High-end audio has always been a costly hobby, with enthusiasts often spending significant amounts to achieve the best possible listening experience. Unfortunately, the best modern Android phones fall short in delivering top-notch audio due to the lack of powerful DACs and headphone jacks. The iFi GO Bar, a compact USB DAC and headphone amplifier, addresses this issue, providing high-end audio quality on the go. Priced at £329, it represents a considerable investment but promises a superior auditory experience.
Design and Build Quality
The iFi GO Bar is impressively compact, measuring just about the size of a pack of gum. Despite its small size, it does not compromise on performance. The GO Bar can drive high-impedance headphones as effectively as a dedicated desktop amp/DAC setup while also supporting high-resolution audio files.
The right side of the device houses all the controls, including three buttons and a three-way slider. The buttons manage XBass+/XSpace toggling and volume adjustments, while the slider controls the IEMatch modes. These modes are essential for using sensitive in-ear monitors, reducing noise, and allowing for finer volume control. This feature is particularly useful given the GO Bar’s power output, which can otherwise overwhelm sensitive IEMs.
Unlike other portable DACs that incorporate displays, the GO Bar opts for a simpler interface using nine LEDs. These LEDs indicate bitrate, MQA decoding, and other settings, providing a straightforward and intuitive user experience.
Included with the GO Bar are OTG cables compatible with Android, iPhone, or computer, as well as a leather carrying case. The case includes a belt loop for easy transport but does not allow for the device’s use while it is inside, meaning users will have to carry the GO Bar separately when in use.
Software and Usability
External DACs often face compatibility issues with Android devices due to inconsistent support from manufacturers. However, apps like USB Audio Player Pro (UAPP) can facilitate the switch to a USB DAC for audio processing, offering a solution for those seeking the highest resolution playback.
One downside of the GO Bar is its power consumption, which can significantly impact your phone’s battery life, especially when driving high-impedance headphones. This isn’t a dealbreaker, but users should be prepared for increased battery drain. When using less demanding in-ear monitors, the additional battery consumption is less severe.
Audio Performance
The iFi GO Bar excels in delivering high-quality audio, supporting demanding high bitrates and large DSD files typically reserved for dedicated audio players. This performance makes the GO Bar comparable to entry-level desktop setups, offering ample power for both entry-level and more demanding audiophile headphones.
The GO Bar includes features like turbo mode, which provides extra power for high-impedance headphones. Activating turbo mode is simple, requiring a simultaneous press of the volume up and down buttons. Additionally, the XBass+ feature enhances bass response, while XSpace expands the soundstage, providing more separation between instruments and vocals. These features, combined with the GO Bar’s crystal clear audio and neutral coloration, deliver an immersive listening experience.
Both the 4.4mm balanced and 3.5mm S-Balanced jacks offer clean, interference-free audio. The GO Bar’s single set of DAC and amp chips ensures consistent output across both jacks, unlike some DACs that only utilize dual chips for balanced outputs.
Final Verdict
The iFi GO Bar is an outstanding choice for those looking to enhance their mobile listening experience without resorting to a separate audio player. It supports high-impedance headphones, top-tier audio file formats, and delivers exceptional sound quality in a remarkably compact size. Though it comes at a premium price, its unparalleled audio performance and portability make it a valuable investment for serious audiophiles.
Pros:
- Ultra-portable with high impedance headphone support.
- Supports high-resolution audio files, including FLAC, PCM, DSD, and full MQA decoding.
- Simple and intuitive interface with LED indicators.
- Powerful enough to drive demanding headphones.
- Includes useful features like XBass+, XSpace, and IEMatch.
Cons:
- High power consumption impacts phone battery life.
- Android compatibility issues may require additional software.
- Pricey compared to other portable DACs.
Conclusion
The iFi GO Bar is the ultimate portable DAC for audiophiles who demand desktop-quality audio on the go. Its ability to drive high-impedance headphones, support for high-resolution audio files, and compact size make it a standout choice. While it may not be the cheapest option on the market, its superior sound quality and features justify the investment for those serious about their mobile listening experience.
