One of my all time favorite sounding speakers are the Thiel Audio Model CS2 speakers. A number of reasons why:
1) Great soundstage and depth for the Thiel Model CS2 speakers.
2) Small footprint but can fill a large room. They don't take up much space but can fill a room.
3) Of all the Thiel Audio speakers (which I've owned a dozen different models over the last 30 years) the Thiel CS2 speakers keep on giving great sound regardless of electronics. They sound great both on solid state or tube setups.
4) Fairly efficient speaker and very versatile speaker, such as reason #3.
5) They don't make them like they use to. Meaning the Thiel CS2 speakers are built like a tank and were affordable back in the day $1690 pr. in 1988.
6) Dollar for dollar almost impossible to beat in sound, build and reliability.
7) Do yourself a favor and go pick up a pair of Thiel CS2 speakers and you will be very happy that you do so.
