What about something like this?

Cheers for the link, but trying to avoid extra boxes.

This is from the manual, guys, how are your settings especially the pcm filter and NOS mode?
what source do you use for dsd?

Do you play dsd512 from a computer and with which player? If you are on window 10.You can try with this free DSD sample https://drive.google.com/file/d/10fZrfaN81jQYBIMU96ialjNjnHcjJlAo/view?usp=sharing
Foobar2000 from Windows 10, if you have problems playing DSD let me know @ PMDo you play dsd512 from a computer and with which player? If you are on window 10.

I don´t know why Google doesn´t find it....or showImpressive. My worry about Gustard is product support. Last time I checked, they didn’t have a website and were only sold through eBay. I guess they are sold some other places now but I’d still like to know a little more about the company.
I'm sure volume adjustment is fine too. It's a 32-bit DAC so it can lose at least 8 bits and still have 24. Even better if the volume control uses more bits.I always use it for the NOS mode but never adjust volume from DAC
This is a bit concerning. Does it mean the X16 is sensitive to USB? Perhaps we need USB purifiers, audiophile cables and $5000 streamers after all...
In hours of testing, my signal chain stuttered twice, each for about 1 second. I have not started to trace down the issue. It could be Wi-Fi as my home is flooded with em waves, though this has not happened before.
Im just testing this more thouroughly and it also happens with my old mouse. Although less often. But yes, at least for me USB seems to be super sensitive. Display is also changing between MQA and PCM when it stutters. (could be a problem with Tidal or MQA too. but at the moment it doesnt work right.)
I am going to try the USB 2.0 ports on my RPi 4.With my current old dodgy PC (i5 2400, can't remember the motherboard), I will only get stutter free audio with the 'native' usb ports (the ones closer to the corner, the ones higher up if your PC is upright). I believe the additional ones in the middle uses a different 3rd party chipset, so perhaps has a higher latency or something. I see this with all my usb audio devices (Topping D10, Xonar U7, Creative SXFi). When I use the 3rd party chipset ports, I'll see stuttering that goes on and off, more likely to occur when there are higher levels of system processes working.
I just remembered how I fixed the stuttering, I don't let the PC go to sleep and that solved it for me.I am going to try the USB 2.0 ports on my RPi 4.
It's hard to reproduce, let along isolate, the stuttering issue. Around the same time, I got the X16 and upgraded Roon to 1.8. Wi-Fi issues are also hard to control.
If I hear more stuttering I will swap it with my other DAC and do more testing.

I use Ropieee 1.7. Updating to 1.8 will end up in a loop. I will try disabling wifi first per suggestions on the Room community.What firmware are you using on the RPi 4? I use the RPi 4 with Ropieee/RopieeeXL and haven't had any stuttering issues. If you are using Ropieee, check in the Advanced Tab that USB auto suspend is OFF.
Also there was a USB Firmware Version Update a few weeks ago, you can update on the on the Information Tab on the Ropieee web interface, in case that helps.
Very tempted to order one of these as a secondary Dac, but a little concerned about the fact audio gear ordered from China to the UK is often specced at 230V. The voltage around here at least (Hampshire, UK) is often around 247V, and I’m concerned about whether this high a voltage might be damaging to this Dac?
P.S. The measurements look incredible. Particularly that linearity! Would love to hear it in a properly setup dbt with the Mola Mola and Chord Dave. I’m sure there’d be little/no audible difference, but I’d still be intrigued... IF only I had access to all three!
