Do you use a managed router/switch? If so, try enabling “flow control” for the port the A6 is attached to. Solved my DSD multichannel issue.
Anyone noticed that the DMP-A6 as DAC connected to a Mac through USB supports (over DoP) till DSD256 and not DSD512?
If I remember correctly DoP will half the maximum DSD output.
It happened back in the day with my iFi Zen Dac V2 as well when it was connected to my MacBook Pro. It supports DSD 256 but with DoP it is DSD 128 max.

DoP requires higher pcm rate than the Eversolo can do to encapsulate DSD512. You need minimum 512 just to cover 256.

Aha! That could explain it. Seems like I’ll have to go the Linux or Windows route for the NAA 
Running NAA in a small Linux VM with USB pass-through on my Mac for this purpose especially. Works like a charm.

you do NAA with the eversolo?
Could you go into more detail?
What you highlighted gives the details. He’s suggesting using it as a DAC connected to NAA in a VM on Mac.

Could you (or @RBM) illustrate the full audio chain for my feeble brain?
I have used NAA to run HQPlayer on a mac, but the streamer was a Rasp Pi running RoPieeeXL, which supports/accommodates NAA). Then that gets sent to a DAC…
Just curious how you are setting this up with the eversolo, which doesn’t support NAA.
Again, brain feeble. Need more details to understand.
The Eversolo would be purely used as a UAB DAC connected to the mac which Runs NAA in a Linux VM container which passes through USB to the DAC.Its not limited by MacOS to DoP as NAA is running on Linux

@Simon_Arnold3 basically said it all – and more eloquently than I ever could. 
It’s less abstract in practice though: the VM is just a virtual computer running Linux on your Mac, comparable to a Pi running Roopieee. You can turn it on and off as you like or need. Once turned on, tor the DMP-A6 it is exactly as if it was connected via USB to a Linux computer directly – allowing for native DSD (and not being limited by DoP as on macOS).
By the way: Using an external NAA client together with the DMP-A6 means, that the eversolo can used only as a DAC and then you don’t see any metadatas on the display, which is for many owner very important.
ok, thank you, this is starting to make more sense. (Or at least it’s starting to make me care less about NAA functionality with the DMP-A6, as I’m using the Eversolo as a streamer transport, not a DAC.)
I just booted my creaking old Mac Mini 2014 off an HQP NAA image. $0 investment and works like a charm

Yeah, the VU meters should work though (I raised a bug)
Also Roon’s Web display might come in handy in this case, which I haven’t been get to work yet
I have just ordered one of these to act purely as a Streamer as I already have a DAC in my amp.
I am keeping my Nucleus to act as my Core and it also stores my music on the SSD.
The Eversolo will be connected to my Devialet 200 amp so I am assuming USB will be the best connection.
Its a good looking piece of kit so looking forward to receieving it.
What would be the best audio settings(upsampling/etc). in the DMP-A-6 when using roon ?
Can you have the display just showing the album cover only ?
For eg I am not interested in the file format and next track buttons on my screen as I will use the app to control it .
Some give USB a bad rap but I think it works just fine if the DAC supports it.
I go USB from the eversolo to an X-SPDIF2 DDC, then either I2S or AES/EBU to my Denafrips Pontus II DAC. i2s is more fiddly to set up, but not sure I hear any difference between i2s and AES/EBU.
Yeah, the Eversolo wouldn’t replace your core. No way to install roon server on it.
That’s the fun, figuring that out in your system.
I have it pass everything straight to the DAC, with no upsampling in the eversolo at all.
Sometimes I play with upsampling within roon to 192/24 or 176.4/24 but I don’t know that I really hear a difference over 44.1/16.
