I am putting a relatively new CODA #8 amp that kills on the hard to drive Thiel CS3.7 up for sale. It is 150 | 300 | 600 @ 8 | 4 | 2 with the first 18 watts in Class A. You could get it reconfigured at the factory for less Clas A power and much more Class AB power. That is V1, V2, or V3. Mine is V1 with 18 Class A watts.
