My system also contains an MA352. Listening room is upstairs and on the other end of the house. Dealer told me to consider a wall-wart extender instead of a wifi streamer. I think I ended up with the TP Link 1200 (sorry not home at the moment to verify).
I connected a decent Cat6 cable to this, which runs to an Innuos Mini mkiii ($1400) with external power supply ($800)The bits are then sent to a Wyred4Sound Dac-1, ($1300) then to a set of balanced inputs on the MA352. I’m not really a digital guy, but this set up is quite pleasing to my old ears. Many of the HQ files from Qobuz are equal to my vinyl set up.
