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.

The Fuse
To my ears a simple fuse can make a difference ,
but does the difference justify the cost ?
I found going from a glass fuse to a ceramic one is an improvment 
the I highly recommend , when I purchased a Furutech fuse 
( for 1/2 price ) I did hear a slight improvment but the wallet
questions $2 verse $35 .
I use Bussmann fuse for the other 6 I'm the amp and 2 in my phono preamp' power supply . 
I am going to try 2 gold HiFi tuning in my amp because they are
on sale for only $13.00 and maybe my phono preamp power supply . 
So open your wallet an try what you are willing to spend  .

Albert Einstein formulated the " cosmological constant "
and yet today we know that not only is it expanding but
it is also expanding at a faster rate rather than slowing down ,
something that defies physics as we know it !

So when one asks for help or an opinion about our hobby 
it is disappointing that the discussions seem to expand into 
back and forth childish behavior .

You either hear a difference or you don't period !
Say so and move on .
