HPA2™ Headphone Amplifier
(DAC2 HGC and DAC2 D model
only)
The HPA2™is one of the most transparent
headphone amplifiers available. It also is able
to deliver high current and/or high signal
levels, and is well suited for a wide variety of
headphones. The near 0-Ohm output
impedance provides outstanding damping of
headphone drivers. This damping reduces
distortion, and maintains control of the
frequency response.
