Synergestic Black Fuse vs Audio Magic BeesWax

Huh? Change fuses every 6 months? That don’t make sense, partner. Heck, that’s hardly nuff time for the Graphene to break. 🤠

David,
I do appreciate your comments regarding me, thanks.
Joecasey’s comments above referring to the quality of components and their response to upgrade fuses mirrors mine. The higher quality audio components do in fact display a greater difference and noticeable improvement in the sound quality. David Pritchard above just reported his + findings with the Blue fuses in his new Pass Labs amplifier.

I believe that this type of outcome has been the "overwhelming " rule rather than an exception. The power supplies in Coincident products are  indeed excellent. As are the power supplies of the numerous brands used by many very happy upgrade fuse users who have posted on this forum.
Pass Labs
Audio Research
VAC
Atma-sphere
Art Audio
Concert Fidelity
Absolare
Shindo
Vitus
The list goes on.

Would someone care to make the case that these established and esteemed audio products lack high quality parts and power supply and this makes them "susceptible" to upgrade fuses? This argument is absurd and is bereft of logical reasoning though some persist in repeating it to the point of boredom.

Or is it simply expectation bias, really? This explanation would sufficiently account for similar results involving many individual listeners and also a wide spectrum of brands and components? Again it doesn’t pass the logic test in my opinion. There have been a few people who heard little or no benefit (this could be said for the any audio product) this is reasonable to me. A very large number of listeners have reported very favorable experiences.

Well your experience suggests that what you regard as high level components don’t appear to be all that reliable and robust.

It depends on your definition of high level - does it mean high fidelity (in which case a mere fuse should not affect the audio) or does high level mean an expensive boutique custom item that was built and tuned by ear to sound great but without an emphasis on low distortion and elimination of extraneous factors (like a mere fuse) affecting the sound quality.

I am sure everyone can agree that it is actually possible to design a very robust power supply that has more than enough stored energy (for transients) that slight differences between one fuse and another won’t affect the sound. Once you accept that this can be a design goal and is easily achievable (adds only cost but presents no major technical hurdles) then it sheds a new light on components that are finicky to the point that a fuse makes a big difference....
