I would go for a Tandberg 3026A 0r 3006A. Both of these amps are solid state but have a reputation for sounding "Tube like" as far as solid state equipment goes. Tandberg's have a reputation for being quality built. Both of those amps have 150 watts per side and are conservatively rated at that. I bought a pair of Tandberg 3009A monoblocks from a guy who had a set of Thiel's, he said the combination sounded great.
