Sonore - Audirvana Plus 3.1 Output Mode

[vortecjr]

This thread is intended to be a supplement to the Sonore Rendu series user manuals. The manuals contain quick start information that can be viewed here:

Sonicorbiter Rendu Series - User Manuals

 

 

In order to enable the Audirvana Plus 3.1 output mode please following these steps:

1. Sonicorbiter v2.5 is required for the Audirvana Plus 3.1 output mode. Sonicorbiter v2.5 is available for older microRendu and comes standard on new microRendu and on all ultraRendu and Signature Rendu SE. Sonicorbiter v2.5 is not available for the Sonicorbiter SE. If you need the purchase Sonicorbiter v2.5 you can do so here: https://www.smallgreencomputer.com/pages/sonicorbiter-2-5

2. Go to www.sonicorbiter.com and select to Manage your unit.

3. Once you are running Sonicorbiter v2.5 go to Apps / Software Manager and press update.

4. Go to Settings / MPD/DLNA and press Save.

5. Go to Apps / Audio App Switcher and confirm that you have a green Active status next to MPD/DLNA. 

 

 

6. From Audirvana Plus 3.1 go to Preferences and then select the Audio System tab.

 

7. Enjoy!

Jesus, usually the messages you get when you complete an update tell you to reboot.  Is this unnecessary for this update?

 

Now it would be great if Damien releases A+ 3.1 so we can actually try it!

 

I think your title meant to say Sneak Peek.

At least go into Settings / MPD/DLNA and press save. It's coming soon. Spelling fixed.

Jesus, on 7/23 Damien said 'I'll release the public beta end of next week'.  So we should see A+ 3.1 public beta any day now.  Is the required update to SonicOrbiter 2.5 available yet?

We may need to do a small update....I'll keep you posted.

[vortecjr]

FYI:  Damien released the public beta of Audirvana Plus 3.1:

This has convinced me to buy a UR and explore... love Audirvana and Qobuz via my humble MacBook Pro...

 

That is inspiring!

This works really well ... Audirvana streaming to microRendu is a great combination. Great work by Sonore & Audirvana for this long awaited feature... by me, at any rate.

Thanks...I'll pass the compliment to Damien as well.

All that is needed for MQA to pass bit perfect data to a DAC that supports it. So no digital signal processing is permitted for MQA. 

[vortecjr]

Blue light is on my Brooklyn DAC and it's playing 24/352.8k Here is my setup using Audirvana:

 

[vortecjr]

News flash:

 

Sonicorbiter 2.3 should now properly support Audirvana Plus streaming. Please update your unit via Apps / Software Manager. Wait for the "Back to main menu" link to appear then reboot your unit.  

[vortecjr]

FYI:

 

Audirvana Plus 3.1 was been officially released and Sonore Ethernet to USB products (Sonicorbiter SE, microRendu, ultraRendu, and Signature Rendu SE) along with select Pioneer & Onkyo Group products are among the first to receive the "Works With Audirvana +" approval.  

[vortecjr]

Damien, has a Signature Rendu (SPDIF/I2S) unit in for testing. He is going to look into supporting it. These units are very different compared to current line of Ethernet to USB endpoints so figures crossed. Not ETA as of yet. 

[vortecjr]

I just clarified above in my earlier post what products are supported:

 

Sonore Ethernet to USB products (Sonicorbiter SE, microRendu, ultraRendu, and Signature Rendu SE) are among the first to receive the "Works With Audirvana +" approval.

[vortecjr]

If you went down that 'novel" way I'm afraid I can't help you because I don't keep track of that connection scheme. Maybe the guys promoting it can assist you. The unit is meant to be connected to a router or switch that connects back to the router. If your using a WiFi bridge the signal strength will matter a lot.

We updated Sonicorbiter 2.3 to provide full support for A+ streaming.  

[vortecjr]

Please keep this thread on topic and about the A+ and not about power supply tweaks.

What are the A+ settings - or anything else in the chain - to pay attention to in order to alleviate my skipping/stuttering issues? Just now playing an sacd iso ... on-going intermittent troubles!

3.1.5

There is nothing in the Rendu that you can play with. Some of the things to look into is the computer, any switches especially if they are managed.

Hi JR @vortecjr

 

When using A+ with the ultraRendu and DSD256 upsampling, do we need to reduce the memory buffer in A+ settings?

 

How much memory is in the ultraRendu?

 

And in the case of Audirvana + DSD256 upsampling + ultraRendu, is it the Mac that is doing the upsampling or the ultraRendu? Does the ultraRendu have the power?

 

Cheers in advance

 

As discussed above the Rendu is not resampling in this caes and more than capable of playing DSD256.

Same experience I'm having Jim.

