Denafrips FPGA Firmware Update

In case there are any Denafrips DAC owners out there that are not aware of the FPGA Firmware Update, here's the link:

I did the update on my Ares II earlier today and am currently enjoying the results.  It is definitely an improvement without question.


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???

FWIW I found the v3.7 on my TP to be better than v1.0.  I also have an Iris that while if functions properly playing over I2S, I need to reset the pin out to switch between PCM and DSD.

I also found the USB is now better than the I2S (wasn't so with v1.0) so I am keeping v3.7.  I have a Lampizator Golden Gate and use that as a reference to judge the change from v1.0 to v3.7.  

I suggest giving it a try, but let it burn in for a few hundred hours before listening.

Also I was using NOS, now I find OS with sharp filter cleaner and more pleasing especially with 16/44 files.


@anzaanimalclinic Thanks for sharing your experience. I had reservations about TP running V3.7 fw at the beginning due to added brightness to my system even after hundreds of hours of burn-in, although it did give more details, focus, and transparency to the sound. A week ago I changed XLR IC from pure silver to copper (Oyaide TUNAMI TERZO XX V2), left it on 24/7 with V3.7. I listened to the system again this morning, it sounded much better, the brightness has been tamed. Yes, I also like the OS mode now as it is more dynamic and 3-D,  the sound in NOS mode in comparison is somewhat muddied and flattened.  I prefer slow filter for my system. It just sounds more natural.  This was done with USB connection only, I didn't compare with Iris DDC I2S connection since I don't like having to switch I2S settings between FLAC and DSD playback. I'll give the DDC away to a friend ;)
