iFi Audio GO bar Ultraportable DAC/Headphone Amplifier

The DAC section of the GO bar uses a powerful 16-core XMOS micro controller to process the audio data received at the USB input. Our in-house team has programmed the XMOS firmware to optimize sound quality and ensure a perfect partnership with the GO bar‘s 32-bit Cirrus Logic DAC chipset. The GO bar’s smart alloy case sports physical buttons for precise volume adjustment plus controls to select between various sonic tuning options. A column of coloured LEDs provides a handy guide to the format and sample rate of the digital audio currently playing, and whether XBass+ and/or XSpace are engaged.
