One combination I can suggest which really goes against the grain is to try out a solid-state preamp with tube main amps. A few years ago I did just that, with my previous car's audio system! I used a McIntosh MX-401 CD preamp-tuner, with a homebrew tube amp, fed by an old police car's radio/tranceiver switching supply to provide the necessary high voltage. It sounded incredible! Great soundstage, bass, and transient response. The amp I made was done with 6V6 output tubes for perhaps 12 watts / channel, but it had the presence of a much more powerful system. It might be worth a try in a home audio environment.
