Problems with Ultrarendu and Burson 3X GT

Hi everyone, I hope someone can help as things are getting a bit frustrating here…

A couple of months ago I decided to upgrade my computer audio system. Ended up with my laptop running Roon Core, an Ultrarendu as a bridge on the same network, and a Chord Hugo (original) as my DAC / Headphone amp. Worked pretty well tbh but still had the bug to try new stuff.

So I ended up buying a Burson Conductor 3X GT, a unit that I think sounds awesome. I’ve also swapped out my aging laptop for a Mac Air M2 (which is just a massive improvement all around).

However, I’m now really struggling to get it all working together. The Burson works if fed directly from the Macbook (shows up on Roon. The Ultrarendu is visible on the network (sonicorbiter webpage), the UR ‘sees’ the Burson when I check thee DAC diagnostics, Ive re installed Roon, restarted Roon Ready on Sonicorbiter, rebooted and even powered down the UR, all to no effect
The UR works, if I plug the Hugo back in (in place of the Burson) then it’s all good.
The UR won’t show up on Roon if not plugged into either DAC or if plugged into the Burson.
Running 'Roon Ready Diagnostic" on Sonicorbiter results in an ‘Error 500 Service unavailable’ message on my browser. When plugged into the Burson. It works OK when plugged into the Chord…
I’ll try to attach some screenshots

How to attach screenshots??



Those first two are the details of what the Ultrarendu sees when attached to the Burson


Second two are with the Chord Hugo attached


Roon with GT attached directly to Macbook


Roon with UR and Hugo pair attached


Roon with UR and Burson pair attached


Result of ‘Roon ready diagnostics’ with Burson attached to UR (Sonicorbiter software)


Same, with Hugo in the system

So theoretically all items are working, just that somewhere, somehow the connection between the UR and the Burson is not quite right???

I think you need to post these details on the Sonore support site here https://forums.sonicorbiter.com/

I have Burson 3X/GT and cannot get it to work with Roon either. I have emailed Burson but they never respond. Their dealer started blaming my opticalRendu that has worked on dozen of DACs.

I finally got it all to work together. It was to do with the UltraRendu ‘software’ settings. I can’t be more specific unfortunately as the internet is currently down (working off of my phone to write this) but I can say that it took me a long time to finally find the correct setting. Neither Burson or Sonore were particularly helpful although they did both answer my emails.
Again, sorry to be so unspecific but just keep digging in the online software and you should eventually come to a section that allows you to choose the 3XGT from a drop-down menu. It’s worth the effort and frustration, the 3XGT is a great sounding device

Simon_Amos, your comments dont seem right to me because we dont have a drop down where you select a USB device. Except, if you setup up a custom DAC which you don’t need to do with your device. The other thing is that this option for a custom DAC is not available on all SO operating systems. What version of SO does your unit have?

My Burson with not respond back with a setting to Roon. With www.sonciorbiter.com you go to the Apps selection DAC diagnostics and review the DAC respnices to Roon. My redue is running 2.8.
If you find a solution please pass it along.

Burson is horrible about responding.

I think it was this:

I’m fairly sure that was where I finally solved it, however these are some other screenshots of other parts



Running V 2.8

Do not use custom DAC! If used, delete the entry and reboot.

Just to check before I do that; the entry for ‘Burson 3xGT’ in the drop-down menu for Roon Ready Settings / Audio device will be available without the custom DAC setting being configured as per the screenshot?

I’m pretty confident that it was when I found this that I got the setup to work, not sure if it was there previous to entering the custom settings. Im not saying it wasn’t but I hadn’t seen it beforehand
