THD+N vs. Level at 1 kHz – Headphone Outputs
This graph shows the output of the HPA2™ headphone amp driving a 60-Ohm load at a very high
level (+14 dBu). Even under these conditions, the HPA2™ delivers the full rated performance of
the DAC1. Compare this to the performance of the balanced outputs (see previous graph).
