The quest for the best DAC dongle under 100€ goes on. Will return the Ugreen Hifi Audio Pro and order an iBasso DC05.
While the Ugreen sounds great (and is basically a clone of the Meizu DAC), there's a lot of audible noise when using 4G networks. And this costs 40€, while my Apple dongle costs 9€ and has no such issue.
Just another single-user instance.
