Owning four different Sunfire amps and five different Nelson Pass built / designed amps, i would not consider the Sunfire to be in the same league. Mind you, the Sunfire's do have their strengths and can hold their own quite well ( especially if purchased used ), but i would not call them the most revealing or musical. They are however a very solid and reliable work-horse that have no problem cranking out massive amounts of clean power hour after hour. In terms of ultimate performance levels though, Nelson's amps are in a whole different league if you ask me. Sean
