Okay, I'm now basically paralysed by indecision (first world problems) and can't decide whether to opt for the Audi Audio Upgrade or the B&O System. A few people seem to have flawless B&O systems, and some people have had significant issues. In fact, my first hand experience is that of a badly crackling B&O system on a test drive at the dealer. As you clearly can't beat the wisdom of strangers, I invite your opinions. My current thoughts are: Audi Audio Upgrade: + Should work as advertised out of the box + Saves me a few pounds + Should be sufficient for most of my Radio 4 listening and driving with passengers - Might lack a little punch for some music and when I'm driving alone - Lacks the wow factor of the speakers B&O System: + Clearly the best sound quality / volume available + Looks impressive too - Might have the dreaded crackle requiring multiple trips to the dealer to fix - Costs a little bit more As I'm leasing through the company the impact on cost is fairly negligible so it's really down to sound quality vs. potential crackle IMHO. So which one should it be?
