Dragon Cable Recommendation: we recommend pairing the Go Bar Kensei with the Black Dragon USB Cable. Our Black Dragon USB cable will bring an extraordinary amount of detail and resolution to the GO Bar Kensei. The Black Dragon USB cable is designed to transfer digital audio from your source device (like a computer, phone, tablet, or a digital audio player) to a USB-capable DAC like the Kensei. It is built to USB Audio specs.

Revitalise studio recording sound with legendary K2HD Technology: The iFi GO Bar Kensei 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.
