Angela touches upon an interesting point, although the issue, I believe, is not the danger of the amps working really hard at not delivering the current, but rather, the amps not being allowed to work hard enough to be in a confortable, never mind ideal operating range.
Every component has an ideal operating range, and while I agree with everything that has been said already as concerns the issue of potential damage, the matching of components with concern to this issue is IMHO one of the keys to really musical sound from a system. It's kind of like my SAAB Turbo; at 25 mph it's great, but at 50 mph+ you just sense that the motor is happier and performing at closer to full potential.
