What is the best solid state amplifier you have ever heard?

Pass Xa.8 (w Wilson Sabrina)
Fistwatt J2

I have also a Nagra 300i (300b tubes). i300 is sounds similar to the two Pass Amps, but Xa.8 is materially stronger

Other strong contenders

- Accuphase a46 (et al)
- Bryston (too cold sounding)
- Firstwatt F5 turbo very cool
