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.

@lemonhaze,

I have compared Path to Duelund, Mundorf and Mills MRA.  The Path are the best as they are the quietest and most neutral.  They have an uncanny sense of ease to them. 
The Duelund resistors are good, but compared to Path can sound a tad too brilliant in the upper mids and highs. Same for the Mundorf which I did not really care for. 
The Mills MRA are second best behind the Path. They are pretty neutral and much lower cost if that is a consideration.  
Agreed. Path are the best resistors for a crossover. 
MRAs are more appropriate for amplifiers, and other electronics. 
FM = Fuses Matter.

My scientific empirical evidence.  My ears....that is all I need.

I'm just curious why the Purple Quantum Fuses really? post was removed? Nothing offensive in my opinion. The fuser supporters hadn't even had a chance to respond... I think it should be reinstated.
Sincerely, Doug

I believe it was removed because of this. Threads are closed if they are repetitive. Tammy

fiesta75 Okay, thank you. In my opinion, 3 responses total is not what I would call repetitive. The post was up for a very short time.

I'm talking about the subject of the post not the comments.

Lately, we are getting multiple threads posted about Fuses.
We are just trying to close some where the topic has been covered in another previous thread. Tammy
