Premium USB DAC. World’s most powerful headphone amp of its size.
To celebrate our 10th anniversary, we’ve created an eye-catching special edition of the GO bar.
Limited to 1000 pieces, the 10th Anniversary Limited Edition GO bar is smothered in show stopping gold-plate and boasts:
The GO bar 10th Anniversary Limited Edition is truly the ‘gold standard’ among ultraportable USB DAC/headphone amps.
Act fast. Pre-order yours now from your local iFi dealer.
Once it’s GOne, it’s GOne!
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 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. Our GMT (Global Master Timing) precision clock system ensures ultra-low jitter.
Four bespoke digital filtering options:
Two analogue processing modes:
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.
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.
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 amp’s design combines sonic purity with power.
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:
*Please note that the GO bar may not work with iPhones up to and including 6S when the phone battery is low (<30%).
