iFi Audio Go Bar

Go, Go, GO!

The GO bar is our top-of-the-line ultraportable USB DAC/headphone amp. Whether you are commuting, working remotely or at your desk or simply travelling for pleasure, the GO bar is the perfectly portable way to make headphones sound heavenly. 

Small. But mighty

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 optimise sound quality and ensure a perfect partnership with the GO bar‘s 32-bit Cirrus Logic DAC chipset.

External Affairs

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.

Balance of Power

Despite its diminutive size, the GO bar’s analogue circuitry sports a balanced circuit design with symmetrical twin-channel output stage. This reduces noise and crosstalk in the signal path by fully separating the left and right channels. This is usually found in larger and more expensive amplifiers.
