I have the "HIFI Pro" option in my 550 and in my coming M5. I think this is the best original factory sound i have had in a BMW.
A HIFI magazine here in Sweden tested car HIFI a year ago, Audi A8 with B&O, BMW 7 with HIFI Pro and a MB S Class.
The best sound was the B&O but i cost 8 time more than the HIFI Pro system in the BMW, and some of the test persons liked the sound in the BMW better than the expensive B&O. So best sound for the money were the HIFI Pro in the BMW.
The MB was not in the same class as the other.
Im interested in home HIFI and i have never heard a B&O that sounds better than other Hi end products that always costs at least half the price of the B&O...
So no B&O in my car
