iFi GO Bar Kensei: A Portable DAC/Amp That Unleashes Pure Musicality

iFi has launched the GO Bar Kensei, a desktop-quality DAC and headphone amplifier designed specifically for audiophiles seeking both portability and premium audio performance. Named after an honorary Japanese title that means "Sword Saint," this device embodies a commitment to excellence in sound reproduction.

Pricing and Availability

The iFi GO Bar Kensei retails for $449 and is widely available through various online platforms including ifi-audio.com, Amazon, and Sweetwater. Unlike the limited run of the iFi Gold Bar, this model is set to have a longer lifespan in the market according to statements made by iFi representatives.

Design and Build Quality

Unpacking the Kensei presents a delightful experience; it comes encased in an attractive, eco-friendly wooden box. Inside, users will find two braided premium cables (USB-C and USB-C to Lightning, with a USB-A adapter) alongside a sleek leather pouch. Compact enough to fit in a pocket, the Kensei is constructed from Japanese stainless steel and has a surprising heft for its size. The sleek design features chamfered edges that enhance its tactile appeal, although the metal body is prone to fingerprints.

The front of the device boasts an LED panel that displays volume levels, audio formats, frequency information, and sound effects. Users can adjust settings using buttons on the right side, which also houses the IEMatch switch. Audio outputs include a 3.5mm and a 4.4mm headphone jack located at the top, while the USB-C input can support audio up to 32-bit/384kHz.

During operation, the Kensei generates a bit of warmth but remains comfortable to hold. Although it is robust, the material used may scratch or scuff with external use.

Advanced Features

Employing a 32-bit Cirrus Logic DAC chipset, the GO Bar Kensei supports Hi-Res True Native playback across numerous formats including MP3, DSD256, PCM384, and DXD384. The inclusion of full MQA decoding highlights its capability to navigate high-fidelity audio with finesse.

Four digital filters and two analog modes offer nuanced control over sound. They are as follows:

• Bit-Perfect (cyan): This filter is ideal for lossless audio playback, providing a clear and transparent listening experience.
• Standard (red): It lends warmth to vocal tracks, softening any harshness.
• Minimum Phase (yellow): Best for bass enthusiasts, this mode tightens low-end performance while preserving mid-range clarity.
• Gibbs Transient-Optimized (white): This filter upsamples audio, creating an energetic sound profile across frequencies.

The Kensei also accommodates various headphones and IEMs with its IEMatch switch, which adjusts output levels for high-sensitivity devices, alongside Turbo Mode to boost gain for power-hungry headphones. This dual capability allows users to achieve maximum performance without compromising on sound integrity, providing up to 477mW from the 4.4mm output and 300mW from the 3.5mm port.

Like most USB-powered DACs, the Kensei draws power from your source device, which could potentially drain your mobile device more quickly during use. However, while laptops may exhibit less noticeable drain, it's a factor to keep in mind. Notably, the Kensei lacks an internal battery, differentiating it from other models like the iFi GO blu.

Sound Quality Assessment

The sonic performance of the GO Bar Kensei can be described as "ethereal," delivering a full-bodied sound that enriches every listening session. When connected to headphones or IEMs with fine resolution, such as the Sennheiser IE900, the level of detail is remarkable—every nuance in the stereo image comes alive.

Listening to tracks like “Violin Duel” from the Chevalier OST reveals intricate details and the tension created in various musical elements that were previously difficult to discern. Similarly, the richness in the production of Beyoncé's “Texas Hold ‘Em” is brought to the forefront.

The Kensei adeptly manages bass dynamics, showcasing its ability to reproduce deep, resonating tones without losing clarity. When paired with appropriate filters, even lesser quality IEMs like the 1MORE Penta Driver can reveal hidden depths in the audio experience. The K2HD, XBass, and XSpace filters, for instance, work together to expand the listening experience beyond their default tuning.

Competitive Landscape

Positioned as a high-end portable option, the GO Bar Kensei enters a market that includes noted alternatives. The Fiio Q15, for example, comes equipped with an IPS display and Bluetooth capabilities, appealing to users who favor wireless connectivity while maintaining a good selection of sound features.

The iBasso DC-Elite, with a close feature set, also stands as a viable option worth exploring. On paper, it presents a competitive alternative and is often praised for its performance.

Is the GO Bar Kensei Right for You?

Consider the iFi GO Bar Kensei if you value transparent sound and don't require Bluetooth connectivity. It’s a superior choice for those who appreciate DACs that prioritize sound fidelity.

• Pros: Superior sound quality, a good range of features, excellent build quality.

• Cons: Pricy for casual listeners, lacks Bluetooth capability, and no PEQ options.

While the price point may deter casual consumers, the Kensei will resonate well with audio enthusiasts who seek a device capable of both portability and durability, promising years of top-notch listening experiences.
