got my hands on this recently, no issues with it whatsoever and brought life back to my Hugo TT -> Aune S17 Pro set-up after I felt like it lost some personality switching from USB to optical input. very pleased with the investment so far
I will say though the adapter they provide in the box (at least for UK units) utterly sucks as it doesn't seem to actually keep the plug in place, which didn't fill me with much optimism in its safety. luckily I had a travel adapter laying around so I've been using that instead, no problems
