Yes, current limit IS a real and big issue. Maybe first test on a low-current device. DAC? Phono preamp?
But won't this conduct thru only one leg at a time....and if a fuse is in series with that leg, make the directional nature of the fuse more apparent?
And yes, the voltage drop IS a problem and may be visible if you look at the output on a scope by some 'notching'?

Follow Ups:
The result would be something similar to crossover distortion in a Class B amplifier.
One diode turning on and the other turning off is not something that happens without a finite delay.
Since your premise is incorrect, there's no need to fabricate a highly flawed test to 'prove' it. Fuses do not have a "directional nature." Period.

I don't believe in fuse direction being a big deal....or any deal....either.
But if testible by those who believe? they should do so if possible in as blind a fashion as possible so audible differences will be the indication....
And yes......I see what you mean about crossover distortion / 'finite' delay.......
In my panels? If I was concerned, I could eliminate half a dozen connections and the fuse in the CROSSOVER....on each panel. I've heard some persons use those ceramic, filled fuses instead of glass.....

I actually use 25amp SSRs on my power amp sequencer. Can't have 6 large power transformers coming on at once. Yes there's a voltage drop and the SSRs do need some minimal heat sinking.But I am hardly worried about a 0.7 volt drop at a nominal 115 volts. And these amps run about +/-55 volts on the DC rails so it's a 0.7v drop on the DC rails as well.
