This is a review and measurements of the CIXUN USB-C to XLR adapter (balanced DAC)(1 meter). It was kindly donated by a member and cost just US $16 on Amazon including shipping!
The cabling and connectors are surprisingly good quality! I don't know that I can buy just the wires for this cost.
While there are a ton of USB-C DAC dongles, they lack balanced XLR output. So if this adapter (and others like it) perform, it would be a super useful way to drive balanced speakers without another box on our desk.
CIXUN USB-C to XLR Adapter Measurements
We start with our usual dashboard:
Gosh, this is not what I wanted to see. Instead of nominal 4 volt output, we only have 0.75 volt.
Not only that, there is a lot of low frequency noise including mains leakage which one hopes to avoid with balanced output. And series of distortion, pushing SINAD down to "poor" category.
Naturally, dynamic range is quite low, not remotely clearing 16 bit hurdle:
I suspect lots of jitter from the dashboard and that is indeed what we have:
Wideband THD+N sweep shows rising distortion at low frequencies:
The bit of good news is that frequency response is correct:
I don't think we need to run more tests.
Conclusions
What a useful and well built device we have here, sold at ridiculously low price. Alas, objective performance is quite poor across the board. There is an opportunity for a company with better know-how and care for measurements to build a better one and sell it at say, $49.
I can't recommend the CIXUN USB-C to XLR adapter. While it solves an important problem, it does so with almost no attention to design hygiene.

As always, questions, comments, recommendations, etc. are welcome.
