I was going to say the one that sounds better to you but your suggestion of listening without a fuse for a short period of time as a reference for accuracy ain't such a bad idea, unless you get addicted to it.

Follow Ups:
Yes, that would be a problem. Running your gear without fuses would be dangerous. Running your gear while paying close attention, in case something goes wrong and you can pull the plug real fast, is one thing. Running your gear day after day without fuses is different and would not be smart.

Ralph, from Atma-Sphere, gives a fuse "sound" explanation, which he attributes largely to voltage drop. (link below)
I've threatened to try his experiment more than once, but always find something more pressing to do.

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.

That's what bugs me, when proponents of very expensive fuses wax profound on the myriad ways in which the sound improved. The superlatives that get thrown around leave me bewildered and skeptical. How bad must the system have been beforehand that SQ improved profoundly and in such minute detail? I'd prefer it if someone said they liked the sound a little better with fuse X vs fuse Y. And leave it at that. Because I am usually very pleased with even a small uptick myself.
Expensive, cheap or very expensive, fuses make a very significant difference, huge I would say. Enough so that everyone here should be trying a few out for themselves. Even if it's a "small" difference it could be of a type that is very important to the listener.

I can't imagine there being a significant difference in voltage drop either, but never having tried it, I really can't say if it would make a sonic difference. You can't beat "free" though, so it's worth a try.
I included Ralph's comment because he seems to do a decent job of straddling the objective/subjective fence, and that's the only time I've read anything about why boutique fuses might work (to improve sonics) rather than the totally subjective "I don't know, but they do" camp.
