Sorry if this is an awfully naive question. I've been streaming Spotify Premium at it's highest res through a 3G EchoDot to my HiFi (Perreaux SM3 and PMF3150, Klipsch Chorus) for years. For a couple of reasons - the dodgy 3.5mm output and reading recent reviews of streamers - I'm considering a purchase of a WiiM Pro Plus. In the context I've described, am I going to realize a significant upgrade in sound quality? Thanks.
