here is the Change log for the Ares II FPGA chip EP4CE22F
REVISION HISTORY
-----------------------------------------------------
v1.0 (Jan 01, 2020)
-----------------------------------------------------
* Original Firmware
-----------------------------------------------------
v1.6 (March 08, 2023)
-----------------------------------------------------
* Improved Adaptive FIFO Buffer & Reclocking Architecture
* Reduced the effect of Buffer overrun/underrun due to the Source's Clock and the DAC's Clock differences
* Eliminate Phase Difference between L/R Channels
* Optimised DSP to improve the sonic performance
-----------------------------------------------------
v1.8 (July 06, 2023)
-----------------------------------------------------
* Reduce sampling rate change/switching noise with certain transport/streamer
* Fine-tune the sound quality in the mid-range and lower octave of the bass, to achieve a balanced, organic, analog-like sound signature that is characteristic of Denafrips
