A custom-designed heatsink delivers optimal thermal performance. You can configure the amplifier output as a stereo or mono audio signal, based on your application and setup.

ESS Sabre DAC: The WiiM Amp utilizes an ESS Sabre HyperStream 32-bit DAC (digital-to-analog converter) for high quality sound with a signal-to-noise ratio (SNR) of 98dB and total harmonic distortion (THD+N) of just 0.002%.
