“The GO bar 10th Anniversary Limited Edition is truly the 'gold standard' among ultraportable USB DAC/headphone amps."
The GO bar is iFi's' top-of-the-line ultraportable USB DAC/headphone amp. 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. Whether you are commuting, working remotely or at your desk, or simply traveling for pleasure, the GO bar is the perfectly portable way to make headphones sound heavenly. Accessories include a leather travel case and a Lightning to USB-C, so there's no need to buy a Camera Connection Kit, plus a USB-C OTG cable and a USB-C to USB-A adapter.
To celebrate their 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-plating and boasts:
The GO bar 10th Anniversary Limited Edition is truly the 'gold standard' among ultraportable USB DAC/headphone amps. Act fast, and place your order because "once it's GOne, it's GOne!"
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 optimize sound quality and ensure a perfect partnership with the GO bar's 32-bit Cirrus Logic DAC chipset. A customized digital filter minimizes pre-echoes and ringing artifacts. 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 and controls to select various sonic tuning options. A column of colored 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 analog circuitry sports a balanced circuit design with an asymmetrical twin-channel output stage. This reduces noise and crosstalk in the signal path by separating the left and right channels completely. 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. Resulting in a stunning design that combines sonic purity with power of:
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:
