I own the 9's, running with Rowland 201's and Aesthetix Calypso. They are really great. I wasn't a big fan of Aerial prior to the new line, but now I can't say enough good things.
Music? Everything from folk to chamber to jazz to world, but lots of straightforward rock and roll.
Room? 15 x 26 x 7'9" -- dedicated listening room, good sounding.
I've owned Maggies, Hales, Spendors, Linns, Soliloquys, and ADS speakers, and I auditioned Sonus Fabers (Cremona), Vienna Acoustics (can't recall which one -- but the one in the 9k price range), Martin Logans (prodigy? protege?), Joseph Audios (22si or something like that), Paradigms (the one that is around 6-8k) and a few more. The only one that I liked about as well were Wilson Sophias, and the Aerials were cheaper, deeper, more precise and better looking. And all of these speakers were very fine.
Buy the optional stands! I did and first thing, they spike the speaker to the floor amazingly well and second, you can tip them back just slightly and that has a wonderful effect on the sound. The stands are $700 but worth every penny.
You won't be sorry.
