Dedicated Power Line - Directions for Electrician?

My understanding is that having a dedicated power line from where my electricity enters my house, to the outlet where I plug in my audio components would do a great deal to improve the sound I am getting from my system.

My guess, however, is that a regular electricion might not know optimal way to do this. How I can describe to the non-audiophile electician what kind of wiring, AMPS (110 or 220 or whatever) and set up to do.

Is there someone here who can tell me exactly what I need to do to have this work done is such a way that it will result in the best power set up for my system (Mac c-46, Mac 352, B&W 802D's)?

Any help would be greatly appreciated!
