Over the last few days, I've been reading everyone's comments and not only have I learned so much from this group, especially from Tom (thank you), I was also pleasantly surprised that there is still a loyal following to what I guess I should call the "classic phase-coherent Thiel sound" (as opposed to the current, modern Thiel Audio sound).
Awesome discussion regarding the upgrading path. Didn't think this was an option until now! Looks like the 2.7s are last on the list, which is fine because I don't usually like to mess with anything unless I think there is a problem...or unless there is something better, whether it's measurable or even if it's just perceived to be better. But alas, that's the audiophile's curse, is it not? To tinker, mess around and upgrade in an endless search for better sound.
That said, I'm guilty as charged, with having this curse! Heaven knows, if I had put the money I spent on audio equipment over the last 2 decades into Apple, I would be able to retire now, hahaha! Still, this endeavor makes life interesting. Again, thank you everyone for contributing to this discussion re: Thiels. Keep it coming!
P.S. Prof, have you decided to sell your 3.7s or trade them in for another pair of speakers? Last I can recall you were still deciding. Let me know if you end up going with the former route--I may be interested in those 3.7s.
