It seems crazy that after spending a few thousand on a component that comes with a stock power cord that spending another thousand on 5 or 6 feet of power cord can make the component that much better but it does. Unfortunately my experience is that the more you spend on power cords the more you get back. I have been using Wywires Platinum cords and am amazed at how much better the music sounds. I have their digital cords for my DAC and Music Server and they make a difference over their regular power cords for those components. They have 40 % off sales several times a year at CableCo or direct online.
If you are going to start with one component start with a source or at least the pre-amp. The amplifier can't sound any better than the signal it is getting.
