Very interesting! I'm just thinking about trying out tri-amping my NS-2000s. Of course, nowdays it feels as if time alignment etc is important (because it is acheivable), so the whole solution would be expensive using digital filters... Perhaps I'll just ignore today's state-of-the art and go the analogue route instead..
