Forged for Masters of Audio

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.

Revitalize Studio Recording Sound with Legendary K2HD

Despite their pristine clarity, digital recordings sometimes seem emotionally flat and lifeless. Engineers at Victor Studio noticed a lack of emotion between their original masters and digital sub-masters, sparking a quest for a solution. They meticulously compared countless finished recordings with the copy recordings by ear, relying on their instinctive feel and human expertise. Their solution: K2 Technology.  The K2 Technology process revives rich, natural harmonics into digital sound, adding an organic quality unlike any other. K2 Technology processing revitalizes the studio recording sound, infusing it with life once again.

Tailored. Sweet Sound.

Listen the way you like with four bespoke digital filters and two analogue processing modes, each tailored to enhance your enjoyment across different music genres.

Bit-Perfect: Delivers natural tones, ideal for all genres.

GTO: Enhances sound details and density, particularly suited for Vocal tracks.

Minimum Phase: Produces a warmer sound, blending characteristics of Bit-Perfect and Standard, perfect for Soul and Jazz.

Standard: Offers a tighter sound with controlled highs, perfect for Pop music and Movie OST.

Advanced chip. Accurate clock.

The DAC section of the GO bar Kensei uses a powerful 16-core XMOS micro controller to process the audio data received at the USB input. Our in-house team has programmed the XMOS firmware to optimize sound quality and ensure a perfect partnership with the 32-bit Cirrus Logic DAC chipset. A customized digital filter minimizes pre-echoes and ringing artefacts. Our GMT (Global Master Timing) precision clock system ensures ultra-low jitter.

Supports higher-than-streaming audio formats:

  • PCM up to 32-bit/384kHz
  • Native DSD playback up to DSD256
  • 2x DXD
  • Full MQA decoding

Compact and Powerful.

The GO Bar Kensei is crafted with Japanese stainless steel for maximum rigidity. With its compact dimensions of 65 x 22 x 13.2 mm, it matches the size of a USB flash drive. This makes it the perfect travel companion for your mobile, tablet or MacBook Pro, blending into your life for headphone use. Its USB-C connectivity ensures plug-and-play convenience, allowing for hassle-free use. The GO Bar Kensei offers a maximum output power of up to 477mW, which is about 10 times more powerful than an iPhone 15*. It incorporates two power tuning technologies: iEMatch for high-sensitivity IEMs, and Turbo mode for power-hungry headphones. This allows it to easily drive a wide range of premium earphones and headphones.

Cut the Crosstalk.

Connect to the GO bar Kensei via 3.5mm S-Balanced or 4.4mm Balanced headphone outputs. iFi’s exclusive 3.5mm S-Balanced technology cuts crosstalk and noise by 50% with regular single-ended headphones.
