Description

GO Bar by iFi Audio, an Ultraportable Premium USB DAC, and the world’s most powerful headphone amp of its size.

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. Connect to your laptop, MacBook, tablet or smartphone or any other digital device with a USB port for sensational sound at home, in the office, or on the move.

Accessories include a leather travel case and a Lightening to USB-C, no need to buy a Camera Connection Kit, plus a USB-C OTG cable and a USB-C to USB-A adapter.

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. Plus the GMT (Global Master Timing) precision clock system ensures ultra-low jitter.

The smart alloy case of GO Bar features 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.

Despite its diminutive size, the analogue circuitry of GO Bar features 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.

The circuitry is packed full of high quality discrete components and special attention has been paid to power supply filtering too, dramatically reducing signal noise introduced through the USB input.

The amplifier design combines sonic purity with power. No headphone amp of such a diminutive size can match GO Bar’s ability to drive tricky headphone loads or work with a wider variety of headphones. This includes power modes for IEM's and power hungry headphones, too.
