Compact stature Massive potential

What can be accomplished in a tiny space of 40x15x8mm? In the KA1, there is not only a high-quality DAC, but there is also premium audio amplification to match, both carefully tuned by engineers to truly and faithfully reproduce your music the way it was meant to be heard. The KA1 invites you to listen to it among other portable DAC and amps.

Made with a robust “heart”, for maximum effect

Employed in the KA1 is the ES9281AC PRO chip from ESS, which combines USB audio interface, DAC, and amplifier into one package. When combined with the multi-layered HDI gold-plated PCB it is on, the result is lower crosstalk, higher efficiency through lower power consumption, and ultimately high quality pure sound.
