Why only those two setups? I'd look at stuff by PSB, Paradigm or Energy before going with either of those two setups.
You can go with SVS but for the speakers I think you can get better sound. The stuff from Klipsch or Axiom that I've heard were not that impressive to me. I'd also consider the STF-2 from Hsu, it's slightly cheaper and sounds very good with lots of punch also.
