I was going to upgrade my Paradigm PDR-10 to a PS-1000, which has a much lower response. I've heard both and the PS-1000 is truly a good performer compared to the PDR-10. But I think I'm going to do a blind purchase and go for an SVS PCi 20-39. I've been reading how many of you have the SVS and love it. Good purchase? I like a clean, deep bass, that shakes my shirt (but doesn't pop my eardrums) a bit when there is an explosion or Jurassic puddle shakers. Anyone have experience with the PCi 20-39 or been able to compare to the PS-1000? Thanks.
