It may not be an obvious step, so what more are you craving? I still own my Thiel CS 3.6 speakers, but my musical tastes shifted as I got older seeking out a more relaxed sound. Now, I have 300b amps and Horning Speakers, so I kind of flipped 180.
What's funny, is just before I clicked on your post, I was thinking, what good value solid state amps could I pair with my Thiels as a second system? You see, I love my new setup for the jazz and such, but sometimes I miss cranking it up for rock n' roll with the Thiels.
