For those of you that are Denafrips users, I wanted to feedback that I successfully updated my Ares II DAC with the latest DENAFRIPS 12th Anniv. Firmware.

CAJames mentioned that the process looked "straight forward," but I encountered several curves along the way.  I think some of that is language, and for me, an upgrade procedure like this always creates some anxiety.  

Alvin of Denefrips was very responsive to questions and offered guidance when I went in the wrong direction.  Bottom line: I got it.

I understand that upgrades to the Pontus II will be provided soon.

Update now available for the Pontus:

If your DAC is too old to be flashed, or you'd rather not mess with flashing, it looks like you can buy a new DSP module, with the updated FPGA, but you still need to open up the DAC to install it. It costs 300 bucks.

I have a Pontus II that I haven't completed the firmware update. However, I recently successfully upgraded the firmware on my Hermes DDC without issue, and, I'm far from being technically savvy. If the DAC firmware update is similar to the DDC, it should be a simple process.

I see a lot of people online saying they don't like the new firmware, specifically for the Pontus. That it makes the sound "too analytical" and "lacking warmth and bass." Many of them rolled back to the original firmware. I've wondered if this is more a reflection of their up/down stream system than the DAC itself and it's good to know you appreciate the new firmware.

I've still got a few weeks to wait. I'm not looking forward to moving my Terminator (it is heavy!) to take a picture of the chip. But while I'm at it I'll do the same for the Gaia as there is a rumored firmware update for it in the works as well.

I've learned from experience with my PS Audio DACs that firmware can take time to "settle in." Ted Smith, the designer of the amp and the firmwares suggests that is because most times a different, previously unused portion of the FPGA is put into play and that takes time to stablilize. One firmware in particular I spent weeks to get to sound right, and moved speakers around and rolled tubes. . . and it ended up after about three weeks sounding better than ever before. My advice to some who may want to roll back to a previous firmware: hang on.

Thanks Tony. I feel like if anything my system would benefit from a little less warmth and a more detailed/analytical sound so I'm not worried, esp. since they also make the old firmware available if you decide you don't like the new one. I will of course post my impressions on or about May 15 when the T2 firmware comes out.

I completed the firmware update on my Pontus II last Sunday.  I didn't notice immediate deterioration in SQ. Still early in the process though.  So probably best to allow proper burn-in time before making a final determination. At least there is the option to roll back the firmware!

Hey Tony,

Firmware for the original Terminator came out the other day, T2 is scheduled for May 15. I did open up my DAC to get a picture of the chip, so I'll be ready to go when it comes out.

I did the firmware upgrade on the Denafrips Ares 2 and it was a nice extension of the treble, better defined bass and soundstage. All in all, a nice change.

I also did the "tuning" described on YouTube from the German fellow, can't remember his name. It also created a nice improvement in definition and soundstage. Music felt less congested.

I added Hudson Hifi - large silicon feet - much more focus and musicality.

Finally, I forgot that I had a Zbox in another, rarely used system. I put this in after the DAC, before the CSP3, and now I get to tune the digital side with a tube. I was looking for a zbit, but for now, the Zbox(which is what Steve had in the output stage of his upgraded CD players) is working wonders. I'm using a GE 5751 at the moment. Cheers.

Yes, Tony that is it. I basically just loosened the screws and connectors a bit and used a washer on the back screw as he suggested. I had to take the lid off anyway to photograph the chip for the firmware upgrade.

You wouldn't expect loosening the connectors so they are not in death grip mode would made a difference. But, as I've learned in this hobby, small things often make a difference.

Finally got the new firmware for my T2. It installed without a hitch, I expected to reset the clock sync to my Gaia and the I2S pinout and I wasn't disappointed. First listen is positive, more transparent and maybe a little more treble energy. I'm going to let it burn in for a while, but I don't anticipate rolling back.
