Not sure how many owners are really on here. At just shy of $14,000 there are a lot of speakers out there. I demoed them a number of time with a number of amps (Audio Research, Classe, Musical fidelity). They are very nice but I just wanted more bass and could not justify spending the money (my 2.4s are surprisingly good/close).
I had Thiel 2.4, Sophia 3, 802diamonds all in the same room/system for comparison and spent a few days listening at a local dealer.
In the end I liked the Revel Salon 2s the best (different dealer) but never bought them, intended too.... Such is life I guess.
But back to the subject thiels are truth tellers and can get lean in a hurry so amp matching is very important. Make sure know the frontend before you judge thiel good or bad.
