Frankly, a maximum volume limit won't stop an uncareful user. If it doesn't get loud enough, they'll look for something to disable so that they can get it louder.
I understand trying to limit it to prevent accidents, but if you teach someone to be careful about their hearing, and they consciously choose to disregard you, as long as the option's there there's a good chance they'll find it.
I still don't understand, what exactly is the problem with using Precut? And if you haven't established a problem with precut, why are we continuing this conversation at all, since it does everything you've asked so far?
