A:AnswerI would not go over 32-40 without having an amplifier. At this range it's loud with great audio quality! From what I've seen you can use 60-80 but you're probably going to max out the volume.
A:AnswerThere seems to be some reason to believe that analog stick drift will reoccur with the PS5 DualSense controllers. In this teardown video the speaker mentions that the analog stick units used in the DualSense look to be the exact same units used in the Dualshock 4's. He starts talking about the analog stick units at around 3 min into the video: https://www.youtube.com/watch?v=4rNITneXnCo
But I gotta say I am in no way down on the DualSense -- it's the most amazing controller I've ever used and continue to be blown away by it.
Knowing there might be drift issues with the Dualsense has me searching for "playstation stick drift prevention", so a prevention method instead of a fix because as we know by now, there really isn't a permanent fix for the issue if you want to repair instead of replace.
One plus side about the DualSense design in terms of repairs is the components are very modular so replacement service might be less complicated than the Dualshock.
