I don't like how dry the VH4 is. The Einstein sounded most natural and open compared to the Herbert which was, as im sure you've heard if very "hi-fi" sounding. All these funky adjectives being thrown around but when you hear it, you'll say, yep, that's what they were talking about. Peters are cool amps, I always wanted to try one of those too. Hydra, Chimera, Griffin, all the clips I've heard are awesome.
