The iFi GO Bar Portable DAC & Headphone Amplifier is an ultraportable and powerful device designed to enhance your audio experience wherever you go. This device is ideal for those who are always on the move and are looking for a way to enjoy high-quality sound from their headphones. The GO Bar is small in size but mighty in performance, making it the perfect accessory for your laptop, tablet, smartphone, or any other digital device with a USB port.

The GO Bar's powerful 16-core XMOS microcontroller processes the audio data received from the USB input, producing sensational sound that is optimized for quality. This device is equipped with a 32-bit Cirrus Logic DAC chipset and a custom digital filter that minimizes pre-echoes and ringing artefacts. The GMT (Global Master Timing) precision clock system ensures ultra-low jitter, resulting in pure and clear audio playback.

This portable DAC & Headphone Amplifier supports ultra-res PCM up to 32-bit/384kHz via USB, native playback up to DSD256, and full MQA decoding. It also offers four bespoke digital filtering options, including Bit Perfect, Standard, Minimum Phase, and Gibbs Transient Optimized. Additionally, there are two analogue processing modes, XBass+ and XSpace, which enhance the bass and add a holographic sound field to your music, respectively.

The GO Bar has a smart alloy case with physical buttons for precise volume adjustment and controls for selecting various sonic tuning options. The coloured LED column provides a handy guide to the format and sample rate of the digital audio playing and whether XBass+ and XSpace are engaged. The device has an asynchronous USB-C input and a pair of headphone outputs, including a 4.4mm fully balanced output and a 3.5mm S-Balanced output.

The GO Bar's balanced circuit design with symmetrical twin-channel output stage reduces noise and crosstalk, making it possible to enjoy high-quality audio even in noisy environments. The device's circuitry is packed with high-quality discrete components and has special attention paid to power supply filtering, which dramatically reduces signal noise introduced through the USB input.

The amp's design combines sonic purity with power, producing 475mW into 32 ohms and 7.5V into 600 ohms. The GO Bar also has two power tuning technologies, iEMatch and Turbo, which help to optimize power for high-sensitivity headphones and power-hungry headphones, respectively.
