Luxury & Precision E7: High-end player unveiled

Luxury & Precision E7 is a new high-end player based on two AK4497 chips. It is stated that this is the last batch of these chips in the world. L&P E7 is available in two versions – Standard and Exclusive. The new product is notable for its modular design.

One machine with endless possibilities
Discontinued ICs, dual AK4497 unleash the full potential of a flagship DAC; Large surface area, limitless capabilities of the industry's largest plug-in analog PCBA module; Not Android – a completely new LP OS with a more powerful MCU.

The new DAP is made possible by using the world's latest batch of AK4497 DAC
The AK4497 is a voltage type DAC and not a current type DAC like the AK4499 and therefore does not require additional I/V conversion. It is more suitable for portable DACs. With the right design, we can optimize its full potential. In terms of actual performance, the DAC using the AK4497 outperforms the AK4499 based DAC in every aspect.
