Desktop DAC with headphone amp

The BFKK DAC-A2 is a desktop digital-to-analog converter that includes a built-in headphone amplifier. It accepts audio from a computer via USB or from other sources through optical and coaxial S/PDIF inputs. The unit is powered by a 5 V DC supply and provides both RCA line outputs and a 3.5 mm headphone jack. Bass and treble controls are provided on the front panel for tone adjustment.

Suits stereo listeners needing tone controls

This device suits users who want to connect a computer or digital transport to powered speakers or an external amplifier while also driving headphones. The front-panel bass and treble knobs allow quick tonal changes without software. Buyers who require balanced headphone outputs, higher-impedance drive beyond 200 ohm, or wireless streaming should look at other products.

Drives 16 to 200 ohm headphones

The internal TPA6120 and OP275 amplifier chips comfortably drive headphones from 16 ohm up to 200 ohm. USB input supports 24-bit/96 kHz playback, while optical and coaxial inputs accept 24-bit/192 kHz signals. The RCA outputs feed powered speakers or a separate amplifier. Headroom diminishes with very low-sensitivity or very high-impedance loads beyond the stated range.

Questions about this item

What headphone impedance range does the built-in amplifier support?

The internal headphone amp chip drives loads from 16 ohm up to 200 ohm, covering most common desktop and portable headphones.

Can I keep my existing powered speakers connected through the RCA outputs while using the headphone jack?

Yes, the RCA line outputs remain active so you can feed powered speakers or a separate amplifier at the same time as the 3.5 mm headphone output.

Which LED or display confirms the DAC is receiving a 24-bit 192 kHz stream over optical or coaxial?

The unit has no sample-rate indicator; you verify the 24-bit 192 kHz lock by checking the source device's audio settings or playback software.
