Dual CS43198 DAC Architecture

Two Cirrus Logic CS43198 DAC chips work alongside independent amplifier chips to support clear reproduction and responsive musical transients. The dedicated conversion and amplification stages form the foundation of its transparent sound presentation.

Dedicated Power Management

Five dedicated power chips help isolate interference between internal circuits, supporting a quiet background that lets subtle musical details come through.

4.4mm Balanced Output

The 4.4mm balanced output delivers up to 4Vrms and up to 500mW, providing power for more demanding headphones in a portable setup. Actual output depends on the connected load and operating conditions.

Precise Hardware Controls

A physical volume knob offers 100-step adjustment and playback control, keeping everyday listening adjustments close at hand.

Interactive DSP and Parametric EQ

Customize your listening with parametric EQ through a compatible app or web interface. A physical DSP bypass toggle lets you switch between your customized processing and bypassed playback.

Up to 60W PD Passthrough Charging

USB Power Delivery passthrough supports charging at up to 60W, allowing you to power the DAC while charging a compatible phone. Charging performance depends on the connected device, power adapter, and cable.
