Thiel's are much harder to drive.
I own the Triangle Celius and am very pleased. i have heard the Thiel's several times and never liked them (however the rooms and set up were aweful)
The comments on the Triangles being bright is correct. I used an RTA to set up my system and can see the tip up on the graph. As such assuming one's hearing doesn't roll off (which is what I am counting on with older age) one can use a tube amp, avoid direct toe in or even put a 1 or 2 ohm resistor in series with the tweater until old age sets in. I run them on my 4 ohm taps which are a bit rolled off and don't point them directly at me. I love the speakers
