GO Bar portable DAC headphone amplifier

iFi releases the GO Bar, a portable DAC headphone amplifier that's at the forefront of audio tech. Whether you're working at home, commuting, or about to embark on an epic road trip, this portable accessory improves the performance of your headphones. Simply connect it to your tablet, smartphone, or laptop using the USB port and enjoy the unfiltered sound of your favourite tunes with crystal clear clarity.

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.

A customised digital filter minimises pre-echoes and ringing artefacts. Our GMT (Global Master Timing) precision clock system ensures ultra-low jitter.
Ultra-res PCM up to 32-bit/384kHz via USB ​
Native playback up to DSD256​
2x DXD​
Full MQA decoding

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.
At one end is an asynchronous USB-C input and at the other a pair of headphone outputs.
4.4mm fully balanced output – headphones with a balanced cable/connector can benefit from the fully balanced circuitry of the GO bar
3.5mm S-Balanced output – our S-Balanced tech cuts crosstalk and noise by 50% with regular single-ended headphones.

Purity and power
The amp’s design combines sonic purity with power.
475mW into 32 ohms​
7.5V into 600 ohms
​No headphone amp of such a diminutive size can match the GO bar’s ability to drive tricky headphone loads or work with a wider variety of headphones.

The GO bar also incorporates two power tuning technologies:
iEMatch – attenuates power to suit high-sensitivity headphones and IEMs, it removes background noise and increases usable volume range
Turbo – ramps up the gain by 6dB to satisfy more power-hungry headphones"
