I owned 10Ts for many years. You do need a clean and very powerful amp else the bass will overwhelm you. I don't think they have the dynamics of the newer Thiels and many modern speakers. You may consider waiting for the new CS 3.7 or possibly Avalon Acoustics. Goodluck.
Thiel CS3.6 and Aerial 10T Comparison
I currently have the Thiels and have been really happy with them however, a while back I had heard the Aerials and was very impressed by them. I'm thinkng about replacing the Thiels with the Aerials. Does anybody have experience with both of these speakers and could advise if this is a good switch or not?
