Kabir,
Based on your comments I pretty much doubt you were considering a Spectron amp in the first place. Nobody who's considering purchasing a high quality piece of audio gear would make a decision in the time it takes to read a sentence. It takes serious thought and analysis to find out if a particular amp will be good for your system.
Spectron is one of the few audio companies I've been completely happy to deal with. I've called or emailed other companies with issues and I most of the time find their help and advice very superficial and brief. I am very proud to have such great amps, and even prouder of their excellent performance. Spectron is the only company I know that gives warranties issues a priority over production.
Some of the comments in this thread are really uncalled for. I'm sure there is a very good reason why more information about the SE MK II hasn't been posted yet. It takes time to translate the inner workings of electrical engineering into a language that most people can understand, to name one possible reason. Maybe the web-master still working on it, to name another reason. I really don't know. But what I know is that I've really enjoyed dealing with Spectron, and Simon has been extremely helpful in helping me with the rest of my system. I'm not saying that other companies are not helpful, but that Spectron seems to try harder than other companies at making sure that their amps work the best in your system.
Best Regards,
