I think the volume thing is not a hill of beans, just a muscle memory thing where the eyes tell you one thing but the ears say more. Once you get used to to 50-ish, it becomes second nature.
It’s nice to have consistency across B&O devices. B&O seems to think the volume level is the same, but it clearly is not. There are still a lot of bugs to work out in the Theatre. After investing as an early adopter in the most expensive soundbar on the market, I do want B&O to listen and improve.
