Stream to AV receiver over network

It’s an Android phone, I guess what I need is to be able to install wmp onto the nas? The app I have Is struggling to cope with bit for bit CD copies which i’m hoping will be fixed as it works with mp3 files, but all my music is exact audio copies(which are .wav files) which I can play from wmp on win 7 fine… So yes I think the receiver (Arcam avr 600) will handle it ok… (famous last words lol)
