Determining current flow to install "audiophile" fuses.


There are 4 fuses in my Odyssey Stratos amp. I recently returned some AMR fuses because they rolled off the highs and lows a little too much for me. Mids were excellent though. Anyway, I'm getting ready to try the Hi-Fi Tuning Classic Gold fuses, as they are on clearance now for $10/ea. Are they any good? However, I have read that they are a directional fuse? Can anyone confirm this? If that is the case, does anyone know the current flow for the Odyssey Stratos? Or, does anyone know how figure out current flow by opening up the top and looking at the circuitry?

Well, this thread is a test.
I read the whole thing in one sitting.
...This means I failed the test.

I am starting a web site with the sole intention of fleecing gullible people into sending me their money to pay for magic rocks. Seriously, I will be a genius and a thief all at the same time. Actually, wait... only a thief.

I think the argument is not so much about being possible or not, more so how much whatever might be reliably discerned about fuse direction to whatever extent it might exist matters.

Some say it does and some say it does not.

My personal opinion is if it does matter its way down on the list of things that I know for a fact matter.  Below things like even the robustness of the contacts/fit of the fuse as Atmasphere has pointed out based on his experience.

Everyone is entitled to an opinion.  Including discounting the opinions of others even I suppose.  The question is always how much water does any one opinion carry.

Uh, problem is its not his experience,. Its  just  the old ivory tower academic type thing in action.

Look who’s talking!

Atmasphere actually designs and makes highly regarded amplifiers using fuses.

What is your experience exactly that puts you in a position to question his?

Theoretical physics?

That’s fine but the problem is its well, just all theory.   You know, just the old ivory tower academic type thing in action.

You do get points for Chutzpah though.

But wait, isn't thief genius?

No- its the willingness to acknowledge that people hear something (the 'ivory tower' type would have written it off as expectation bias or swamp gas), and then find out why.

Ah, so you've heard the difference in fuse contacts? Maybe you mean someone you know.  ;-)

Cleaning the fuse contacts might make your fuse do its job a little better, and the otherwise magical effect a 4000% profit margin tiny wire (an SR black fuse for example) is certainly El Placebo a Mundo. Putting a $112 sandwich on your gear would likely do the same, but at least later you can eat the sandwich.
Wolf_Garcia, you are wasting your time. I took EE cources and took enough more physics courses to get a major. I know physics has not totally mastered natures laws, so you cannot say there is no physical explanation in EE for why fuses would differ. But the expensive SR Black fuse are both expensive and work quite well. Today I'm going to change the direction of the five of them in my line stage and amp. I am going to go with the best sounding direction.
That 112 dollar sandwich may or may not taste good (for that price I hope it does). Taste good or not it won't improve the sound of an audio component. The good news is the SR Black fuses have improved sound quality for "many" experienced music lovers on this forum. Tbg  you're right, there are numerous observable phenomenon yet to be explained by our current knowledge of physics.
Charles,
Tbg  you're right, there are numerous observable phenomenon yet to be explained by our current knowledge of physics.
This is true, but if you've not tried to correlate that voltage drop across the fuse and its holder, you don't know if a simple explanation is the cause.

IOW assuming that what you hear is due to some sort of woo factor without trying a simple measurement is likely going to result in an incorrect conclusion.

This statement seems self-contradictory. Is this really what you meant to say??
Note the quotation marks around "many." How telling. There isn't even any actual evidence that SR "quantum tunnels" (man…nice choice of terms there SR, as not only does it not make sense, it sounds great!) anything with their silly claims of having their Chinese factory treat this tiny wire with "2,000,000 volts" of unobtainable juice, any rational explanation of why they would do this, or why the ratings on the fuses is apparently dangerously incorrect ("buy the higher rating just to be sure it works" has actually been suggested by the promoters of what is essentially a safety device). People's imagined claims that these fuses do something and then do it better reversed should be regarded as the weirdly imagined nonsense that it is, and the rabid promotion of these products by a few zealots is a shameful fraud. Buy a reliable Littlefuse and save the 100 bucks for some sandwiches…you'll feel like everything sounds much better...

+1 Wolf, pure voodoo.

And as Ralph say, it's "expectation bias", and that's all anyone gets for $100, except the seller, he's laughing all the way to the bank.  


Cheers George

Reading all these INSANE claims about audiophile fuses / directional fuses has convinced me that I'm in the wrong business. I could literally be getting fused knocked-up in some Chinese factory for a few cents each and sell them to the gullible "audiophiles" for $30 each. And you know what, while it would be a complete bunch of snake oil, the crazy audiophiles would be happy with their black & gold colored fuses, their brains would somehow hear a difference, and we'd all be happy. So, I COULD actually live with myself/sleep at night!

Never a truer word said, also AC is Alternating Current, which changes 60 x a second, or 50 down here in Au.

Cheers George

Don't even think about all those cheap stock fuses and interconnects, half of which were installed backwards, on the way from the performer to the recording if you ever want to sleep at night!

Thinking of replacing all of my fuses with 1 1/4"  OCC copper rod......  should sound great.   Hi end fuses are probably the biggest scam in all of audio.

Hi Ralph, 

 

Thanks,  I would never really do that.... I just think the whole fuse thing is silly.  I ALWAYS use the exact type O.E.M. fuse .   

Yup, fire for sure if you have not oriented your copper rods in the proper direction😎
