(March 4, 2024) In an era when digital music has become the norm, iFi Audio says its latest creation, the GO Bar Kensei (buy it on Amazon), breaks new ground for the headphone-hungry audio fan. Mixing cutting-edge DAC technology with engineering precision and artistic craftsmanship, the GO Bar Kensei is billed to pack quite the portable punch.
Central to the GO Bar Kensei's technical appeal is its use of K2HD technology, an advanced audio processing technique developed by JVCKENWOOD. K2HD is dedicated to restoring digital music files to the full richness and clarity of original master recordings. By addressing the limitations of CD specifications that cut off all data above 22kHz, K2HD processing breathes life into music, restoring the natural harmonics and overtones lost in digitalization. It can also improve an audio file's resolution by optionally upscaling it to 192kHz/24-bit.
The heart of the Kensei's digital processing prowess lies in its DAC stage, which incorporates a Cirrus Logic DAC chip known for its natural-sounding musicality and exceptional signal-to-noise ratio. Complemented by a 32-bit, 16-core XMOS Cortex microcontroller, the GO Bar Kensei's digital engine is seriously robust.
The GO Bar Kensei also offers four digital filter options to fine-tune audio output. Whether you prefer the crispness of Bit-Perfect processing or the warmth of the Minimum Phase filter, the GO Bar Kensei adapts to your listening preferences on the fly. Adding another layer to this personalized experience are the XBass+ and XSpace analogue processing modes. XBass+ enhances low frequencies without altering the midrange, making it an interesting option for the bass-light nature of some open-back headphones. XSpace, on the other hand, is designed to expand a soundstage, offering a more immersive listening experience reminiscent of speaker-based audio.
Despite its compact size, the Kensei has some pep (up to 477mW of continuous power) capable of driving a wide range of headphones, from the most sensitive IEMs to power-hungry over-ear models. This versatility is made possible by its robust internal circuitry, which includes an optimized power supply and ultra-low jitter clock, ensuring that the Kensei delivers a clear, detailed sound across its output range.
In keeping with the spirit of Kensei warriors, the GO Bar Kensei's design pays homage to the artistry and precision of Japanese swordsmanship. Each unit is presented in a traditional wooden box with handmade engravings, underscoring iFi Audio's dedication to craftsmanship and quality.
With its revolutionary K2HD technology, customizable audio settings, and robust power output, the iFi GO Bar Kensei looks like a portable DAC gem on paper. Priced at $449, it can be purchased today.
