Hello guys.So im not like an audiophile expert or something but i want to get best possible quality from songs.I am currently using a sony str db940 and i hooked to it a pair of b&w dm601 and a b&w as6 for music.I want to know what i should buy(as cheap possible) to play lossless pure music without getting resampling and get the best results.I have a tv box connected through optical to the avr but i heard that android makes audio worse.I use spotify/tidal lossless to stream but they dont have the exclusive mode on android sadly.Anyone have any tips or uses a similar setup.I want to know what device and whay equalizer settings i should do on my avr.And if i should go optical or analog way.Thank you
