I second vhiner. I have an 18 year old pair of thiel cs 3.6. I have used 4 different font end with them. Nad pre w/ Acurus a 250 amp, proceed pre and amp 2, classe ssp300 with ca 2200 and finally a classe cp800 with ct 300. IMO the classe is a better sonic match for the thiel which can be bright. With the upgrade of front end It has been hard to justify a speaker upgrade. They just sound very good not perfect but they do so much so well.
