iFi Audio GO bar, iFi audio's premium ultraportable USB DAC/headphone amp. Wherever you find yourself—whether commuting, working remotely, at your desk, or traveling for leisure—the GO bar is the ultimate solution for elevating your headphone experience on the go.

Effortlessly connect it to your laptop, MacBook, tablet, smartphone, or any other digital device with a USB port, and immerse yourself in sensational sound whether you're at home, in the office, or on the move.

The GO bar comes with convenient accessories, including a leather travel case, a Lightning to USB-C cable (eliminating the need for a Camera Connection Kit), a USB-C OTG cable, and a USB-C to USB-A adapter.

Small yet powerful, the GO bar features a DAC section equipped with a robust 16-core XMOS microcontroller to process audio data from the USB input. Our expert team has fine-tuned the XMOS firmware to optimize sound quality and ensure seamless compatibility with the GO bar's 32-bit Cirrus Logic DAC chipset.

To minimize pre-echoes and ringing artifacts, we've implemented a customized digital filter. The GMT (Global Master Timing) precision clock system guarantees ultra-low jitter for a pristine audio experience.

Key Features:
- Supports ultra-res PCM up to 32-bit/384kHz via USB
- Native playback up to DSD256
- 2x DXD
- Full MQA decoding

Tailor the sound to your preferences with four bespoke digital filtering options:
1. Bit Perfect: No digital filtering, no pre or post-ringing
2. Standard: Modest filtering, modest pre and post-ringing
3. Minimum Phase: Slow roll-off, minimum pre and post-ringing
4. Gibbs Transient Optimized: Minimum filtering, no pre-ringing, and minimum post-ringing

Additionally, two analogue processing modes are available:
- XBass+: An analog bass boost that restores lost bass response for accurate reproduction of the original
- XSpace: A holographic sound field that opens up your music, providing the spaciousness of a live concert

The GO bar's smart alloy case features physical buttons for precise volume adjustment and controls to select sonic tuning options. A column of colored LEDs serves as a visual guide, displaying the format, sample rate of the currently playing audio, and whether XBass+ and/or XSpace are active.

At one end, you'll find an asynchronous USB-C input, while the other end houses a pair of headphone outputs:
- 4.4mm fully balanced output: For headphones with a balanced cable/connector, taking advantage of the GO bar's fully balanced circuitry
- 3.5mm S-Balanced output: Our S-Balanced technology reduces crosstalk and noise by 50% when used with regular single-ended headphones

Despite its compact size, the GO bar incorporates a balanced circuit design with a symmetrical twin-channel output stage. This design effectively minimizes noise and crosstalk by separating the left and right channels, a feature typically found in larger, more expensive amplifiers.

The circuitry is meticulously constructed with high-quality discrete components, and particular attention has been given to power supply filtering. This attention to detail significantly reduces signal noise introduced through the USB input.

Experience sonic purity and power with the GO bar's impressive specifications:
- Output Power: 475mW into 32 ohms, 7.5V into 600 ohms
- No other headphone amp of such compact size can match the GO bar's ability to drive challenging headphone loads or accommodate a wide range of headphones.

The GO bar also includes two power tuning technologies:
- iEMatch: Attenuates power for high-sensitivity headphones and IEMs, eliminating background

noise and expanding the usable volume range.
- Turbo: Increases the gain by 6dB to satisfy power-hungry headphones.

Please note that the GO bar may not be compatible with iPhones up to and including 6S when the phone battery is low (<30%).
