Ruf, I got the ceramic version as the CT's were JUST announced when I got mine. I love them and have been working on other parts of my system. Eventually I may or may not upgrade the speakers, but I don't miss that much. The CT's are more detailed, smoother, just all around better from what seems like the mid bass up. It's got a bit sweeter top end for sure. If you can swing the extra 1500 for the upgrade (I think that's what it is), it's well worth it. Deep down I wish I had made that choice. If I could do it over, I'd go that route right now! I've heard a few speaker brands recently that I like a ton that I never used to like. I just think that better technology equals better sound, but to me Thiel speakers still hurt my ears and I can't listen more than a few minutes. I have a lot of friends who say the same thing. I brought a friend who isn't an audiophile to listen to the 3's (the most current model) and he was ready to leave after two songs. HE heard just what I heard. We then went to my house and listened and he said that my speakers blew the Thiel's out of the water. Granted I was using Ayre electronics, but it was through a Music Hall DAC and the Thiels were using top of the line Krell stuff. I'd love to hear them all side by side.
