I ran the M80's up to 95 to 102. Had to stop there. Too loud, could get painful. I would have to say 85 to 90 would be the limit to my comfort level.

I've worked around jet engines for 20 years and might be sensitive to sharp/loud tones though.

My pain threshold drops to about 75 when the wife arrives home!!
