Fuses


I’ve read of views on whether amp fuses impart any sound quality or coloring. I had a recent experience that has made me re-think my views (fuses do not affect sound) and wondered if others had a similar experience. 
I have a Line Magnetic integrated amp. After heavy regular use for over 5 years, one day it just wouldn’t power up. After checking the power supply, I assumed it must be a blown fuse. I recalled that Line Magnetic sent with the amp two replacement fuses of the same type/quality that was pre-installed. I dug out one of them from storage, replaced the fuse and the amp powered up normally. 

What surprised and delighted me was the change in sound with the replacement fuse. Fuller bass, more detail and more warmth. I have rolled the tubes several times in the amp, and am attuned to the subtle changes that can make. Popping in a fresh fuse seems to have had a similar affect. And these appear to be cheap fuses, available for a few dollars at most. I don’t think I understand any of this.

“ Ordinary fuses are designed only to fail, no effort whatsoever goes into trying to get the most linear response possible at all points up to failure. Reasonable then to expect ordinary fuses to get hot a lot, and change resistance a lot, even well before failure.“

As you have decided to use a hint of sciencey speak where are your measurements published that record this improved linear frequency response for the QSA fuses that you are endlessly promoting ?

I cannot find any measured test results of this sort published on the QSA or Synergistic research web pages for their products.

where are your measurements published that record the relative temperature response under load to back up your assertion that QSA fuses respond differently in this regard to a standard Bussmann fuse ?


I don't understand it, therefore it can't be true, therefore I refuse to try it.

Think I got it, @tsushima1 

Your argument would be better served if you actually had any experience with the subject at hand.

Come back after you've tried a couple of fuses in different components, and let us know what you think. I think most offer a money-back guarantee.


Your rather weak attempt at deflection has absolutely no connection to the question that I posed , I am asking to see Empirical evidenc to back up the statements made above that are entirely measurable and not subjective ... have another go
@mitch2,  thanks for the thoughtful post. I attempted awhile ago to put something up but could not find how to do it. I have right now clicked on my profile but see no mention of 'Audiogon Virtual System'. Can you assist please?

To some geniuses "Science" only means some corporations hiring a team of "experts", who do a bunch of measuring, poking, prodding....etc etc etc.
when they scream science, they mean "Mega Corporate Science"... Unless you have Billions of dollars backing up your point of view, that view is not valid, no matter how much anecdotal, or personal evidence you might have.
It’s a religion of "Mega Corporate" Science worship, only extremely well funded Priests in white robes need apply, and their proclamations can never be challenged by the likes of us non sanctioned fools.
Corporations are the Church....and Science is the new Holy Spirit. One cannot exist without the other.

They forget that nearly every major invention of the 19th and 20th century was made by some dude in his garage. with the mindset these people have, planes, telephones, computers, radios, TVs, cars, phones, lights, electricity would never have been invented or discovered.

"If you cannot measure it....it does not exist."
Albert Einstein


Actually these are the real quotes

„The mere formulation of a problem is far more often essential than its solution, which may be merely a matter of mathematical or experimental skill. To raise new questions, new possibilities, to regard old problems from a new angle requires creative imagination and makes real advances in science.“ — Albert Einstein

„One thing I have learned in a long life: that all our science, measured against reality, is primitive and childlike—and yet it is the most precious thing we have.“ — Albert Einstein
