Graph Plot 9 - Headphone Amplifier – THD+N versus Amplitude (DAC2 HGC and DAC2 D

model only)

This plot shows the THD+N performance of the headphone outputs under load. Note that the

THD+N performance of the headphone outputs approaches that of the balanced outputs. The

DAC2 includes Benchmark's HPA2(TM) headphone amplifier. The HPA2(TM) has a near 0-Ohm

output impedance which provides outstanding control and damping of the headphone drivers. The

HPA2(TM) has the voltage and current drive necessary to drive a wide variety of headphones.
