I think you're wrong. If only because tympani and tecno, harpsichords and 'slightly distorted guitar', saxophone and synth really don't discriminate.
If you're not careful you end up with a system that only plays noodley jazz, nice for 30 seconds but completely pointless.

Maybe its just me. When I play rock say Moody Blues or Jethro Tull on the Maggies it just does not do justice to the dynamics required to feel the power of the music. However when played through the Pipedreams its another ballgame.
I prefer rock and large scale music with the Pipedreams and jazz and vocals through the Maggies.
The pipedreams are driven by SET 211 amps and the Maggies by S/S go figure. Both use a tubed pre and source is tubed CDP and Linn TT.
Just my experience. it appears to me that the music and speakers determine the amp choice. Just my opinion.
