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.

Then use one of these in place of your fuse for just a test instead of spending $$$ on snake oil fuses, and see what it sounds like compared to the normal fuse, as it’s solid brass fuse buss bar just like no fuse at all for tech testing.
georgehifi UGH!~!! But, what about the atom structure and purity of the brass?!?! Is it directional?!?!? Do you need to clean it weekly and coat in some special secret sauce?!?! (Just teasing). I can see making a pretty penny on making some different brass buss bars! OCC copper, titanium, adamantium, unobtanium, hand forged, cold treated, etc.

I wish science and technology could discover a way to measure and catalogue the tint/hue changes each components makes. I worked in professional photography for years with most of it using large format chrome film. It was ’easy’ to measure and know exactly what the tone, tint, color, hue and contrast changes a piece of film would have by the chemistry used to make the film, temp and time kept in storage to age, etc. But electronics man.....a watt isn’t simply a watt!

Good luck with your brass rods. 
I am finished with this conversation as well.
Thank you

The best fuse is no fuse, we already know this, but most equipment does not allow for the installation of breakers (and breakers also have their issues)

This is not a breaker it takes the place of the fuse with a solid brass rod (No fuse then). just like bypassing the fuse altogether. Best you can get by your views for a couple of dollars🤦‍♂️

@millercarbon  what is your opinion on bypassing crossover capacitors?

I can't take George seriously anymore, would love an answer from someone that has actually tried the stuff they are talking about. 

I am thinking of bypassing a tweeter cap with a .01uf Duelund Silver foil cast.
