After owning several integrated amps in the 60's & 70's (Pioneer; Sansui; Kenwood), I moved into separates with a Bruston 4B in the 80's. I've also owned a Musical Fidelity A-5 and auditioned Classe and Parasound JC-1's and my favorite SS amp is the one I own and use now--the Modwright KWA-150.

Power: 150W @ 8ohms; 250W @ 4 ohms; 450W @ 8 ohms bridged mono; 650W @ 4 ohms bridged mono. ALL power ratings at .05% THD!
Noise Floor: -100dB (Unweighted)
Bandwidth: 10Hz - 100Khz (+0, -1dB)
I have found this amp to do a great job of combining the strengths of SS and tubes in a SS amp. Great bass slam and control with exceptional midrange and soundstage. Totally non-fatiguing.
