Why don't amplifier Companies use high end fuses?

Well, as much as I hate to toot my own horn 🎺 I have been saying all along that because all (rpt all) wire is directional, not only are fuses directional but also resistors, capacitors, transformers, and obviously cables and power cords. Also, internal electronics wiring, internal speaker wiring, crossovers including wiring and you guessed it inductors and capacitors. Gee, what about house wiring? Mr. Bedini might have stumbled onto something. 😳 A major discovery in physics, indeed!

There you go again spouting meaningless platitudes. Nothing in this hobby defies the laws of physics. Plenty of people are skeptical of things that don’t actually exist. I like those people. I get worried when I’m around people hearing things that can’t possibly exist.

Calm down, it’s only an expression. But judging from your reaction 😡, an expression that actually has some meaning, you know, inasmuch as naysayers like yourself keep repeating the same mantra: this directionality phenomenon can’t possibly be real, it’s not possible and it disobeys all known laws of physics and electronics. You like people like yourself. 😡 😡 😡 12 Angry Men. 😀

A modest proposal. I propose that hearing and perception are the same thing. There is no real reason to say they are something different. Hearing is a sensory perception just like vision. It's how we perceive realityThis is not to say there cannot be wide variations among even experienced audiophiles regarding hearing ability, experience in listening and so forth. But I think it's wrong to say perception of sound is something other than what we hear as if it's something undefinable or mysterious. Again this is not to say hearing is not complex or even sometimes mysterious. Heaven forbid! And I'm not discounting psychological effects from the whole listening equation, either, things like placebo effects, expectation bias, etc. Nor can we discount listeners' testimony regarding what they hear. It's unfortunate that naysayers frame positive results as some some of delusion. 

Speaking of reality I also suggest that physics, strictly speaking, is not reality in the sense that physics as a science represents what we know, what we have discovered about physical reality. But physics as a science is incomplete, and continually growing. It would be rather presumptuous to assume something mysterious or puzzling MUST be inexplainable by physics. It's premuptuous to assume directionality of wire, disobeys some physical law or even theory. It may very well disagree with what many people assume is understood by science or physics.

From intro to Zen and the art of Debunkery:

Seeing with humility, curiosity and fresh eyes was once the main point of science. But today it is often a different story. As the scientific enterprise has been bent toward exploitation, institutionalization, hyperspecialization and new orthodoxy, it has increasingly preoccupied itself with disconnected facts in a psychological, social and ecological vacuum. So disconnected has official science become from the greater scheme of things, that it tends to deny or disregard entire domains of reality and to satisfy itself with reducing all of life and consciousness to a dead physics.


As the millennium turns, science seems in many ways to be treading the weary path of the religions it presumed to replace. Where free, dispassionate inquiry once reigned, emotions now run high in the defense of a fundamentalized "scientific truth." As anomalies mount up beneath a sea of denial, defenders of the Faith and the Kingdom cling with increasing self-righteousness to the hull of a sinking paradigm. Faced with provocative evidence of things undreamt of in their philosophy, many otherwise mature scientists revert to a kind of skeptical infantilism characterized by blind faith in the absoluteness of the familiar. Small wonder, then, that so many promising fields of inquiry remain shrouded in superstition, ignorance, denial, disinformation, taboo . . . and debunkery.

Really??? 2-3db difference in absolute volume because of changing the direction of the mains fuse? I’m stunned and speechless.

All you need to do is to try it. That's all anyone who doubts this has to do. Until then, you're just knocking your head against the wall. 

I get it. People who are deep into this hobby and "know it" inside out, have overlooked something very simple: the fuse. Imagine all the amp builders/designers out there, laboring away at their craft, scratching their heads as to why, despite reading all the manuals, following the schematics, they end up with something that doesn't sound quite right.

So they get inventive. More NFB here, less there. More shunts and chokes. Tinker here, tinker there. Change this, change that. And like a child of their own, no one can tell them it can be improved.

Then along comes this schome who has a hard time putting a battery in a remote, who swaps out a fuse and all of a sudden, maybe they didn't have to do this, or that, to get better sound.
I get it.

All the best,

I might argue, while agreeing with you in context, that hearing is a 'sensory function' , perception is what a particular individual experiences. 
Let's take the 'fuse' improvement hypothesis for argument's sake.
Generalizing that those who do not change the fuse, or power cord, are 'missing out' is a huge assumption. When 'you' in fact may be the one missing out from what someone else hears using a 50c fuse.
You can't get around perception. Without it, our brain would not be able to 'fill in' small details in a variety of stimuli. Obviously, the condition of our sensory organs is also a player. 
There are so many factors related to our acoustic environment, personal physical condition, like an individual's perception, that changing a fuse is a drop in the proverbial bucket when it comes to hearing an improvement that can be shared. Notice I said, an 'improvement'. I will not argue that there can be a 'difference', no matter how small, even measurable. 
I will go one step further, if the only variable is listening the next day, in the same exact physical environment one would perceive a difference just based on their personal condition, like brain chemistry at that time. IF you want to argue, leaving everything the same except either the fuse or power cord, etc., will also provide a noticeable difference of the same magnitude, then that's fine. I can argue about the physical world, but never about perception. If you hear it, and you like it, that's all that counts. All the rationale and explanation need not take that from you. I know I am not disagreeing with the Flat Earth Society here. Whether it's an opinion, or a perception, it is always our own.
