noticeable in what direction? Car direct is better? If so maybe there’s just something funky going on in my car but I felt mine was pretty poor even with quality setting at highest.
I have changed the quality settings on the trucks. It’s absolutely the case, Bluetooth sounds noticeably better. Bluetooth has plenty high a transmission rate for quality car audio imho and is plenty sufficient for Spotifys highest quality settings. It’s not the same as a direct connection but Spotify compression negates the direct advantage, and their built in stream just sounds worse to me even on max settings
