's a decent, properly made cable, it's impact on any component (including hifi) is going to be negligable.
I know a few will always say they can "hear the difference", but the cost of 'top end' cables really is the world of diminishing returns.
