In case it’s of help to others, I can also confirm this adapter works well, so far at least.
In an area with poor signal (signal level 41/100), I’ve gone from a flakey connection (Archer T2u Nano) at standard 44/16 to seemingly being able to stream DSD256 solidly (if I wanted). It’s very large and hideously ugly but can potentially be tucked away out of sight. Sure a cable would be a better bet but for now I’m hopeful this might do the trick.
