M400 Audiophile Mosfet, Dual symmetrical differential power amplifier

Direct Signal Purist Concept.
M400 uses  2 pairs  2SK1058/J162
per channel produced by Renesas designed specifically for audio
application. Unlike conventional amplifier, it only require 2 stage
signal amplification to drive these mosfets, hence very natural sounding.
