Not to cause a commotion, and I do not claim to know exactly "why" but that last 3 foot of cable does indeed make a difference to your components in systems like you're building. I have heard the differences that power cables can make in a variety of systems at my home and a friends. I have heard cable changes degrade and enhance the sound. Is there some "snake oil" out there in the hobby, "yes" but in my experience many of the tweaks make more than subtle differeneces in your system.
Running a dedicated electrical line to your amp of at least 20 amps will make more of a differnce than the power cord. While your at it, run another line to for your digital gear and one to your preamp if possible. I've found that these tweaks were more profound than any other tweak I've made.
