How can I get the last FPGA update for my Denafrips Ares II?

Use the Vinshine website.  I believe he stated that he would do best he could to support folks who purchased Denafrips through him.

I tried to message him trough the forum. no answer, yet.

Did you try Alvin at Vinshne?  He might be able to help you.

I told him to contact tech support ,I don’t know anything about their programming 

if very old there may not be any further upgrade ,only  support@denafrips.com

Contact Audioman58.  He is the new US distributor 

I already contacted them and they told me there is no update beside the usb mcu 3.14. No fpga update from them. That's why I'm looking for an alternate solution.

Contact Denafrips directly and ask them.  There was someone on here recently that was looking for the Pontus updates and I believe he contacted Denafrips and got them.
