Great speakers that with the right equipment and in the right room can be absolutely magical. But that exactly it, they are very revealing, which is good for music, but very challenging for the equipment... basically, you will need a good source, a good pre and a good amp (or a good integrated) or you will hear the flaws from upstream. I think one of the problem you'll commonly see with the 3.6's is that you can find them for quite reasonable money, and then people add the equipment that's in a similar price range and not liking what they heard. You're going to have to spend some good money on the amp (you don't need a lot of power, not SET's but also not a 1000W+ weld torch, but you will need lots of current and something that is stable into a low load)...
Then add the size demands. Thiel's design in general does require you to be the right distance away from the speaker to have all the drivers properly aligned. That's why a pair of 2.3's may sound better than a pair of 3.6's in certain smaller rooms... And then add the fact that 3.6's need room around them to properly breath and you start getting up there in room size.
