■ The MHA150 contains the same feature set as the
critically-acclaimed MHA100 but with a new digitalto-analog converter (DAC) that adds support for DSD
and DXD files to give you access to the latest in
digital music performance.
■ Utilizes our Autoformer technology to produce three
headphone impedance ranges of 8-40, 40-150 and
150-600 ohms so every headphone will produce the
best possible personal listening experience.

SACDs when paired with the McIntosh MCT450
SACD/CD Transport.