 

So I guess this means the ultraRendu endpoint is doing the up-sampling, when using A+

If so, it makes sense that it would struggle with DSD128 up-sampling and higher, since the ultraRendu is a low powered endpoint (by design)

 

@vortecjr can correct me if I'm wrong

This is not correct. In fact, the Rendu is capable of some resampling, but in this case the unit is just a receiver.

Can the Rendu even fully buffer even a worst case DSD512 file, as well as the next track, as A+ does?

 

Do I need to change any of the buffer settings in A+ ? I've tried to ask Damien but no response yet.

 

How much RAM is in the ultraRendu?

 

 

Sorry...I don't generally discuss these things. Damien has a unit so wait for him to chime in. In the mean time you can describe your network....wifi, switches, router, etc.

Very simple network. No WiFi.

 

Gigabit modem/router > Netgear gigabit GS108 switch > ultraRendu

 

As mentioned the same chain has no issues with Roon doing the same thing - upsampling to DSD256 7th order.

 

But with A+ it even struggles with DSD128. So I wonder if it's a RAM thing, which is why I asked about the Rendu's RAM.

 

Roon doesn't buffer a track in memory like A+ does.

 

I not appropriate to compare Roon to A+ because these are two different protocols and resampling schemes. Have you tried bypassing the Netgear switch....just something to try. The Rendu's RAM is not an issue here.

A+ has the 512 indicated - you then need a dac that can do 1024. DOP rule for mac?

Only if your DAC does not support native DSD on the micro/ultra.

Jesus, I am still trying to understand this, and it might be helpful for everyone to read a full explanation here.  I think you are suggesting that for DSD 512, via Audirvana+, that the following can work:

 

1.  A+ oversamples to DSD 512

 

2. A+ packs the DSD 512 in a DoP 1411.2 kHz PCM "container"

 

3. The stream is sent out of the Mac to the Rendu as 1411.2 PCM (DoP)

 

4. The Rendu is capable of receiving the 1411.2 PCM stream and unpacking it to DSD 512

 

5. The Rendu then sends native DSD 512 to the DAC via USB

 

Is the above accurate as to how DSD 512 could work with A+ and the Rendu with a native DSD 512 capable DAC?

 

If not I do not understand how it could work, as my understanding is that a Mac cannot handle any native DSD (only DoP which to the OS is of course PCM).

I had a procedure yesterday and my doctor told me not to make any important decisions...so here goes:)

1. This should work with PCM to DSD conversion.

2. I don't think A+ can stream DSD as DoP and I'm not sure any DAC would support that rate via DoP.

3. Theoretically possible, but not a feature.

4. Theoretically possible, but not a feature.

5. This is supported on some DACs.

 

I think your confusion local playback with streaming.

So Jesus, you are suggesting that when streaming over Ethernet, Mac computers can output native DSD.  And you are saying that is what is happening when streaming DSD from A+, and that, if necessary, the Rendu will convert to DoP for DACs which require it?

Currently I oversample everything to DSD 128 via A+, and stream over Ethernet to the Signature Rendu SE.  I was under the impression that I was sending out DoP from the Mac, to the Rendu, but if what you seem to be suggesting is true, the Mac is actually outputting native DSD, and the Rendu is packing it as DoP.  I know my DAC is seeing DoP as it is not capable of decoding a native DSD USB data stream.

 

I also have not seen any DACs which claim to be capable of 1411.2 PCM (which of course would be necessary for DoP of DSD 512).  But I have had no problem sending DSD 256 via DoP to a DAC which can accept 705.6 PCM.

 

My confusion lies in my (apparently incorrect) assumption that Mac computers cannot output native DSD streams, as they are not compatible with .dsf, .dff, files through core audio, but perhaps A+ does enough to bypass core audio when outputting over Ethernet.

You have native DSD unchecked in Settings / MPD-DLNA because your DAC's USB input does not support native DSD streaming via Linux. I have native DSD checked in Settings / MPD-DLNA because my DAC supports native DSD. Below is the output of Apps / DAC diagnostics showing 88.2 as the output which is correct for native DSD64 streaming.

My understanding, fwiw, is that mac can only do DOP - hence, if I want dsd512,  I need a dac that is capable of ~x2 the pcm rate of my current iDSD micro which does 768 pcm & does dsd256 (only with roon! or mac direct to dac!). The iDSD micro will do dsd512 with windows & native dsd.

DoP only via local playback, but it has no issues sending native DSD to a micro/ultraRendu. Below is the output of Apps / DAC diagnostics showing 705.6 as the output which is correct for native DSD512 streaming.

@vortecjr:

 

705.6 PCM carries DSD 256

 

1411.2 PCM is required for DSD 512

Not with "native" DSD streaming. Those are DoP streaming rates.
