Thanks a lot for all the advice. I'm going with a high quality powerstrip as suggested by several; I'm picking one without any conditioning or surge protection: just something that minimally interferes with the power going through it, specifically Pangea Audio Quattro Premier - 4 Outlet Power Center 20 Amp or Quad Power Box as suggested by @lak.
@tattooedtrackman: the nicer power cables also tend to have nicer hardware: plugs that fit tightly and make a good connection and plating that resists oxidation over time.
