Replacing Thiel 2.2's, Need Monitor Suggestions

I am completely satisfied with my Thiel 2.2's. They are transparent, detailed (sometimes unforgivingly so), incredible imaging, and solid as rocks. Unfortunately, my girlfriend thinks they are clunky looking and since we're getting new furniture she is wondering if there is anything smaller I could replace them with.

I should be able to get $900 out of them to put toward some smaller speakers. I'm considering monitors, or anything smaller and nicer looking (possibly a slim floor stander with a nice veneer.) I would prefer not spending more than $1000 on the speakers, and I don't mind buying used.

I am looking for the things that my Thiel's did well (detail, transparency, incredible imaging, large body of sound) as opposed to overly warm-sounding speakers.

You can use the links below my username to view my system. I'm still getting started, and my next upgrade will be getting a separate amp. Any suggestions for an amp to complement your suggested speakers would also be appreciated. My budget for the amp is no more than $400 used.

Thanks for any suggestions, and please don't answer with "lose the girlfriend." It's not helpful. All other advice is very appreciated.
