All too often, the sound you hear at a rock concert can be heavily distorted, especially when it is loud. In many instances, that distortion is deliberately induced, because people think it sounds "cool". The distortion may arise from the acoustics of the space in question, it can by caused by the electric instruments being used, and it can also occur if the sound technicians at the concert overdrive their amplifiers. Distorted sound at 90db can be excruciating.
By contrast, when you listen to a well-produced recording at home on a great stereo, the relative amount of distortion in the music you hear will be low. In fact, if you don't over-drive your amplifiers, (and allowing for the acoustics of your room), the only distortion you should hear should be that from the program material to which you listen (CD/record/tape). Under those circumstances, you should find that your stereo still sounds great even when I play it at high decibel levels.
