Thiel Owners

Update on my Journey, kinda fits in with the above. 
Thiel 2.4s, Proceed Cdp direct to Bryston 4B SST2 

The Bryston 4B SST2 was detailed with a powerful bass but too tight but quite harsh. 
It is no longer in my system.
I got great trade-in credit and price on a PS Audio BHK 250 power amp. Thank you TMR audio for assistance in recommending this amp.
Bingo!!
Right out of the box, what a wonderful combination. Balanced and wonderful sound! The sound is tonally right on. Much more detailed, smooth , and musical then the Bryston. So realistic, I can separate out individual background singers. I can resolve what I call the “woodyness” of a cello, the timbre and subtle vibrato.
This is releasing the Thiels to shine.
Man the bass is full and bottomless, yet no booming. A good  description is the bass is precise. 
Imma let it cook for the next day or two and post what happens.
I’m really pleased .

I'd guess the 2.4 is the best in some ways.  I've never heard them but it's the last Jim Thiel designed 3-way with an 8" woofer.  I don't know if there's any hard and fast rule but there are definitely advantages to not having huge jumps in driver size.  The 2 series might be an ideal design for a 3-way intended for moderate volume listening.

Spot On! The 8" woofer is excellent, as well as, the passive radiator. Really does make for a pleasant aural experience at any level in a small to medium sized room.  Happy Listening!
