Burson HD Audio DAC
While most of the marketing spin centres on the DAC chip,
the output stage is in fact one of the critical stage in
any audio DAC design. It is not getting the air time that
it deserves because a properly designed ouput stage is not
simple, and the concept is harder to sell to a customer
compared to a DAC chip model number.
After the digital signal (0s and 1s) is converted by the
DAC chip into stereo signals, an important LP (low pass)
stage is need to reconstruct the analog signal from the
rectangular pulses from the DAC output Any distortion and
signal loss during this conversion stage is irreversible.
Unfortunately, due to the lack of customer awareness of
the output stage, this is where most audio companies cut
their costs, and it is common to see a output stage
designed around a cheap IC opamp.
The HA-160D has a fully discrete output stage that is
independently powered. It has a high slew rate and fast
recovery time operate in pure Class A the HD Audio DAC
ensures the highest level of signal preservation. The
result is higher resolution audio playback, with a
completely transparent sonic signature consistent with our
ideals.
