I owned Thiel 3.6's for 8 years. I added a REL Stadium II about 4 years after I got the Thiel's and it vastly improved them - and not just in the bottom end. When it was time to upgrade, I also wasn't thrilled with the 3.7's. I went a completely different direction and went with Magnepan 3.6's after listening to a lot of different speakers (Andra I's being one of them). They're a very different sound from everything else, but are simply amazing - provided you can feed them properly and live with their limitations (looks, placement, etc.).
Now I'm eagerly waiting to hear the new Magnepan 3.7's :)
