If I were you I'd take the opportunity to listen to some other speakers rather than jumping on another pair of Paradigms. Nothing against Paradigm at all, but there are tons of excellent competitors in this price range. Three I'd recommend auditioning if possible would be Joseph Audio, Vandersteen, and ProAc -- any of which I'd take over Paradigm (BTW I had your Studio 100s in my system on demo so I'm familiar with the sound). Just perusing the Audiogon speaker listings, there are models from PMC, Revel, Usher, Reference 3a, and Joseph Audio at $4k or less that are worth a serious look versus the S8. Just sayin', there are lots of options. If you give more of an idea of specifically what you're looking to improve upon and what aspects of speaker performance are most important to you along with budget, you'll get lots of other good recommendations here.
Ill just add add that at this level you'll eventually want to upgrade your upstream electronics to get the most out of the speakers. Personally I'd start with the preamp FWIW. Best of luck in whatever you decide.
