Hello cortw1965!
I have the Thiel CS 2.4 and have been very happy driving them with a Bryston 3BST which is now 20 years old and still going strong.
Bryston amps are generally a good match for Thiels.
Most important thing is to keep in mind that speakers like the CS 2.3 require a quality high current amp that can handle the fact that Thiel speakers impedance will often drop considerably below their nominal 4 ohm rating. As per Stereophile the CS 2.3 drops down to 2 ohms at 450Hz ... so need to make sure the amp is stable down to 2 ohms.
