Audiophile Fuses

Respectfully, how do you know for a fact that this is the reason Ayre switched (no pun intended) to a circuit breaker?
Maybe Ayre just did not want people to switch out fuses and inadvertently making a mistake of putting in the wrong fuse and frying the DAC in a power surge or a short circuit situation?
I do not know. I am just saying that unless you do know, then we do not know the reason for the switch.
I am all ears (ah, eyes!). But please explain to speedskater and me why the water storage analogy is faulty.
I am read'in, but I ain't see'in!
How does one fuse versus another fuse add, change or reduce "distortions in the DC" which powers the analog signal stages?
(You and DaveC can feel free to speak technically. I have (had -- now stale) a basic understanding of elementary electronics (from FCC General Class amateur radio license exam).
"Respectfully, how do you know for a fact that this is the reason Ayre switched (no pun intended) to a circuit breaker?"
Because Ayre president/owner Charles Hansen has said so.

Officially, Ayre use a circuit breaker as an overload protection - the case of an overload, the circuit breaker automatically sets the switch to the “off” position.
If so, no doubts!
However I read that the MXR has a lot of internal fuses protecting the circuits.
speedskater, you skipped the step I am trying to focus on: "how is the AC fuse directly in the signal path?"
We cannot just assume the hypothesis if we want to understand this.
Dear Blue58, that is analytically unfair, and it does not advance the discussion. I did not suggest the power cord doesn't and the balanced transformer doesn't and the footers don't. I understand and I can explain why I think those three do matter, even though they are not in the signal path. I am focused solely on the fuse.
I assure you my mind is not "closed." I simply am skeptical and I am happy to be proven wrong based on listening with my own ears, or based on an electrical theory which makes sense to me.
"AC fuse is directly in the signal path; that's a fact; believe me" is not a theory which explains why the assertion is true.
For what proposition are you citing this essay? His main point is that the analogy is incomplete and partially faulty because it does not take into account the fact that electron flow generates a magnetic field, but water flow does not.
How does this critique of the water flow analogy (which I did not think about, by the way) prove that AC is directly in the audio signal path?

I can't explain it, because I don't understand it.
Don't recall ever reading an engineering book that had the AC or DC power supplies as part of the signal path.
The only reference would be to PSRR (Power Supply Rejection Ratio) which is about how well the signal circuit deals with noise in the DC supply.
Most of that noise (and there better not be much) is generated by the bridge rectifier, none by the fuse.
It explains why electrolytic capacitors should not be called "waterlytic" capacitors.
Energy is carried in magnetic and electrical fields.Ron, you should have stayed one extra day at chez moi.
When I dropped you off to get the train back to London, I picked up my SR Black fuses that arrived at work that day.
I’d have convinced you on fuses within 5 seconds of install, in of all places, my Zu sub amps.
Fuses there, in my cdp, monos, have been slam dunk from moment of install.
The only flat moment was the 9 installed in the preamp psu, which have needed a couple of weeks of constant power up and use to bed in (mainly because it appears they are on the low voltage DC rail in the psu, and have stayed cold for longer, and so many of them to bed in). In the last few days, things have gone up a level again.
“Now all is well in audio land again.
Sleep, little audiophiles, and don’t let that skeptical bear Ron put you off upgrading yr fuses”.
LOL.

There is no such thing as "electron flow", electrons do not travel through the wires to your components, (at least not very much). Current is an electromagnetic wave, not electrons moving through a pipe. EEs are taught a simplified view of this because such a view (mostly) works for what they are trying to accomplish. Talk to a physicist to learn what really happens (at least to best of current understanding).
Current is not electromagnetic wave. Photon is electromagnetic wave. Current is a measure of flow of electric charges.
In Maxwell’s equations, current density is represented by symbol J. Electromagnetic wave is represented by E and B.
