For Speakerdude:you right-if you will go from 10AWG to 8 or even 6-will be significant improvement-I already experimented with my dedicated line (I am electrician):just what you need do right-install 20 amp circuit breaker,because your receptacle 20amp(or 15amp,it's same).
Re-wired to 30 amps?
I've seen posts here where guys have re-wired and increased their home elecrical circuits to 30 amps to accomodate their power-hog electronics. What is the typical ampere rating in a residential elecrical circuit?
