One machine infinite possibilities.

Discontinued chips, no wastage - dual AK4497, unleashes the full potential of the flagship DAC; Large surface area, endless possibilities - the industry's largest interchangeable module for analog PCBA area; Non-Android, very pure - a brand new LP OS with a more powerful MCU. 

The new DAP is made possible by utilizing the last batch of AK4497 DACs in the world

AK4497 is a voltage-type DAC, not the current-type DAC AK4499, and therefore does not require additional I/V conversion.It is more suitable for portable DAPs. When designed properly, we can fully optimize its potential.In terms of actual performance: a portable DAP using AK4497 exceeds AK4499 based DAP in all aspects. 

How powerful is the DAP that fully exploits the AK4497?
