Entirely logical, but my point is that when it comes to audio and especially car audio, Harmann have expertise and manufacturing depth that frankly outclasses Sony. I think that for a given price point, Harmann can design and produce a better system. But we'll see soon enough.
I wonder how much leeway B&O has to improve the sound system?
Is the head unit Sony/B&O or is it Ford's Sync3?
I also assume Ford is not going to spend the money changing body and trim panels to suit B&O's preferences, so most likely B&O are restricted to the same number, size, and location of speakers as the Sony system.
And Ford's auto start/stop limits the stereo's power draw when the engine is off so they cannot use power as a differentiator either.
This is pure speculation on my part, but this upgrade could be as simple as a speaker swap between Sony and B&O. Maybe they make better speakers, but at the same price-point I assume it will be hard to tell the difference.
