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.

Many of you don’t know what a fuse does.

The AC mains fuse is supplying mains voltage to a transformer, which then supplies lower AC voltage to the AC to DC recifcation diodes, this DC is then is sent to the voltage storage capacitor banks. And the amplifer then draws it’s DC power to work with from that storage bank of capacitors, which if designed right don’t ever run out of storage.

EG: Try to look at it this way.
Your using you home water tap (amplifer) from a dam (Capacitor storage banks) of water which never runs dry.
Your home tap does’nt give a ratz, if the clouds that supply the rain to the river that fills the dam, is raining or not, so long as the dam has water in it, the tap is doing it’s best an happy.

You can believe whatever you want, it’s a free country (I think). I am just reporting what I am hearing.
Dam/ water/ whatever else, I have all these fuses on hand, and it takes less than 30 seconds to swap them out on my DAC. I am hearing what I am hearing, and it has been confirmed by all my friends that have come over to listen to my system as well.
I don’t pretend to understand the physics behind any of this, and honestly.... I am not all that concerned about it either. I have a few theories, sure, but I can’t conclusively prove anything.
I thought a fuse was a sacrificial safety device that melts during an overcurrent condition to protect an electrical circuit. So isn’t the role of a fuse to melt if there is too much current in order to protect an electrical circuit/device? 
And power cables just bring AC to your equipment, and conditioners are just useless junk.......
we can do this all day :)
Try bypassing your fuse for 5 minutes and see if the sound coming out of your speakers changes. (try a 26/28 gauge of copper  wire)
It’s a very quick easy experiment.
For sure it is belief, and not knowledge, because water pressure definitely does affect how much water comes out the tap. Total logic fail. As usual.
