I have been having extensive telephone and email conversations with Tom about my love for certain models of Thiel (mostly the 3.5 and 3.7) and the one problem all have in common: a forward and agressive tendency in the upper midrange. As Tom experiments with solutions to apply to the cs2.x models, I have been duplicating his methods on my cs3.x models. He is tireless in his creativity, coming up with theories, testing them, aquiring variations of materials to compare, etc. And my Theil 3s have been exibiting the same benefits as he describes for the 2s
