I don't understand the last two posts but the short answer is yes, dedicated lines are preferred to plugging into an outlet that shares with multiple other items.
Every outlet, switch and additional run of the electrical is a break in the line. Most people have builder grade electrical outlets and many have marginal wire gauge.
Running a single (10 gauge Romex) copper line direct to your stereo system will pretty much always benefit a good quality system.
On my system it was absolutely huge, I heard the before and after and so did the twenty or more people that visit me regularly.
There are dozens of posts on this topic at Audiogon and many, many Audiogon members that report benefit with all brands of equipment.
