iFi Audio - Go bar - Ultraportable Premium Headphone USB DAC

Best, bar none! Premium USB DAC. World’s most powerful headphone amp of its size.

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.

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

The DAC section of the GO bar uses a powerful 16-core XMOS microcontroller 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.

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.

Despite its diminutive size, the GO bar’s analog circuitry sports a balanced circuit design with a 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.

A customised digital filter minimises pre-echoes and ringing artefacts. Our GMT (Global Master Timing) precision clock system ensures ultra-low jitter.

Four bespoke digital filtering options:

• Bit Perfect – no digital filtering, no pre or post ringing
• Standard – modest filtering, modest pre and posting ringing
• Minimum Phase – slow roll-off, minimum pre and post ringing
• Gibbs Transient Optimised – minimum filtering, no pre-ringing and minimum post ringing

Two analogue processing modes:

• XBass+  – an analog bass boost to ‘add back’ lost bass response for a more accurate reproduction of the original
• XSpace  – a holographic sound field to open up your music to give you the spaciousness of a live concert
