Know before you buy
K2HD technology is designed to restore the natural harmonics and nuances often lost during digital compression. It processes audio to sound closer to the original master recording, providing a more organic and detailed listening experience.
The GO bar Kensei is versatile enough for both. With a balanced output power of up to 7.2V at 600Ω, it has enough headroom to drive demanding high-impedance headphones, while the iEMatch feature ensures low-sensitivity IEMs remain quiet and hiss-free.
No, it is powered directly through the USB-C connection from your source device, such as a smartphone, tablet, or laptop. This makes it a true plug-and-play portable solution.
XBass+ adds a clean, deep boost to the low end without muddying the midrange, while XSpace widens the soundstage to create a more immersive, speaker-like presentation. Both are analog-domain signal processing features that can be toggled on or off based on your preference.
The unit features two outputs: a 4.4mm balanced jack for high-performance connections and a 3.5mm S-Balanced jack for standard headphones. The S-Balanced output is designed to reduce crosstalk and distortion even when using conventional single-ended cables.
Yes, it supports a wide range of formats including PCM up to 32-bit/384kHz, native DSD up to DSD256, 2x DXD, and full MQA decoding, ensuring compatibility with virtually all high-resolution streaming services and local files.
