Thanks Rob, I listened to the Beats system in a Beats Polo yesterday and it was bassy and the vocals were distorted and muffled. No treble even with the treble on full. I also listened to the standard 2017 Seat Leon system and it was much better and clearer. I think I'll stick with the regular system as the Beats system might not be as clear and clean as I would like. Besides, I doubt if I'll be able to hear the Arona Beats system (I can't imagine any dealer stocking an Xcellence First Edition) so I would be mad to buy without hearing how it sounds first.
