The Ultimate GO bar — forged for masters of audio, with K2HD processing and refined power/clock design.
The iFi GO bar Kensei is a customized portable decoder and headphone amplifier “integrated machine” built to deliver a truly high-end listening experience anywhere. Inspired by the Japanese term “Kensei” (Sword Saint), it represents iFi’s pinnacle refinement of the GO bar range—focused on purity, balance, and musical realism. With Japanese audio processing technology K2HD, an upgraded power supply, and improved clock circuitry, Kensei elevates headphones and IEMs with richer harmonics, improved detail, and a more lifelike presentation—perfect for commuting, remote work, and travel.
GO bar Kensei is engineered like a legendary blade—meticulously refined to reveal the true essence of your music. By combining advanced Japanese processing (K2HD) with improvements to the power supply and clocking, the Kensei delivers a cleaner, more stable signal path and a more emotionally engaging sound.
Even when digital recordings measure “perfect,” they can sometimes feel emotionally flat. Developed by engineers at Victor Studio, K2 Technology / K2HD was created to restore rich, natural harmonics and an organic sense of realism to digital audio—bringing recordings closer to the feeling of the original master.
“K2 Technology” and “K2HD” are registered trademarks of JVCKENWOOD Corporation.
Listen the way you like with four bespoke digital filters and two analogue processing modes, each designed to complement different genres and preferences.
The DAC section uses a powerful 16-core XMOS micro controller to process audio data from the USB input. iFi’s in-house firmware is tuned to optimise sound quality and to pair perfectly with the 32-bit Cirrus Logic DAC chipset. A customised digital filter reduces pre-echoes and ringing artefacts, while iFi’s GMT (Global Master Timing) precision clock system helps deliver ultra-low jitter performance.
Crafted with Japanese stainless steel for maximum rigidity, the GO bar Kensei is incredibly compact (65 x 22 x 13.2 mm)—about the size of a USB flash drive—making it a perfect portable companion for your phone, tablet, or MacBook Pro. With USB-C plug-and-play convenience, you can elevate your headphone setup anywhere.
Connect via 3.5mm S-Balanced or 4.4mm Balanced headphone outputs. iFi’s exclusive 3.5mm S-Balanced design helps reduce crosstalk and noise compared with regular single-ended outputs, delivering a cleaner, more separated sound even with standard 3.5mm headphones.

GO bar Kensei is akin to a legendary sword meticulously forged for a Kensei. Embodying the dedication of a master swordsmith, we focused on purity, balance, and refinement to reveal the true essence of your music.
Featuring cutting-edge Japanese audio processing technology: K2HD, and improved power supply and clock circuitry, the Kensei represents the pinnacle of our journey of refinement in the GO bar range.
Whether you’re commuting, working remotely, or traveling for pleasure, the GO bar Kensei offers a perfectly portable solution to elevate your headphone experience to heavenly heights.
Kensei is a Japanese term that translates to “Sword Saint” in English, a title granted to the elite few who elevate the craft and artistry of swordsmanship beyond even that of the finest swordmasters.
Despite their pristine clarity, digital recordings sometimes seem emotionally flat and lifeless.
Engineers at the prestigious Victor Studio, troubled by the discernible lack of emotion between their original masters and digital sub-masters, embarked on a quest for a solution.
They meticulously compared countless finished recordings with the copy recordings by ear, relying on their instinctive feel and their human expertise.
Their solution; K2 Technology*.
The K2 Technology process revives rich, natural harmonics into the sterile, detached digital sound, adding an organic quality unlike any other.
K2 Technology processing revitalises the studio recording sound, infusing it with life once again.

K2HD Processing revives rich, natural harmonics into emotionally flat and lifeless digital recordings.
The unparalleled originality of K2HD lies in its advanced high-frequency extension, enabling the restoration of natural harmonics and overtones beyond 22kHz, delivering audio quality that is close to the original master.
The XMOS 16-Core chip processes the audio data received via the USB digital input.
This new low-latency XMOS microcontroller has greatly enhanced processing power. Compared to the current generation of eight-core chips, this new 16-core IC delivers double 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 perfect partnership with the 32-bit Cirrus Logic DAC chipset used in the GO bar.
