If my source is Spotify from a Samsung note phone, will there be any difference in sound quality in speakers between BT4 without aptx, and BT 5 with aptx?
The existing Spotify Premium maxes out at 320 kbps so I doubt you will notice any difference in SQ. But with the upcoming Spotify HiFi, yes, as they are supposed to give CD quality. You would, however, benefit from better range and latency.
