The aluminum alloy chassis on the OG GO Bar has been swapped for a Japanese Stainless Steel chassis that promotes maximum rigidity.

It also features an ultra-low jitter internal clock and an enhanced power supply. Audiophiles will be delighted with the power and features of the iFi GO Bar Kensei, making it the ultimate hifi portable headphone companion for your high-end headphones and IEMs.

Kensei: An honorary title bestowed upon a Japanese warrior skilled in swordsmanship, a Kensei represents the highest degree of perfection. iFi Audio leaned into this with the design and craftsmanship of the GO Bar Kensei, focusing on purity, balance, and refinement to deliver a listening experience that they say ‘cuts through the noise of everyday life and reveals the true essence of your music.”

Product Details

K2HD Technology: The iFi GO Bar Kensei DAC/Amp is equipped with K2HD Technology, the latest and highest-resolution version of K2 technology. K2 technology restores music data lost during digitalization, bringing your audio closer to the analog master recording quality. It reproduces your music with richness and natural harmonics, adding an organic quality to the sound.

K2HD technology upscales a file to 192kHz/24-bit and applies hand-selected K2 parameters for waveform correction — Which processes the time-domain, not the frequency domain. Through advanced high-frequency range extension and minute signal (Bit) extension, K2HD technology restores natural harmonics and overtones beyond 22kHz, delivering listeners a sound quality that is close to the original master.

XSpace & XBass+: Designed for high-quality headphones, XSpace delivers a spacious sound field as if one was listening to speakers. XBass+ is designed to add back the loss bass response for a more accurate bass reproduction of the original music.

Four Digital Filters: Four digital filters tailor sonic characteristics according to the song. LED shows which filter is selected

  • Bit-Perfect (Blue): No digital filtering for natural tones. Delivers crisp, robust sound, sharp natural tones, and a fuller midrange.
  • GTO (White): Recovers inner resolution and music body. Enhances sound details and density.
  • Minimum Phase (Yellow): More life-like sound, between BP and STD. Offers slow-roll off with minimal pre and post ringing, slight reverberation and a warmer sound.
  • Standard (Red): Taut dynamics with controlled highs.

Two optimized output stages: Turbo Mode (6dB gain boost for power-hungry planar headphones), iEMatch for sensitive IEMs (cuts back background noise and hiss)

Two Balanced Outputs: 4.4mm balanced output with symmetrical twin-channel output stage, 3.5mm balanced output with iFi S-Balanced technology that cuts crosstalk by 50% for the best connectivity
