Question for anyone who has listened to both the current 3's "Premium Audio" and the S's UHFS ("Ultra High Fidelity Sound"), how do they compare? The S has an interesting speaker layout where the whole front of the cabin gets speakers, you can see them in the front dash panel and in the base of the A-pillars. Does the 3 have a similar layout in the front of the cabin? How do they compare in terms of sound? Thanks!
