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.

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.

>>>>That’s not logical, Captain. We already know that distortion measurements can be deceiving. We know for example that many Tube amplifiers with say, 0.05% Total Harmonic Distortion (THD) sound MUCH BETTER than many Solid State amps with vanishingly low THD of say, 0.001%. AND some tube amps sound better than other tube amps that have lower THD. And so forth. So, the logical conclusion here is that - all things being equal - distortion is relatively meaningless. Good sound is definitely not DEFINED by very low distortion. As for me I’ll take good sound over low distortion any day. 😬

@geoffkait

It is totally logical. There is nothing deceiving about distortion - no distortion at all means input and output are identical and that is the holy grail of high fidelity. Some distortion measurements specs may hide or ignore important aspects of distortion (odd harmonics, zero crossing distortion at low level) but that does not diminish the overal goal of ZERO distortion in a high fidelity setup. This means a high fidelity setup is not going to be audibly affected by a mere fuse - otherwise it is a real pos in terms of high fidelity!

A designer/manufacturer can design primarily for an old 60’s tube sound with archaic technology and tune by ear to decide what flavour sounds the best

or

a designer can design primarily for high fidelity using latest technology and use measurements to prove it by testing the power supply robustness, channel separation, distortion, SNR etc.

What sound is preferable? Well some prefer high fidelity (at the cost that you hear the recording as it was produced - warts and all) and some prefer euphonic glorious coloration that just presents everything in a way that sounds better than the original recording to them (at the expense of robustness, reliability, accuracy and some finicky equipment behaviours from older technology)
