This discussion is hilarious. Don't you guys realize you are being made fun of.
I agree, we live in two different worlds. Nevertheless, maybe you’d be kind enough to refresh my memory, How is the test “fundamentally flawed?” Who’s derailing the thread? Is this going to be one of those Geoff Kait death spiral threads? This is just a normal typical audiophile debate in my humble opinion

Would data convince you, though?
Here is the link to the fuse data sheets. Read ‘em and weep. The next logical step for skeptics is to say the test was flawed or the data doesn’t support the proposition of directionality. I anxiously await your rebuttal.

1uV at 1A before the power supply? You are chasing shadows. Any modern power supply can erase that noise. Now, how does that 1uV before the power supply affect the output of the amplifier? There is no data presented in the study. The study just says that different fuses induce some noise. Something that is understood by amplifier designers, that's why the power supply has filters.
Now show me the difference in output through directional wires, that's what I asked for, not some ridiculous study on fuses.

There was some previous discussion on how wire directivity, if it exists, could be measured. Don't know if anything ever came of it.

I’m not sure you’re following me. All wires are directional. The fuse (wire) study data is evidence of that. Can you prove the study is flawed? I doubt it. I can find a flaw myself but it doesn’t change the outcome.
Help. I reversed my cables and it upset a fine layer of corrosion on the tips. Now it sounds fuller and less distorted. What can I do?
No they were measuring a very small amount of variation, milliohms, in resistance over a 1A draw. That could just as easily be because of the fuse holder or the background electrical field. Something as primitive as a fuse will measure differently every time you test it. Heck I get different readings on my voltmeter simply by holding the ends of the probes at the volt level not the mV level! Just because you can measure a minuscule difference in resistance doesn't mean there will be an audible difference coming out of the loudspeaker. There is a much greater difference when you tilt your head than what is being measured in those fuses. The difference in measured resistance isn't because fuses are directional.
The test has no point other than to sell high dollar fuses. How many fuses were tested? How many times were they reversed? Was the test conducted in a laboratory or someone's studio full of electronic gizmos?
You are chasing ghosts. On the other hand you need to get with the power company and check the directionality of the transmission lines.
I'm not so sure that's a good argument. Why would tilting your head be equitable to fuse distortion/noise? Its like claiming IMD can be somehow be equated to linear phase distortion, or something like that. Two very different types of things.
My point is one kind of distortion caused by moving one's head is huge, the other kind of distortion caused by placing your fuses forwards or backwards is imperceptible after going through the power supply, much less through the amplifier and loudspeakers and then played back in a room with the heater running. The effect to the signal chain is well below the noise floor and is probably lower than the heat noise in the electronics. Everyone can hear a difference if they turn their heads, move one loudspeaker even an inch, add carpet, or put up drapes. If fuses were audible don't you think engineers would have fixed the noisy component over the last 100 years of electronic audio reproduction? There are so many things that can be done to reduce audible distortion that produce actual measurable and verifiable results, switching around your fuses or speaker wires is pure madness. At best it's an April Fools joke.
Enjoy the music and stop compulsively chasing shadows.
Having said all that, it would be a great experiment to tell people the fuses have been replaced in this O'Tosh amplifier and it sounds soooo much better. I bet a good 60% would say they hear a difference, 40% would pay good money for the upgraded fuses. People are gullible.

In fairness, I'm not sure that I can, particularly moving my speakers in my room an inch. Perhaps some people can. I'm either really lucky to not have 'golden ears', because I don't pay what I'd consider ridiculous sums for things where I can't personally hear a difference, and I don't spend endless hours tweaking; or I'm cursed because I'm missing out on whatever it is that those golden-eared folks go on and on and on and on and on and on and on... about.
You are not very original. This is already the third thread in which you bring up this jokes. Think of something new to entertain us.
