For American made, there are quite a few offerings that might fit what you're looking for:
Magnepan, Spatial Audio, Induction Dynamics, Vandersteen, McIntosh (?), Magico, Klipsch Heritage and JBL have been mentioned, already.
Triangle Competitors?

I’m thinking about a new pair of Triangles ($8000-10000 new). Are there any loudspeakers (maybe American made) that have the easy to drive, lively sound of a Triangle loudspeaker? This would be my 3rd pair.
