I recently acquired a pair of Studio Reference 100 v.2s. I'm still getting to know them, and in particular trying to figure out how to improve sound stage via room placement, cabling, and floor isolation. But so far I really like them. Very good resolution especially in the mid range and the highs. Bass can be a little overwhelming, largely because of the room they are placed in, but I've made some adjustments that have *dramatically* improved bass accuracy and sound stage, and am confident that I can improve it a great deal more still. So far they perform impressively with all music types I've played through them: ensemble jazz, symphonic classical, prog rock, hip hop, even G. Love and Special Sauce. I got them used for $1K and think it was an excellent deal.
