Thiel Owners

Pass Int 250 or Gryphon Diablo 300 to drive CS 3.7
Which one has the right sound signature for Thiels ?

You are certainly on the right track for top-tier integrated amps -thieliste
staying tuned as you sort and demo those contenders for your system.

Happy Listening!

Ayre and ARC would be on my short list. Also, Pass, Aesthetix, and Classe. Heed the power ratings per Tom Thiel. You very much want an amp with a decent 4 Ohm rating and 2 Ohm is not overkill.  Maybe take a look at Wes Phillips’ review in Stereophile. I recall he tried two or three amps (but I could be thinking of his cs2.4 review).

jafant are you familiar with the Pass INT 250 ?
Pass is pretty liquid sounding therefore most probably a good match for Thiel.
The INT 250 is doubling it's power down to 2 Ohm.
By the way did you find an amp for your 2.4SE ?

Thieliste, I have used many previous Pass amps and think very highly of them. (I don't know the INT-250). Nelson is a superb designer with values commensurate with driving a Thiel. The simple fact that it is doubling down to 2 ohms speaks clearly to the factors involved in driving a Thiel elegantly.
