iFi GO bar Kensei Review: Premium DAC/Amp Redefining Mobile Audio Quality

The iFi GO bar Kensei is aptly named after the Japanese term for "Sword Saint," reflecting the meticulous craftsmanship that iFi has infused into this standout product. Catering to the sophisticated audiophile, this device goes beyond mere specifications to deliver an experience of sound that resonates deeply with music lovers.

Pricing and Availability

Retailing at $449, the iFi GO bar Kensei is available for purchase on ifi-audio.com, Amazon, and retailers like Sweetwater. Unlike the limited edition iFi Gold bar, the Kensei is anticipated to have a more sustained market presence, as confirmed by an iFi representative in discussions on dedicated audio forums.

Design and Build Quality

Unboxing the Kensei presents an experience worthy of its price tag. Shipped in an eco-friendly, intricately carved wooden box, the package includes high-grade braided cables—a USB-C, a USB-C to Lightning, and a USB-A adapter—as well as a leather pouch. Its compact design, comparable to a USB flash drive, is constructed from Japanese stainless steel, giving it a solid heft; however, it is somewhat susceptible to fingerprints and minor scratches.

The device is elegantly designed with chamfered edges and branded etching, but it’s the multimedia interface that stands out. Its face features LED indicators for volume, audio format, frequency, and sound effects, while the user-friendly right side hosts the volume and settings buttons alongside an IEMatch switch for enhanced compatibility. Earphone outputs are conveniently located on the top, featuring both 3.5mm and 4.4mm options, while a USB-C input supporting up to 32-bit/384kHz audio is located at the bottom.

Key Features

The Kensei employs a top-tier 32-bit Cirrus Logic DAC chipset, delivering Hi-Res True Native playback for a range of music formats, from standard MP3s to high-fidelity DSD256 and PCM384. Notably, it also includes full MQA decoding. Premium capacitors contribute to a clean signal and minimize distortion, making for a well-rounded audio performance.

Highlighting its versatility are four digital filters and two analog modes. Users can choose between:

• Bit-Perfect (cyan): Provides unaltered, high-resolution audio that reveals detail.
• Standard (red): Delivers smooth, warm vocals.
• Minimum Phase (yellow): Prioritizes bass without sacrificing mids.
• Gibbs Transient-Optimised (white): Energizes audio through upsampling.

The IEMatch switch effectively manages output for both high-sensitivity in-ear monitors (IEMs) and power-hungry headphones, with impressive output levels reported at 477mW from the 4.4mm balanced output, and 300mW from the 3.5mm output.

However, it's worth considering that the Kensei draws substantial battery power from connected devices, particularly smartphones and tablets. Unlike some other portable DACs, it lacks an internal battery, which could lead to quicker battery drainage during extended use.

Sound Quality Observations

When it comes to performance, the Kensei's audio output is strikingly transparent yet full-bodied. Pairing it with higher-end gear, such as the Sennheiser IE900 IEMs, reveals a depth and clarity previously masked in less capable setups. Listening to tracks such as “Violin Duel” from the Chevalier OST showcases intricate details—the friction of strings, dynamic range, and subtle shifts in expression.

Even in bass-heavy tracks, the transparency becomes apparent. While the IE900 may not be primarily bass-oriented, activating iFi's XBass filter allows for an enjoyable experience across genres, as evidenced by tracks like Skrillex’s “Mumbai Power.” The listening experience is enriched further through the application of different digital filters, tailoring each session to the connected audio hardware.

Competitive Landscape

The GO bar Kensei distinguishes itself with unique aesthetics and premium packaging, setting it apart from competitors in the high-end DAC/Amp market. Alternatives like the Fiio Q15 and iBasso DC-Elite offer viable options in this price range, each bringing different feature sets, including Bluetooth capabilities and onboard displays, which may cater to various user preferences.

Should You Invest in the iFi GO bar Kensei?

Consider the Kensei if you:

• Prioritize audio transparency without the need for Bluetooth.
• Appreciate finely tuned DACs designed for an audiophile experience.
• Prefer straightforward settings over parametric EQ functionalities.

You might want to reconsider if you:

• Have budget constraints.
• Require Bluetooth connectivity.
• Value parametric equalization capabilities.

The Kensei promises a rich audio experience that resonates with dedicated music enthusiasts. While it positions itself as a luxury item for casual listeners, its build quality and sonic performance deliver substantial value for discerning users seeking a powerful portable DAC/Amp.
