Sadly I don't have much other experience other than with dynamic driver canalphones (Vibes, CX300, Koss Plug etc.) so I can't give a Super.fi comparison specifically (knew I should have gone to the NC meet). If it's any help the sound signature is best described as a forward mid-range, with bass that is good but isn't heavy like a bass head would like (apparently not like the Super.fi EB) and treble that is good but isn't overly peaky and bright like you expect from Grados or Etymotics. They're somewhere in between. I've always heard that Super.fis have pretty good bass, and I can imagine the two have some similarities from what I've heard, but I can't say for sure.
Basically the Klipschs are good all-arounders (did I just make up a word) everyone would probably be able to find something that they like about them, but they don't really excel anywhere as far as sound goes. They do have good detail and positioning, but they have the typical IEM sound-stage.
