Audio setting and sound quality??
Background: I am a long time owner of the facelifted W211 (2007), and recently acquired a facelifted W212 (2016). Both cars has upgraded Harmon Kardon audio system with Logic 7 sound. On both cars, I had Logic 7 turned on.
1. W211: the sound is not as clear, crystal and detail as the W212. However, to me, the sound on the W211 is FULLER, more ROUNDED, more RICH, and fell more surround. The bass is rich and powerful. I barely needed to adjust the bass (+2) and treble (+1)
2. W212: the sound is much more clear, detail. However, it sounds THIN, HOLLOW, and flat!. I tried many different adjustments, still the same!. Right now I have bass maxed out, treble +3 or +4, it still fell thin, flat. Even at mass bass, the bass feel weak (Im listening to mostly soft rock, pop musics)..
Im not sure if my system working properly (It should, scanning showed no error). Anything I can do to make it sound better?. How could the same systems, 10 years newer sound worser than the older system??
iPhone direct connection?
bluetooth audio?
CD or DVD-A?
