Advice on choosing between two B9.5 S5 Sportbacks

I’m looking for advice and some loved experience from anyone who has a B9.5 S5. I’m going to see two of them at the weekend - the first is a grey Edition 1 (highly specced but doesn’t have the B&O sound system), the second is glacier white, slightly newer - so not Edition 1, but doesn’t have the B&O sound upgrade in the comfort and sound pack. I think the only thing the white one doesn’t have that the grey does is the laser headlight upgrade.

I guess my question is, is the B&O system worth walking away from the grey Edition 1 for? I do spend a lot of time in my car and listening to music. I generally take a lot of care when buying headphones or speakers for home and personal use so am I likely to notice the difference between the standard Audi system vs the B&O? I don’t think I’d go as far as to say I’m an audiophile but I do care about good quality sound equipment and enjoying music - I’d notice if it was awful.

Both cars are a similar price with the Edition 1 without the B&O system being slightly more expensive.
