I've never been much of a Marshall player, for no particular reason, but I know someone who collects ancient / original Marshall heads and cabs. I once plugged into 4 different setups of his, I wanna say the JCM 100 was my favorite. They were all from the early 1970s. I've yet to hear a modern-made Marshall head that rivals the oldies. Anyway, regardless of the brand or date, I think we all agree tubes are better than solid-state.
