You have to catch up with us younger guys with premature hearing loss. C'mon!!!

 

I usually listen to the stereo at 14-16 for DVD-A tracks and around 26-33 for my iPod (which is docked using a Belkin charger/line-out with a Monster ground loop isolator). Both settings are loud enough for me to really "feel" the music as much as hear it -- the bass vibrates the rearview mirror enough to distort the reflections in it.

Like Kermee said, with all the reports of early hearing loss in the iPod Generation, I'm not really willing to push it too far. =)

 

While listening to music loud, my perfect range for the ML system is 49-53. Upon reaching 63 the system will display MAX, in my dreams I was hoping it would reach 100. I feel Lexus did a fine job to determine 63 to be a safe limit to keep the integrity of the speakers, however for the extra cost from factory to ML, I would expect much louder, crisper highs and a much deeper, richer bass. Bottom line, the ML is worth the money for not having the hassle and damage from installing an aftermarket system.
