Adapted  from the legendary: Goldmund Mimesis 3 Amplifier circuit, one of the best amplifier ever made. According to Audiogon, not much more to say about Goldmund Mimesis 3 Amplifier other than it's the best of solid state amplifier. What makes it such a legend is its combination of speed, resolution and drive, yet all within the context of a warm, non-fatiguing musicality. It's totally non-cerebral.
