I agree with Bigtree. Nothing is wrong with Thiel they are very good speakers, well designed and built. They do need good amplification to get the most out of them. I have a pair of 3.6's and utilize Conrad Johnson electronics and audioquest cables. I love the Thiel / CJ combination the Thiels are very accurate and detail. The only speaker I thought about replacing them with are 7.2's. I would highly recommend Thiel speakers. Dunlavy also makes an outstanding speaker although I have no personnel experience with them.
