Compact Portable DAC and Amplifier
ES9281AC PRO DAC | RGB status indicator | Full support for a variety of devices
MQA rendering support | Supports 32bit/384kHz lossless audio | Supports DSD256
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.
High-end decoding
Immensely capable
With support up to 32bit/384kHz PCM and DSD256, you will surely be able to hear even the finest details within your music! *DoP mode supports up to DSD128, Native mode supports up to DSD256
Hey!
Also supports MQA
The KA1 has been officially certified by MQA to be truly capable of MQA rendering! *The KA1 includes MQA Renderer technology, which can connect to an MQA Core signal (from TIDAL streaming service, FiiO Music App or any other MQA enabled music services or media players) and complete the final unfold of an MQA file.
Charmingly colorful, RGB status indicator
The RGB status indicator not only features captivating looks, but also conveniently displays the current audio format and sampling rate.
