Pal, I see you're getting some Starsound speakers. Before I started to consider getting a tube amp I think I'd inquire about the speakers efficiency, its nominal impedence, and its minimum impedence all of which are very important in selecting a good matching tube amp. FWIW. Can't comment of the Butlers as I've never heard of them.
Butler amps?
Any opinions on Butler amps? I am considering a 2250 amp but would like some feedback on the amp. It looks like an interesting tube design with 250 watts per channel.
