From the laboratories of EarMen in collaboration with high-end brand Auris Audio comes the TR-Amp, a high quality battery powered DAC with headphone and preamp functionality.

The EarMen TR-Amp boasts an impressive 400mW of maximum power, accomodating almost all known headphone models including those with specific gain requirements.

At the EarMen TR-Amp’s heart is an ES9038Q2M SABRE reference conversion chip which can accommodate PCM 32 bit / 384kHz, native DSD128, and even licensed MQA native hardware rendering.
Texas-Style Amplification

Thanks to the Texas Instruments TPA6120 chip, the TR-Amp’s amplifier section is powered by current-feedback AB architecture which allows listeners to truly hear the music, rather than the amplifier.

The TPA6120 provides up to 128dB of range, high bandwidth, low noise, and a high slew rate to prevent odd-order distortion artefacts.
Cutting Edge Streaming Support

The EarMen TR-Amp’s natural, high resolution sound is now compatible with some of the world’s most popular streaming networks, including Tidal Masters (MQA) over iPhone and Android smart phones, and Qobuz via iPhone, Android, Mac and PC.
