This unit has a two-amplifier structure based on the design concept of
luxury models, comprising a current feedback voltage amplifier using
the HDAM
the HDAM
®
SA2 and a feedbackless Darlington power buffer. This
allows higher speeds without creating dynamic strain in response to
impedance changes in the headphones.

Isolation design
To prevent audio quality from degrading due to noise from external
devices when this unit is connected to external devices such as
computers, the ground circuit for the USB input interface device is
isolated from the audio circuit.
