Determining current flow to install "audiophile" fuses.

I’m going to develop and market an audiophile grade bi-directional fuse and nip this thing in the bud. With this product, IT WON’T MATTER AND THERE WILL BE NO UNCERTAINTY! :-)

We've already got one!

27 years ago we recognized that fuses can affect the way our equipment sounds. At the time, there were no boutique fuses, but we sorted out a fuse that in fact did sound better, and designed the sheet metal for our MA-2 to accommodate it. We still use this fuse today; interestingly enough it sounds better than the boutiques we've tried and it does not cost as much, although its not a cheap fuse by any means. However it must be built pretty well as reversing it in the holder has no audible effect whatsoever.

27 years- does that make us one of the first manufacturers to recognize this phenom? I think it does.

FWIW the stock slo blo fuse that came in my ARC sp16 appears to have been well thought out to start as well. It is quite substantial and unique in its build compared to most common slo blow fuses I have seen over the years.

How much a "good sounding" fuse need to cost is a whole other can of worms. Slo blo or otherwise.  It can cost as much as someone is willing to pay based on it "sounding better"  even if for totally unknown reasons.  

So its not a given that all high end vendors just shove any old fuse in there to start with. Good vendors tend to think everything over pretty carefully.

Another reason to not generalize and say fuse X always sounds better. What one starts with is certainly a factor as always. No mysteries there. A change in one case is not the same as in others.

Also interestingly the fuse is not symmetrical in its build which is obvious to the naked eye (unlike crystal patterns of metal) and reversing that does nothing as well.

Geoffkait wrote," You cannot extrapolate or generalize your negative results to make some grand statement such as, "I tried the fuse and didn’t hear anything, therefore it doesn’t work."

To which Mapman retorted,

"Well I did try reversing directions and heard nothing so yes I can."

I know you’d like to be the Lone Ranger in this but actually your test means nothing. Obviously it means a lot to you. Just not to anyone else. Negative results in any experiment can be easily explained any number of ways. Shall I expound on that thought?

Mapman had these afterthoughts,

"Don’t be scared......

You’ve done nothing but run your mouth."

Ouch! Very ouch! (One imagines it’s not much fun being an outlier.)

PS for Atmasphere: time to catch up to the 21st century. A lot has happened in those 27 years. We have quantum chips and everything! ;-)

I know a person who works for a world know company. He was with some collegues in England at What Hifi. When they wanted 5 stars for their product they had to pay an amount of 4 digits.

At the end they didn’t pay and they got 3 stars. Tests often doesn’t garantee you anything.

The question is; when is a test objective and honest? I know many products with great reviews who were very poor. And also products with average reviews who were exeptional good.

I think you need a new and different way of perspective to judge audio products. And you know why?

Because they way it goes now in 10 years the audio market will decrease for sure.

It is not the question if it needs to change, but how because you cannot wait too long!

" uch!  Very ouch! (One imagines it's not much fun being an outlier.) "

You are not even that.   Just a cheap vendor who likes to run their mouth.
