Take your favourite music on your phone or portable player everywhere you go and don't forget your headphones, but if you really want to get the most out of your sound you should think about using a good headphone amplifier as well.
The iFi Go Bar is the perfectly portable way to make your headphones sound heavenly. Connect them to your laptop, tablet, smartphone or any other digital device with a USB port for sensational sound on the go.
Accessories include a leather travel case and a cable with Lightening to USB-C connectors, plus a USB-C OTG cable and a USB-C to USB-A adapter.
The DAC section of the iFi 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 optimise sound quality and ensure a seamless partnership with the iFi Go Bar's 32-bit Cirrus Logic DAC chipset.
A custom digital filter minimises pre-echoes and ringing artefacts. Our precision GMT (Global Master Timing) clocking system ensures ultra-low jitter.
The iFi Go Bar's powerful processing achieves high resolution PCM up to 32-bit/384 kHz via USB with Hi-Res True Native playback of all music formats from MP3 to DSD256, PCM384 and DXD384. DSD256 and MQA.
It offers four bespoke digital filtering options: Bit Perfect, Standard, Minimum Phase and Gibbs Transient Optimised and two analogue processing modes: XBass+ and XSpace.
The iFi Go Bar's smart alloy housing features physical knobs for precise volume adjustment, plus controls for selecting from a range of sonic tuning options. A column of coloured LEDs provides a handy guide to the format and sample rate of the digital audio being played, and whether XBass+ and/or XSpace are active.
Fully balanced audio output via 4.4mm jack (headphones with a balanced cable/connector can benefit from the iFi Go Bar's fully balanced circuitry. S-Balanced output via 3.5mm mini-jack (S-Balanced technology reduces crosstalk and noise by 50% compared to normal single-ended headphones).
The circuit is packed with high quality discrete components and special attention has also been paid to power supply filtering, drastically reducing signal noise introduced through the USB input.
The amplifier design combines purity of sound with power with 475mW at 32 ohms and 7.5V at 600 ohms. No headphone amplifier of such diminutive size can match the iFi Go's ability to drive difficult headphone loads or work with a wider variety of headphones.
The iFi Go Bar also incorporates two power adjustment technologies: iEMatch (attenuates power to suit high sensitivity headphones and IEMs, eliminates background noise and increases the usable volume range) and Turbo (increases gain by 6dB to satisfy the most demanding headphones).
The 16-core XMOS chip processes audio data received via the USB digital input. This new low latency XMOS microcontroller has greatly improved processing power. Compared to the current generation of eight-core chips, this new 16-core IC offers twice the clock speed (2000MIPS) and four times the memory (512KB), as well as the latest SuperSpeed USB standard.
IFi's in-house digital development team has programmed the XMOS firmware to optimise sound quality and ensure a seamless partnership with the 32-bit Cirrus Logic DAC chipset used in the iFi Go.
Extensive jitter eradication technologies are applied in the digital stage, such as our femto-precision GMT (Global Master Timing) clock and intelligent memory buffering. This represents a total systematic "out-of-the-box" digital solution that solves jitter once and for all.
TDK C0G (Class 1 ceramic) capacitors offer high stability and low losses for resonant circuit applications. Moving ever closer to the theoretical ideal of pure, constant-frequency capacitance, these capacitors reduce capacitor-induced distortion to incredibly low levels.
To celebrate our 10th anniversary, we have created an eye-catching special edition of the iFi Go Bar, limited to 1,000 units, with striking gold plating and a copper chassis for improved build quality and shielding, plus enhanced power filtering.
