Any of you 15" MBP owners out there have problems with your speakers. I'm not totally satisfied with the quality of mine. When I reach the third loudest setting and on, the sound gets distorted. Like the speakers can't take the volume. Watching videos, playing music. And I didn't change the volume settings in the respective programs. My 15" PB had no distortion what so ever, even at the highest setting. It could even play louder. So you guys have the same problem or is it only me?
