Help with Denafrips Ares DAC and microRendu

(Jesus Rodriguez) #7

Is this still not working with Roon? If so, can you post the information from DAC / Diagnostics.

#8

Thanks for chiming in.

It is working today afte Alvin (Denafrips rep) made some changes remotely to mRendu settings (see first screenshot).

Second screenshot shows the DAC diagnostics screen.

Let me know if you something unusual.

@thyname, I’ve intention to order this unit from my local dealer, Vineshine Audio and use it as a desktop DAC with my amp drving HD650 headphones. Do you have any issue when playing back on Roon itself using the download Windows driver? It is possible the DAC can do the followings:-

  1. Able to playback up to 24/384k?
  2. Able to playback up to DSD256 natively (not DOP)

Thank you for time.

It is going to be tough to accomplish this, as my PC where Roon Core is located, attached to the router is in a different floor of my house than my headphones equipment. Maybe I can try this during the weekend.

Also, I don’t have DSD files (yet). My music is all CDs ripped to ALAC, plus streaming Tidal Hifi. Maybe I buy some DSD during the weekend

To do the test @MusicEar is asking for, you could just use Roon’s DSP to upsample some Red Book material to DSD256.

The image is blurry. Can you post the information next to DAC description?

(Jesus Rodriguez) #13

The unit does not support native DSD with Linux right now. I’m going work on that for you, but it’s going to take a while though.

#14

Thanks for looking into this.

Next to DAC description is USB Audio 2.0 20b1:2005

Looking to the images I posted right now in a PC, and they look fine. Completely readable.

Can you elaborate a bit on your second post above … “unit does not support native DSD with Linux”…?

Also, would you be able to tell why I had those dropouts with “regular” mRendu settings before Alvin made those changes?

Finally, Alvin mentioned “increasing buffering size” on his communications to me, but not sure why. mRendu has worked great out-of-the-box with my other DACs I have / had in the same setup (Bifrost 4490, Mimby, Deckard, Matrix Quattro II).

Thanks!

I guess the setting i made should be fine. Would love to hear experts opinion if there is any other thing to further optimize :grinning:

#16

I tried this. See pictures. Music skips.

#17

More. I forgot I had a DSD 64 album. It does not look like Ares support DSD, unless I am doing something wrong.

(Jesus Rodriguez) #18

You have to select DoP in the mciroRendu.

#19

Native DSP was in response to @MusicEar request. I know you mentioned it does not support Native DSP in Linux, and you are working on it.

(Alvin Chee) #20

DoP DSD should work well with Ares.

#21

Yes indeed. DoD works well and Roon / mRendu preserves the DSD signal path.

Awesome ! :heart_eyes:

Got a loan set more than week back(XMOS chipset), it worked fine with ROCK and Auralic Aries but one major issue. In both cases, Ares output a loud hissing noise when boot up together with ROCK or Aries Mini. The loud hissing noise will go away once I started to playback track. Playing back DSD512 also resulted in loud hissing noise though Ares is not certified for DSD512.

I saw 48kHz, DSD and 8x LEDs lit up when boot up, so I assumed the problem happened here. After I started playing track, the LEDs lit up to respective sample rate, for instance DSD256; DSD and 4x will LEDs lit up and playing fine. Another finding, it only happened on ROCK and Aries Mini and not Roon running on Windows. I noticed when boot up the LED 44.1k is the only one that lit up. According to Alvin, the Amanero chipset will resolve the issue but I still waiting to test out. If it works flawlessly I will get one from him for my room headphone listening.

Add: the setup does not use MicroRendu, direct USB connection. By the way Native DSD works flawlessly when using ROCK or Aries Mini up to DSD256. For Windows only DoP is supported up to DSD256.

Hi @MusicEar,

New Ares come with Amanero USB interface, it should mitigate the said issue.

I’ve roon in Win10 NUC, tried it with Pontus (it has same Amanero USB interface of the new Ares), works well without the hiss. SOtM sMS-200ultra (roon endpoint), connects to the Pontus, works well too.

:slight_smile:

#25

That’s encouraging since sMS-200ultra runs a proprietary Linux. Amanero USB interface is not as wide spread used as compared to XMOS. I wondering is there any SQ difference?

(Alvin Chee) #26

DENAFRIPS believe Amanero USB interface remains the best available to date. :smiley:
