Performance Sound vs High Performance Sound

Hello everyone, after I have found nothing suitable in the previous threads a new one. If there is already a corresponding topic, please link and close this here… > I ordered XC60 with “Standard” Audio “Performance Sound”. Didn’t know with my previous brands this strong diversification with three different audio qualities. Sure that one distinguishes between “Standard” and e.g. Bose / Dynaudio sound systems, but the high spread at Vol ov is already quite violent. The price difference of 610 EUR between performance and high performance (this is 1200 DM !!!) is also severe. That would be justified if the standard package is absolute scrap – and actually only serves to not have to deliver a black hole at the dashboard. Sure – with the XC60 no one could test the difference between the individual variants yet. But what does the Volvo XC70/S80/V70 fraction look like ? What is the difference here ? Are the 610 EUR difference justified ? Can one live in good conscience with the performance system ? Greeting, Tommy
