BluOS server with USB out?

I'm using a Node2i as my streamer and just got a new DAC.
The MP D2
https://www.musicalparadise.ca/store/index.php?route=product/product&path=61&product_id=97

I'm connected between the 2 with coaxial and there is an audible clicking when shuffling through songs via Qobuz and Spotify.
The designer said USB sounds better with his DAC and that the clicking is only audible via coax.
Therefore I'm looking for a BluOS server that has USB out and can bypass the DAC.
Does it exist?

Reply to my query last night about the issue from the Garry of MP
" If you use coaxial input, your specific player cuts off signals and on very fast when selecting different tracks, the DAC follows it to switch muting relay on/off. I will try to take a look at the firmware source code to find a solution to this compatibility issue. You can use a computer, cell phone or tablet to run  Qobuz and Spotify via USB. USB sounds better than coaxial and don't have this kind of issue."

I agree that it's problem with the MP and not the Node. I just assumed a few other DACs did this as well. As I seem to remember reading about this somewhere else. I could be wrong though. 

I don't understand why this would be acceptable to send out to the consumer with out a heads up.
Audiophiles seem to be OK with weird clicks for some reason. Plenty of relays seem to do this.

The 2 Schiit Pre's I had both made a horrible racket with every adjustment of the volume knob. They also both got rave reviews and I never read a word about the clicking relays in all of the reviews I read Until I got them home and went looking for what the issue was.
Apparently they were designed that way!!??

I have a Schiit SAGA pre in my bedroom system and it does indeed do this, but I think the clicking in these (2) scenarios are different.  Schiit admits that this is by design.  Doesn't bother me, but I know it was quite a pain for a few people.

IMHO, again, I really think the MP is defective.  I agree that this shouldn't happen with any DAC.  MP needs to check this and find a solution.

Good luck with your pursuit.

The DSpeaker X4 has a DAC I would send the other back. I never had a DAC that couldn't do coax correctly that's been around for 40 years.

That clicking is a technical problem with DACs that has to be addressed with a technical solution by the DAC mfg. This is a problem when switching between sampling frequencies (different tracks have different sample rates) and even worse when switching back and forth to/from DSD.
It is the DAC causing this, not the Bluesound unit. MP needs to get their tech(s) to solve it - likely by adding one or more relays (that seems to be how other mfg's solve this issue). Also should be quiet relays - if they are listening.
