Compact desktop DAC and headphone amplifier

The BFKK FX-Audio DAC-X6 is a desktop digital-to-analogue converter with an integrated headphone amplifier. It accepts USB, optical and coaxial digital sources and provides both RCA line-level outputs and a front-panel headphone jack. The unit is designed to drive headphones from 16 to 300 ohms without adding colouration.

Passive cooling and external 12 V supply

The aluminium chassis relies on passive heat dissipation, so there are no moving parts to generate noise. Power is supplied through an external DC 12 V adapter, keeping the internal circuitry isolated from mains-borne interference. Typical power draw remains modest during normal listening sessions.

Brushed aluminium front panel with relay protection

A brushed aluminium front panel carries a large volume knob, a power toggle and a three-way input selector for quick source switching. The rear panel offers Type-B USB, Toslink optical and coaxial inputs plus dual RCA pre-outs for connection to a power amplifier or active speakers. A built-in relay protects connected headphones and speakers from turn-on transients, and the socketed op-amps can be swapped for alternative units.

Questions about this item

How do I connect the DAC-X6 to my computer and switch between the USB, optical and coaxial inputs?

Use the rear Type-B USB port for the computer and the Toslink or coaxial sockets for other sources; the front 3-way toggle selects the active input.

Which op-amp chips can I swap in later and how do I do it?

The socketed LM4562NA op-amps are user-replaceable; lift the old chips and press in compatible dual op-amps.

At what sample rate does the USB input stop accepting higher-resolution streams?

USB is limited to 24-bit 96 kHz, while optical and coaxial accept up to 24-bit 192 kHz.
