I have a pair of 10T's and recently toyed with the idea of moving to Thiel. I ended up staying with my Aerials because, in the end, my 10T's are not the weakest link in my systme. The drivers are newer in the Thiel's, that may make a difference, depends on the sound you are looking for. The 10T's are a very romantic speaker that have held up well over the years.
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?
