FAQ — GO bar Kensei
What is K2-Technology and how does it benefit sound quality?
Developed by JVCKENWOOD, K2-Technology is an advanced signal processing algorithm that revives lost harmonic content, timing cues, and high-frequency nuances, restoring digital audio to match the organic warmth of the original master recording.
How does the GO bar Kensei differ from the original GO bar?
The iFi GO bar Kensei upgrades to a forged Japanese Stainless Steel chassis for enhanced EMI shielding, integrates JVCKENWOOD K2-Technology processing, features an upgraded power supply layout, and delivers higher overall driving power and audio refinement.
Does the GO bar Kensei require an internal battery?
No. The unit operates efficiently on USB bus power directly from your smartphone, tablet, or computer, utilizing enhanced power supply cleansing filters to prevent dirty bus power from affecting audio quality.
