Why don't amplifier Companies use high end fuses?


My equipment - Raven Integrated Reflection MK2 tube amp 58wpc. / Lumin A-1 DAC Streamer / Synology NAS / Isotex Aquarius Power Conditioner / Furutech Rhodium Plug / Sonus Faber Amati Homage Tradition speakers.  

I have read thousands of comments on upgraded fuses improving the performance of sound.  I am very open minded but not sold either way.  So, the question I have is....if fuses were so important, than why don't Amplifier companies all install them as OEM equipment?  To me, if they are as good as people say, that would provide companies who use them a competitive advantage?  

Every High End Audio store I go to in Phoenix have told me it does not make a difference and is a waste of money.  For the record, I have fuses purchased at an automotive store for under $10 and I think my sound is awesome.  The Company that built my amp tested the Synergistic Fuses and he emphatically said there was no difference.  

If I were to try a fuse for fun, given my equipment, what would your recommendation be to try?

While an amusing anecdote that Conrad Johnson story doesn’t actually mean anything. The same thing can happen for regular stock fuses. It’s because either the amp is not conservatively rated or because the customer makes a mistake. it certainly can’t be true that the AM fuses is always the problem. Of it doesn’t make sense it’s not true. I'm a ten minute walk from Conrad Johnson as we speak. If you like I can over and straighten them out.

Have a nice weekend 🌞

"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 might convince yourself or some people with that argument but not me. Once you experience it yourself and experience cable directionality yourself there’s no going back. I mean, unless you wish to be in denial.

"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."

>>>>>I agree. That’s why I say perception of sound is the same thing as hearing. They are not two different things. And of course the brain is involved with the perception. That’s not exactly news.

"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."

>>>>>Once you experience it yourself you will/should change your expectation to account for your new perception, no? Unless you experience it yourself you’re just guessing.

"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."

>>>>I disagree. The weather, time of day, and things you might have done to your system either on purpose or accidentally as well as other variables must be accounted for. There is also break in and warm up to consider. It is certainly not black and white as you suggest.

"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’m not saying any such thing. You are.

"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."

>>>>I’m not talking about personal preference or some vague thing that can be interpreted any old way. I’m taking about something that is physical and that is very noticeable. I’m talking about physical reality, not some philosophical argument about reality or perception. That doesn’t mean some people will not hear it. But most people do hear it. Thousands of people have heard it. That’s the preponderance of the evidence in this case. You can throw away the negative results. They're outliers. Case closed.


>>>>I disagree. The weather, time of day, and things you might have done to your system either on purpose or accidentally as well as other variables must be accounted for. There is also break in and warm up to consider. It is certainly not black and white as you suggest.


What I meant is if you could hold or control all the variables except the human one, there could be a noticeable change from one day to the next. Sorry, if I was not more clear.

But If you know in your own mind it really works, then there is nothing to argue about.

But generalizations like ’most’ and ’thousands of people’ means nothing to me without empirical evidence. If highly regarded artists as well as audio and recording engineers were also to support it, I would certainly consider it more seriously.

There are scientific studies done that prove differences between reality and perception. It is not philosophical.

And there is very much science is not aware of or cannot measure or explain...certainly including sound and human hearing
