Sonore ultraRendu v1.3

[d_elm]

I hope in the product design process the use of a USPCB from microRendu or ultraRendu to a new device will be taken into consideration.  USB input on one end and outputs and power on the other would probably help as well.

@jaaptina Depends on how good your USB DAC input is ... in my case EITR made a significant difference with a Schiit Gungnir MB ... its Gen 2 USB input is not as good as S/PDIF, in my opinion. I have used both F1 (vBus powered and separate PS) & EITR with the microRendu and the EITR, in my setup, was the better of the two. The difference was not enormous but still worthwhile.

 

EDIT: Whether the ultraRendu improves over a microRendu when paired with a DDC like the EITR, I'm not sure. Perhaps marginal. 

 

To me ultraRendu improves over a microRendu when paired with Offramp 5 DDC.

Thanks for the input on EITR.

I wonder if Jesus or anyone else can comment as to whether the UltraRendu will work with an Amanero-based DAC such as the Lampizator?

Of course it will. However, I think what you are really asking is if native DSD works on it. I really can't say yes or no. All I can say is that it's up to Amanero or Lampizator to say that the Amanero's firmware works perfectly with the Linux native DSD driver.

Works smoothly for me and others. Just select native DSD and you're good to go (but it works in DOP as well).

Up to what DSD rate?  128, 256, or ?

With DoP no 256 since the max PCM rate is 384.

That's what I thought.  Same as with OSX.  

[unbalanced output]

Works perfectly with dsd256, let me know if I can help you with debugging. I don't have dsd512 so I can't confirm.

 

@vortecjr if I remember well, when I select DOP and dsd256 it does play fine with the Lampi. I might be mistaken though. Does the uR resample for compatibility? The Chord obviously doesn't work with the combination.

It would only work with native at 256 with Amenero. Chord does not support native DSD on Linux.

[unbalanced output]

Mojo only does DOP anyways. Let me double check the Amanero in DOP again, maybe I'm mistaken. 

[unbalanced output]

The Amanero definitely plays something with DSD256 through DOP, not quite good (some crackling noise and sounds lossy) but it does happen.

[jamesg11]

I get that crackling coming & going with dsf256.

My understanding was that it ought to be good if the dac can do pcm768, as with my iDSD micro dac. Certainly it works fine sometimes, then not others ... I’ve been trying to solve this by looking at cpu usage etc on my macmini which is locale of roon sw & music files. Still no success.

Amanero's issues are related to trying to make their device do something that it was not designed to do. The Native DSD drive was developed primarily for XMOS based devices which the Amanero is not. I have an iFi iDSD DAC here and it works fine. They have different firmwares and can try. If you are resampling or scanning a library these things can affect the stream.  

[jamesg11]

Thanks Jesus, that gives me another angle to approach this from - there are fw choices for the iDSD dac?

I’m not using the roon dsp at all, just native dsf256 files. /& the cpu & network usage on the macmini appears to be minimal.

There are a few firmware versions for each DAC. CPU usage is only one aspect of streaming. This issue can be some kind of interrupt on the network output. It can be the server performing process in the background like looking up metadata on the Internet. Do you have a managed switch in the loop? 

[jamesg11]

No switches here - ethernet cables, curious usb,  macmini, ultraRendu, idsd micro bl, lpsu.

Just pulled the trigger on the Ultrarendu.   I was going to update the MicroRendu to 1.4 Status and get the IsoRegen which would have put me out about about $550.   But after reading the posts here, where people don’t hear any significant difference with the IsoRegen and Ultrarendu and that the Ultrarendu is clearly better than the MicroRendu with IsoRegen, I decided to forgo that plan and just get the Ultrarendu.   It is a simpler setup.   I am anxious to hear the differences as I think the MicroRendu is pretty awesome sounding already.

Update on this issue. Updating the unit via Apps / Software Manager = problem solved.

Okay..keep us posted.

Yes, indeed! That did it ... max res files for the iDSD from a macmini, dsf256 & pcm768, now flowing along on Roon. Thank you.

 

But A+ is still a flakey mess. Fully untenable. Does that require a future sw tinker as well?

No. Roon just happen to have something they were working on at the server/renderer level.
