The Gunnr is a gaming DAC and headphone amplifier made by Schiit Audio, the American company Jason Stoddard and Mike Moffat founded in 2010, and assembled in Texas. It arrived in October 2024 at USD 229 as the successor to the Hel. The design brings together high output power, analogue soundstage controls, a microphone input and the option of running from one USB-C cable.
Key specs that matter
The Gunnr delivers 2,000 mW RMS per channel into 16 ohms, 1,500 mW into 32 ohms, 800 mW into 50 ohms and 200 mW into 300 ohms. Frequency response runs from 20 Hz to 20 kHz within 0.2 dB. Measured at 2 V, THD stays under 0.0004%, with signal-to-noise above 114 dB A-weighted. Output impedance at the headphone jack is 0.25 ohms. Conversion is handled by an ESS ES9018 DAC, which takes up to 32-bit/384 kHz over USB and 24-bit/192 kHz through the optical input. Inputs are USB-C and optical, and a separate TI ADC serves the microphone. Three gain settings are available, negative gain among them, along with an analogue preamp output. The headphone socket is from Neutrik and volume runs through a custom high-match Alps potentiometer. The box is 145 x 102 x 40 mm and weighs 340 g. Supported hosts are PC, Mac, PS4, PS5, Switch, iOS and Android.
Engineering and use context
Schiit's Soundstage Control occupies two knobs on the front. The first, Width, widens or narrows the stereo image, and turned to the left it blends the two channels. The second lifts or pulls back the band where hearing is most sensitive, home to voices and small cues such as footsteps. Both work in the analogue domain on any source, whatever the surround format, and both can be switched out for a direct signal path. Games consoles and televisions with digital audio output connect through the optical input. With Linear Override the Gunnr can be powered by USB-C alone when used on the move, or by the supplied wall adapter for more power and volume. The gain options cover everything from sensitive in-ear monitors to hard-to-drive headphones. Thanks to its own analogue-to-digital converter, the microphone input handles voice chat as well as podcast-quality recording. Protection circuits guard against over-current from shorts or wrong plugs, overheating and electrostatic discharge. The chassis uses no visible fasteners and carries a solid milled aluminium knob. Buyers who do not need the extra power can order it without the wall adapter for USD 15 less.
Pairing
Headphones of any kind, from sensitive IEMs to demanding full-size designs, can run from the Gunnr, and its preamp output can feed a pair of powered desktop speakers.
Alternatives
For a more compact desk unit, Schiit offers the Fulla, which also combines a USB DAC, a headphone stage and a microphone input.
