.....for a bad design. And by definition, something so prone to such a nuance back behind the power supply is a poor design. The entire point of a power supply is to filter noise and smooth the incoming power. The ideal power supply provides the rail voltages and current the circuit requires with no noise or perturbations. By saying a single fuse made that kind of difference, one is also saying the power supply was garbage. All you're hearing in a stereo is the modulated output of a power supply so it better be good. That's why good amps have very robust power supplies resistant to all kinds of garbage. In a good amp, it's the most expensive thing, second to only some of the ridiculous chassis some build, like D"Agostino.
