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 and
accurate imaging of every instrument and vocals
at complex and high energy passages
.
You can feel the drum
sticks hitting the cymbals and the piano hammer hitting the
strings'  

.
