I listened to the Amatis in a dealer set up. I think Air-tight tube amps were used and the sound was quite good with actually very nice midrange as well. It wasn't thin at all. I guess you just have some system matching issues.
That said, I am currently using 7.2. Thiel 7.2's sound is different. Overall, it is a very balanced speaker. It has better dynamics and bass impact IMO. Yes it can sound analytical depending on components upstream as it is also a very revealing speakers.
I agree with others that you should try different electronics first and dont' buy the Thiel without audition. You either love or hate Thiel sound, but not in between.
