jafant, your quest has been on my mind for some time now. While I only heard samples of Dan Dagastino's amps briefly at a show, so I really don't have an opinion on it. On the other hand, knowing a bit about the designer's history and looking at the specs; If I were looking for cost no object reference quality amplification for Thiel CS 2.4 SEs, I would put seeking out an audition of his gear towards the top of my short list.
