 AK4495S Decoder features:

(AKM) Introduces the AK4495S with a higher precision 32-bit stereo DAC with 123 dB of dynamic range, stereo and 126 dB mono output with selectable 7-V analog power supply). It is the latest member (TM) family of Audio 4 Pro. Using a symmetric layout for the left and right channels of innovative design techniques to prevent signal quality deterioration, and a 32-bit digital operation module provides a complete 32-bit processing

The AK4495S integrates a newly developed circuit to achieve rich sound field and bass representations to achieve a music playback experience with less distortion. For sound quality considerations, the VDD, VREFH, VSS and VREFL pins are assigned for each L and R channel. In addition to these, each of the L and R channels has two tags to avoid the effects of common impedance and to achieve a low impedance performance as much as possible. 

 DAC core is use AKM's flagship AK4495 chip, AK4495 is better than the WM8741
