Sorry guys, but depending on your definition of "top" it is arguably Bose. $$$$$$$$$.
Actually, in 1956, when Bose was a MIT prof, he had a multidriver (I think it was 24) speaker system set up in the MIT music library that was cutting edge technology for the time.
Apart from that, another vote for Hafler.
