Kudo's to BB4TB. He speaks the truth. For about the same price as one of those fancy look good cables, you can run a dedicated 20 amp circuit (that too a bit overkill for a RR2150) that will far and above be more benificial than just the fancy power cord itself. Or better yet, a decent power conditioner for about the same price will offer cleaner power and a good degree of protection from line surges/irregularities. Another good point by BB4TB...If you are in an older house, the outlet may be oxidized and paint splattered from years of use and for about 5 bucks you can replace it either yourself of have a friend who knows how do it for a beer.
