Yeah, pretty ridiculous the amount of changes, right?
So far as not having auditioned the 3.6's before buying them, all I can say is that I didn't have the opportunity to do so on my 2.3's nor the 3.5's. Stumbling upon Thiel has proven to be one of the most fortunate happenin's in my audio life.
I did a fair amount of reading about Jim Thiel and his work prior to my first purchase, and that's pretty much what got me. I liked his overall sensibilities, and the various reviews I picked up here and elsewhere pretty much all contended the same opinion - great speakers at almost any price. And since we're all now relegated to buying used ones only, that sentiment resonates much deeper. (No pun intended. )
My current spate of shifting equipment has not disappointed me - though it's been a tad ridiculous. I am utterly confident that I'll enjoy them as I am utterly confident that whomever buys my 3.5's will as well.
This Thiel kool-aid we're drinking is damn yummy!
