This is something I've often wondered when considering power amp/preamp rigs. What change would there be in tone if you used a power amp that isnt specifically made for bass amplification (such as QSC or Crest Audio) or a power amp such as the Epifani XP-L90 or Ampeg SVP-1600, which are pretty much bass specific? Is it all essentially the same thing? Now I know there would be a rather major difference if you used a tube power amp but would all the solid state stuff be mostly the same? Thanks a lot for any help!
