No, I hadn't seen that.I will have to measure it for myself. A fuse has resistance and therefore causes a voltage drop, otherwise it wouldn't work (blow when the current is too high) but I don't think that a small voltage drop would cause a audio circuit to sound or perform badly considering that that circuit was designed (operating points, etc) with that voltage drop in place (in mind).
In my proposed test, one might check the operating points to make sure they remain proper with the fuss out of circuit otherwise you might get a false negative.
As for the "duty cycle (on state; commutation) of the power rectifiers in the equipment", I build all my power supplies using critical inductance choke input filters so there is no "duty cycle". Each diode, in turn, are on for their full half cycle so the current through the power supply is constant and just a little higher than the load current.
