Actually Vitus Audio Class A amplifiers are quite different to other SS amplifiers.I haven’t heard these big Goldmund amps but I heard almost all big Goldmund monos over the years. None of them sounding good though. If I have to describe Goldmund sound cardboard pops in my mind. I prefer Vitus or Absolare SS instead but that’s just me. If you’re switching from Kondo or another top SET amp to Goldmund or Gryphon that means you shouldn’t have Kondo in the first place. It takes time to appreciate SET sound. Again it’s just my opinion.
I think the sound of Vitus is also different to other Class A SS amplifiers like Pass Labs or Gryphon.
Hans Ole Vitus spend 8 years to design SM100 100w class A amplifier.
