Compact DAC and headphone amplifier

The FX-Audio DAC-X6 is a desktop digital-to-analogue converter and headphone amplifier aimed at listeners who want cleaner sound from a computer, TV set-top box or disc player. It accepts USB, optical and coaxial inputs and drives both RCA line outputs and a 6.35 mm headphone jack simultaneously. The volume control affects only the headphone output.

24-bit 96 kHz decoding with op-amp headroom

The CS4398 DAC chip handles 24-bit 96 kHz streams and delivers 2 V RMS line-level output. Headphone power scales from 90 mW at 600 Ω to 910 mW at 32 Ω, covering most dynamic and planar models. The relay protection circuit guards speakers and headphones during power-on and power-off transients.

Socketed op-amps and relay protection

The signal path uses OPA2134PA, 6120A2 and OP275G op-amps in sockets so they can be swapped for different tonal signatures. A 12 V DC supply is included with EU or US plug options. The aluminium chassis measures 146 x 98 x 35 mm and runs cool without a fan.

Questions about this item

Will the 2V RCA line-level output drive my older power amp without a pre-amp?

Yes, the fixed 2V RMS RCA output feeds any power amp or active speaker directly; volume is controlled only on the 6.35 mm headphone jack.

How can I confirm the CS4398 DAC is decoding 24-bit/96 kHz from my PC-USB connection?

Play a 24-bit/96 kHz test file and verify the optical/coaxial LEDs stay off while the USB LED lights, showing the SA9023 receiver has locked to the high-res stream.

Which cables and adapters are included so I can connect headphones and speakers right away?

The box contains the DAC-X6, a 12 V/1 A power supply, a USB cable, and a 6.5 mm to 3.5 mm headphone adapter; RCA and optical/coaxial cables are not supplied.
