Don't want to derail the thread/conversation , but figured it might be of interest
to some to see the EQ with settings to take out the B&Q "adjustments" from factory.
The settings below are from my M5 which did come with the B&O system and had a few
upgrades done to it (front speakers, subwoofer, amplifier), the results have been a significant increase in sound stage and quality.
As it's an upgraded B&O system the settings below may NOT be working well for the standard B&O system
