Receiver: XMOS XU208
DAC: ES9038Q2M
Async: Yes
Working with Volumio: Yes
Tested Versions and Platforms: Raspberry Pi4, Volumio v3.396
Hardware Mixer on Volumio: Yes
HW Mixer string: n/a
Comments: Immediately recognised by Volumio. Tested with .mp3, .flac (44.1 and 96 pcm) and .dsf (2.82 and 5.64 MHz / DSF 128).
Not tested with high res streaming.
Using the supplied USB cable there’s absolutely no noise. Recommended if you want a simple USB DAC only without pre-amp, etc.

Great sound for a very small price. Seems Topping’s getting better each round.

Just a remark on this DAC.
- They state MQA, but actual using it is a different balgame.
- With a vast majority of MQA tracks, this DAC fails. It can’t perform the full encoding and start switching MQA off/on/off/…
- They have decide that it’s nice to have the LCD screen on all time, which results in a LCD burn in.
- Support is not on par. Filed complaints more than a year ago. On the MQA part => nothing they can do. On LCD part => Silence. (Raised a support request again)
Carefull with that one connected to raspberry pi with volumio.
I’ve managed to burn one of the clocks three times by playing tracks of 44,1 or multiples followed by 48 or multiples (or vice-versa). The first times it occurs, it just makes some noise, and a power cycle resets it. But eventually it would stop working.
A pitty, as I loved the sound, specs and form factor.
Support from the retailer was good, they changed or repaired the unit every time, until I’ve decided that was enough and trade it for another model.
With the Pre Box S2 Digital, i use a SPDIF Cabel. I bought a Hifiberry Digi2 Pro.
Who updates the TOC? It appears a bit out of date compared to what’s been listed.
I know two of mine aren’t listed int he TOC.
Nobody, the community member who used to do this does not visit the forum very often anymore.

Updated the list. To be honest, this will happen occasionally as it’s a very time consuming thing to do.

Yes, I figured it’s time consuming. Easy enough to search
