I'm not quite convinced that Thiels are as power hungry as claimed. I've been using my 2.3's with a Conrad Johnson Premier 11A and it works great. The amp is only 70wpc and rarely do I see the amp pushing more than 5wpc at normal levels (the bias LED's go off). I'm certain that a more powerful amp will give more controlled bass and better dynamics, but when it comes to Thiels, the quality of the amp is more crucial than the wpc.
