Default Best earpiece volume without distortion?

I've been playing with mixer paths and have set some values from 84 to 93 to 98 (not 100).
So far, my bottom speakers would be clear and very loud during a speaker call, but if I later tried to play music, it gets super distorted at max volume and I have to turn it down to about 50%.

What are you numbers that you guys have set for the perfect balance of volume and distortion?
Post those screen shots!

Thanks!
