DENAFRIPS DAC ---- Owner Impressions, Feedback, General Discussion, Questions and more....

Thread for OWNER IMPRESSIONS, FEEDBACK, QUESTIONS, ETC. regarding DENAFRIPS DACs.

DENAFRIPS lists the following R2R DACs:

Ares, Pontus, Venus, and Terminator (in increasing price order).

"DENAFRIPS incorporated in year 2012, focus in developing high end audio equipment at a very affordable price. Throughout the years of intense Research & Development, and continuous improvement of the product lines, DENAFRIPS had finally settled with the current product range equipped with R-2R ladder DAC technology. The reason behind this is the designer strongly believe that R-2R DAC is the best way to reproduce music.

The name, DENAFRIPS, stand for:

D-ynamic
E-xquisite
N-atural
A-ttractive
F-idelity
R-efined
I-ntoxicating
P-ure
S-ophisticated

This mean a lot and it is the house-sound of all DENAFRIPS products." [Copied From Denafrips About Us section]

IME when I was using upsampling, the Terminator board when changing upsampling content / parameters sometimes (and this was very very sporadic) with the latest firmware was playing with a background "ringing" noise, stopping and starting with different source content or powering cycle fixed it. Mainly with PCM which is what I was sending to the board. I expect the next firmware release to fix this.

Thanks Luis. Not sure I would describe the effect the same but possibly the same parameters. A very distinct and loud distortion and hiss. Definitely goes away if I change content or restart the play. I actually was not aware of the firmware updates. I’m guessing it’s going to have to be done with a Windows computer which I don’t have. All Mac and Apple here.  Will look into it. Thanks

Well the only time I experienced a loud distortion and hiss was with the 1st Amanero board, possibly with the end of 2018 firmware for the new board (1st iteration) which was very stable with the update from Nov 2019, that update was revealing. MCU and FPGA update. If your DAC is from Nov 2019 or newer it should have such firmware. Which by the way brings the SQ to an entire new level.

FWIW and IMO using Roon by itself I prefer the Terminator with PCM max native rate and not upsampling in Roon. Terminator in OS mode (not NOS)
If you use HQPe (which I prefer to Roon alone) then PCM max upsampling 1536 with 19 bits and Termy in NOS mode.
Again this is just my preferenceThis is a wonderful DAC, I would love to hear comments for the DAC and the DDC as well

Another member on AS provided these Roon settings and I gotta say, I'm really liking them on my Terminator (my ultraRendu is set to native DSD), I am streaming Tidal and local files:

Roon Instructions:

 

In Roon, tap the speaker icon in the bottom right corner, tap "DSP".  tap "Headroom Management", and set the value to -5 dB, this lowers the level before oversampling to avoid clipping during the oversampling process.  In the same field, set "Show Clipping Indicator" to "on".  This will tell you if you have an clipping during playback (if you do, you can lower the headroom management a couple more dB, but usually -5 dB is enough).  Tap, "Sample Rate Conversion", and set sample rate conversion to "DSD".  Set "DSD Sample Rate" to 256,  Set "Sample Rate Conversion Filter" to "Precise, Linear Phase" (I prefer this setting, but you can try others of course).  Set "Sigma Delta Modulator" to "7th order CLANS", leave "SDM Gain Adjustment" at "0", set "Parallelize Sigma-Delta Modulator" to "Yes", set "Enable Native DSD Processing" to "Yes".  The DSD to PCM settings are irrelevant.

Before you exit, double check on the left that "Headroom Management", and "Sample Rate Conversion" are enabled.


Just thought I would share with this group.


P.S.  Looking forward to my Gaia- should ship within the next week or two!
