Contrary to what Zenieth states, there is doubt.
I suggest that you get a long (40 ft?) heavy duty extension cord and plug it into an outlet near your electric service box. Turn off every electrical device on the same fuse/breaker as that outlet. Now you have a "dedicated" line, except that it uses the extension cord wire inastead of Romex. Plug your system into the extension cord, and fire it up. Does it sound different? Now YOU can decide if the cost of a "dedicated" power line is worth it.
By the way, I do have "dedicated" power lines, but that's because my power amps are in the cellar, where running Romex is no harder than an extension cord (well almost) and my front end equipment rear side is in the cellar stairway about 6 feet from the electrical service entrance.
