iFi Audio Go bar

USB high-resolution pocket-sized and ultra-portable DAC, preamp and headphone amplifier.

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 go.

The circuit is packed with high-quality discrete components and special attention has also been paid to power supply filtering, significantly reducing signal noise introduced by the USB input. This reduces noise and crosstalk in the signal path by completely separating the left and right channels. This is usually found in larger and more expensive amplifiers.

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.

Accessories include a leather travel case and a Lightning to USB-C cable, as well as a USB-C OTG cable and a USB-C to USB-A adapter.
