I still have 7 tube combos. In addition, I use two different frfr setups with my FM-3, as well as a QSC power amp into a pair of JBL G730s from the late 80s. Lastly, I also can pair my FM-3 with a Mesa 50/50 tube power amp and two Mesa 1-12" cabs.
They all sound great, but I can get a much wider range of sounds at a much wider range of volumes with the FM-3 doing the dsp and the amps/cabs/frfrs just providing volume. I still love plugging into a TopHat, Mesa Maverick, NMV Marshall, or 5e3 when I can get 'em breathing, but none of this is a religion to me; the end justifies the means IMO when it comes to playing music. That said, if I were limited to one unit/tech (the "desert island" scenario), I'd take an FM-3 and an EV or Yamaha coax stage monitor over any tube rig I've played in 60 years of doing so. Would've killed for this stuff in the late 60s.
