D4 DAC and Headphone Amplifier

The D4 combines a high-resolution DAC with a dedicated headphone amplifier powerful enough for demanding full-size headphones.

A balanced internal signal path feeds both 4.4 mm balanced and 6.35 mm single-ended headphone outputs, with three gain settings for matching sensitive and high-impedance designs. Variable rear outputs also let the D4 act as a compact preamplifier for active speakers.
