GO bar

USB DAC/zosilňovač pre slúchadlá

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.

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 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.
