So I'm about to upgrade from my Paradigm Monitor 9s to the Studio line, and I'm trying to decide between 80s and 100s. The system is in a 12x20x8 room (wxlxh), and the Monitor 9s play plenty loud, but I want the extra detail that the Studios can reveal. What factors should I consider? Are the 100s too big for my living room? Which ones do you think sound better, the 80s or the 100s? I recently bought a Marantz MM9000 150x5 amp, so I think I have enough power to drive either speaker. Thanks for any advice.
