Just wanted to add my impressions very briefly: I heard both the Paradigm Studio 20 and Studio 10 recently, although at different stores. Both felt very accurate, fast, clear and punchy. The Studio 10 had less emphasis and extension at the low end, comparatively (obvious) and in an absolute sense too. I might be happy running the Studio 20 without a sub, but probably not the Studio 10. Overall, I had the impression of brightness and a forward sound with these speakers. My only complaint is that I might find them to be a bit fatiguing after a long stretch.
