Description

The AK4499EQ current-output DAC is AKM’s latest VELVET SOUND VERITA product, following on from the previous flagship device, the AK4497EQ.

Current-output DAC Achieves Best-in-Class Performance

AKM’s Low-Distortion Technology has been optimized for the AK4499’s current-output architecture, resulting in a THD+N measurement of -124dB. The AK4499EQ achieves SNR of 140dB in mono mode.

Dynamic High-Resolution Playback with Incredible Detail

The AK4499EQ is produced using the same Premium Audio LSI process and Non-Magnetic Packaging technology originally developed for the AK4497EQ. These techniques dramatically improve noise performance, especially in the traditionally problematic lower frequency range.
