I won't get into the science behind circuits design, that is an undergraduate course at a uni for electrical engineers (the last head-fi engineer member got kicked out lol) and that always invites people to exercise their argumentative mental muscle but I can tell you that if it started sloping from 100 hz and below, you would definitively hear it by the decrease or lack of bass in that lower frequency range, same argument can be made with the upper end to a certain degree; it is in the audible range. Keep in mind that it is also dependent on the age. When I plug my amp, I can hear the lost of higher frequencies by the smoother sounding highs, and the reduced bass on the lower end, that is why I can plug my highly sensitive SE535 without discomfort on the amp and not out of the HO line. Give it a try and see if it happens to you, if you have different amps then the better because some will clip the band faster than others. You might need to be selective for the music that will emphasize the band you want to clip. Now I did not get into harmonic signals that is another subject for some other threads. But you are right about the design, choice of circuit pcb layout, the tracing layout for grounding purposes and the components themselves all play a role in the final signal.
