Since here are some A9 volume experts, I would like to add my similar question here.
I have an A9 2nd generation. In the setup (web interface or app), I can set the standard default volume. I have to set this at level 50 which is very high (number).
I have also an A6 and a M5. On these two devices I set default volume to 25-35 and I have the feeling, that is almost the same as 50 on the A9. But the A9 is the most expensive and therefore I think it should be a lower number. Now I'm curious if the A9 is dead/faulty? On the BeoVision Avant 55 NG I have default volume at 32. My 20 years B&O experience tell me, that default at around 35 is ok on the devices.
What is you experience? Do you also have to set a higher number on the A9.
Of course, this is very individual - but compare with other B&O devices.
