Know before you buy
K2 HD Technology is a digital processing method that restores the harmonic detail and richness often lost during the digital recording process. It essentially upscales your audio to provide a more natural, authentic sound that feels closer to the original master recording.
With a power output of up to 475mW at 32 Ohms, the GO bar Kensei is highly capable of driving a wide range of headphones, including many demanding over-ear models. It is significantly more powerful than the standard headphone jacks found on most laptops or smartphones.
iEMatch is designed to reduce background hiss and optimize volume control for sensitive in-ear monitors, while Turbo mode increases the gain to provide extra power for harder-to-drive, full-sized headphones. These settings allow you to tailor the output to match the specific requirements of your gear.
Yes, the device features full MQA decoding, allowing you to play back high-resolution MQA files from streaming services like Tidal without needing additional software processing. It handles the complete 'unfolding' of the file to ensure you hear the full quality of the recording.
Yes, the GO bar Kensei uses a standard USB-C input, making it compatible with most modern smartphones, tablets, and computers. You may need a specific adapter depending on your device's port, but it is designed to be a plug-and-play solution for mobile and desktop setups.
The four digital filters allow you to subtly adjust the sonic character of the DAC to suit your personal preference. While the differences are nuanced, they primarily alter the transient response and frequency roll-off, letting you choose between a sharper, more analytical sound or a smoother, more relaxed presentation.
