The main problem with tube amps, is that insensitive speakers are a pre-requisite ...
Insensitive? I'd have thought the opposite was the pre-requisite.
I think you're wrong. If only because tympani and tecno, harpsichords and 'slightly distorted guitar', saxophone and synth really don't discriminate.IMHO its the type of music you listen to that should decide your amp choice as well as the speakers you use.
