K2HD Technology
At the heart of the iFi GO Bar Kensei lies the revolutionary K2HD Technology, a hallmark of audio perfection. Developed by JVCKENWOOD's sound engineers, K2HD Technology works to restore music to the same quality as the original master, reviving it with the rich, natural harmonics lost during digitalisation. This advanced processing, coupled with the GO Bar Kensei's dedication to perfection, ensures that every note resonates with depth and clarity.
Enhanced Circuitry & Connections
The GO Bar Kensei offers a tailored, personal experience for the listener thanks to four digital filter options as well as XBass+ and XSpace options to create a more accurate bass response and spacious sound field. An enhanced power and clock circuitry produces a wider soundstage, more detail and a more robust bass to appease the pickiest of audiophiles. Equipped with a 4.4mm balanced output, a symmetrical twin-mono output stage, and a formidable 477mW maximum output power, the GO Bar Kensei delivers audio performance that exceeds expectations. Additionally, iEMatch fine tunes the output levels for sensitive IEMs while Turbo Mode adds 6dB for hungrier headphones.
Design steeped in Japanese history
Crafted from Japanese Stainless Steel for maximum rigidity, the GO Bar Kensei draws upon inspiration from the craftsmanship of a Kensei's legendary blade. With meticulous attention to detail, each component of this ultraportable DAC embodies the essence of excellence, delivering music in its purest form.
