I agree with Spencer. The JMs will be different than the other two. The Frenchies have life to them whereas I feel the Sophias don't - they felt like they were very plain and changing amps didn't seem to help matters. I have only heard Studios once and it was brief but excellent.
In terms or articulation and imaging, the JM Labs Utopias are fantastic. You may get a tad more resolution with the Americans but less toe-tapping rhythm. Of course I have not heard every combination of stereos possible with these speakers so keep that in mind.
By the way, the latest issue of Hifi+ has a great article about biamping with KR amps. Their final conclusion after trying all sorts of scenarios was that vertical biamping is the best. Thought you might be interested in reading the article. Good luck! Arthur
