Hi guys, as you may have read in some earlier posts, I'm getting ready in the next month or so, to pull the trigger on a S-Line Sportback. With the exception of the engines (see other thread), I'm pretty sure of my spec (as I like my toys and luxury), but the one thing I'm not decided about is the Â£500 ish difference betwwen the Audi Sound System option (Â£255.00) vs the B&O System (Â£750.00). Looking at the specs, the B&O system is obviously more powerful with 705watts vs 180 watts of the Audi system. But looking a little deeper, it "seems" that the B&O system's main difference (apart from power) is the 5.1 surround sound mode with the extra 4 speakers in the pillars for the surround effect ? As I don't really expect to be playing movies in the car but love my music, then for just music listening, is the B&O system worth the additional Â£500 or does the Audi system still do very well ? I appreciate that the B&O system probably uses higher quality main speakers in the doors. I notice the Audi system still uses a centre speaker and it looks like a similar sub in the space wheel well as the B&O, so has anyone actually listened to both systems and can draw any comiparisions ? Thanks.
