I agree with Minorl. You want a dedicated power source to make sure that 100% of used power is going to your amp and not shared with other devices.
You also want to isolate your amp voltage source from noise coming from other ground wires. I have used dedicated wire and circuit breakers on my Krell monoblocks and they just sound fabulous.
If you have the money, use the best AC power cable and receptacle you can buy for your amp, they make a difference. I'm using Shunyata Anaconda CX series power cords on all my audio devices and Furutech AC receptacles as well.
AC receptacles are often neglected by audio enthusiasts, I got much better bass (tight and resolved) using audiophile grade AC receptacles.
