Not sure I would ever be satified with only one pair of speakers, as there may likely not ever be one perfect design for all music. So, I'd have several rooms dedicated to audio, each one fitted with an optimally tweaked system for specific music: one room for jazz; one for female vocals, acoustic guitar, and chamber; one for decently recorded rock/blues; one for poorly recorded rock/blues/metal/punk; and one for classical and opera. And perhaps one room for vinyl, although I'm not sure I'd want to spend the time getting back into that. Oh, and one for Kenny G - the system would consist of a wood (plastic) chipper.
