There is a huge difference between Dolby Atmos music and non-Atmos music. My system is Arc - Sub - 300s. For Atmos tracks I am usually at volume 29-30. With the same album in a different codec I have to use a volume of around 60 or more. God forbid I should mix Atmos & non-Atmos tracks in a playlist. TV volume and Atmos volume are closer to each other, but I don’t listen to TV that loud so maybe not a great comparison.
NOTE: My Volume Limit is set to 65.
