I'm running a Soundstream Van Gogh VGA800.5 amp. I've had it for over 3 years and haven't had any problems with it. My only complaint about it is that the manual that came with the amp is pretty much useless.
I'm not sure how 'old school' it is, but I think they discontinued the line a while ago.
yeah, I miss the old soundstream... the old Reference series of amps.. I remember having a reference 500 pushing a single spl15 monster in the back of my crx... that was back in 95... their old amps could take so much punishment... without a fan, it never once shut down on me.
