For Thiels I would try a Kinki Studio EX-M1 or the new monos that they are about to release. They are neutral sounding have a good grip of the drivers. Users of Kinki rate them in same region as Pass, Nagra and Goldmund.I have a set of Mirage M7Si. On the specs an average easy speaker. But no - they demand a high quality amp. My budget is not for the mentioned amps. I have tried some of them but the Kinky did is at least as good. Happy listening. Thiel is absolutely value for money. Rgs
