The Burson HA-160D is a well-made product. It was my reference amplifier for a long time.

Its most attractive feature (main reason for my purchase) is the internal DAC, which permits direct connection of the unit to
the digital output of your source of choice, and thus bypassing the-less-than-optimal analog stages of cheap CD players or soundcards.

It delivers fairly good sound through its analog amplifier stages (headphone amp stage), however at times I felt that it had
difficulty driving the big Hifiman HE-6.
Its volume control unit is not a good solution at all.
The attenuation is achieved through manual switching of discrete resistors in the signal path by a rotary switch.
Depending on the headphone used, at times (unfortunately quite often), it was either too loud or too quiet, as it was impossible
to find an appropriate intermediate setting for the volume control between the two adjacent discrete attenuation settings.
I don't believe in the discrete -db attenuation Volume-Control for headphone amps.
For usual speaker amplifiers they are wonderful.
Headphone listening is very different and more intimate than listening through speakers.
It is sometimes necessary to continuously adjust the volume in very small increments,
not the big jumps the discrete-type attenuators provide.
Recent comparisons to other pure analog amplifiers made its few flaws deadly apparent.
Unfortunately the price tag also limits the attraction. Although I don't believe the price is set too high for the
technology it provides, there are other offerings that are cheaper (but without the internal DAC) and deliver superior sonics.
Nonetheless, a well engineered and a fairly good sounding product for anyone who is considering a possible purchase.
