I've had all 3 over time in my cars. I'd rate them in the order:

Premium -> B&O -> Std

I think the lack of tweaking options on the B&O is possibly what damages it the most. The premium system is the best by quite a way. The B&O tweeters do add to the 'cool' of being in the AM.

 

Not when you are in a convertible. Placement of the tweeters in the calm dead space near the windshield provides far clearer sound when the top is down as compared to the Premium system. The B&O is the only system that I have heard that is satisfactory with the top down at speed.

 

I loaded up some CD's to really hear what the B&O can do. I am more impressed with than previously was. Natural sounding to me with some good detail. My Jag does a better job at surround sound and making less than ideal sources sound better. The B&O flaunts the flaws more which in car may not be the best thing.

 

 

Would rate the Meridian system in my previous DD (XFR-S) as equal or slightly superior to the B&O in my V12VS.

AM Premium system I had in my previous V12V and V8V is the best OEM system I have ever heard.
