Speaker recommendation - 3K budget

Why not Nautilus 804's. I wouldn't go bigger in your 11 x 12 room.
Aerial Acoustics are nice without quite the resolution of Nautilus series.
Harbeths are another choice but hard to find. Again, not quite as detailed as Nautilus from what I've read.

An easy recommendation, Magnepan 3.6s. Though you will have to dig a little deeper in your pocket or, purchase them used. The Maggies produce a big dynamic soundstage that exudes reality in abundance. The bass is tight and defined, and the mid-treble range is delicate and delineated. Its a superb speaker but don't squeeze it because it likes its room.

If you must have a box then look at the Thiels. The 2 series should be in your price range. I have owned three sets of Thiels over the years and all were excellent. They are extremely coherent and resolving. The soundstage may not be as large and voluptuous as the Magnepans however; instrument placement and detail seem to be on par. The Thiel coherence is every bit as good.

Maggies,Maggies,Maggies...there is no substitute.....

Maggies, and although the 3.6's are definately the way to go if you can afford them, you might find the 1.6's are all you need/want.

Made a decison, yet? Sure is an amazing diversity of opinion out there, eh? I hope you can listen to some of the main suggestions, like Thiel and Maggie. They are VERY different, and your ears will tell you what you like. For a smallish room and your taste for (I gather) acoustic music, my first thought would be the DeVore Gibbon 8, a smallish 2-way floorstanding speaker that was awarded speaker of the year by 6moons.com. I've heard it, and believe it is a special speaker. It's very room-friendly and appropriate for your space. A speaker to really enjoy! Check devorefidelity.com, and give them a call!
