Thiel Owners

Dave it's just that i would like to have one of the bigger legacy Thiels for my future dedicated listening room, i would be using both the 3.7s and 7.2s as my reference speakers.
Problem is that 7.2s are very rare on the used market now days.
The last time i saw a pair for sale was in 2015.
My room size should be around 15x21x10 with serious room treatment.

Theiliste, May I ask if you plan to use the 3.7's and the 7.2's in different rooms, or rotate them in and out of service in the same room?

Rotate them both in the same listening room.
Therefore i would need to make the right choice of amp because the 7.2s are harder to drive.

I already decided that i would prefer the 7.2s over the 5is if i was going to buy a legacy Thiel.
