Denafrips FPGA Firmware Update

Good point! Speaking for myself, I was not looking for any change in sound as I am happy with the sound of the DAC as is. What prompted me to try the update is the claim by Denafrips that they fixed issues such as "audio latency", "phase difference between L/R channels", "buffer overrun/underrun due to the Source's Clock and the DAC's Clock differences", etc. I couldn't care less about what they did with "Optimized DSP to improve the sonic performance"... 

If it ain't broke,  don't fix it.

JMHO

Agreed. To make it worse, now my Iris DDC is no longer working properly with I2S output to the T-Plus DAC running updated fw V3.7. I was told by Vinshine that my DDC itself needed a firmware fix since it is "old" (bought new in Oct 2021!). Still waiting for that promised DDC fw fix...

I was hearing micro-distortions (which has been reported by some as well, not all) with the v1.4 in my Pontus II. I probably did not give it enough time for burn-in for the sound. I could not live with micro-distortions. 

I have a Pontus ll that is 2years old now. Have not updated the firmware. I love it's sound.

What the heck are micro distortions???
