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.

Brad, it is very easy to fall for this. I think most of us have at one time or another. Many here obviously still do. You can not evaluate sound quality this way as your own internal biases can affect the outcome even when you are sure they can't. In short, you can remember what you heard but you can't remember what you heard sounded like even if you attempt to characterize it. It is impossible, none of us can because out brains are not wired to do this. People are dead certain there heard a difference which births the mythology and an industry base on psychological deception.

To do this correctly you have to go switch back and forth between the two possibilities. When you do this you will realize you can not hear a difference. Since this is difficult to do under most instances without special equipment it is hardly if ever done. The reviewer's certainly won't. That would be like politicians voting in term limits.

Your initial instinct was correct. Stick with it.
 
I don't believe I've ever read where someone practically commands another to not hear something and to only believe what he tells them.
Amazing.

All the best,

I don’t believe I just read another fuse thread that said all the same things that every other fuse thread has said.

Guess I will never learn

@juviarora,

’t wasn’t me; someone else must have taken offense. That said, your riposte to my gentle ribbing was kinda gross.
