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.

Unlike you George, I am okay with trying new things out.
If you are right about bypassing capacitors, Trust me I will be the first one to come back here and tell you that.
As I have already said, the .1uf caps did not sound good as bypasses, they muddled up the sound on my speakers, I was not expecting that to be the case.
I am not interested in being right for the sake of being right, I am only interested in things that are true. So if what you are saying is true, I will readily offer my apologies for not believing you.

Fine, I'm hoping what I’ve said helps others trying to do the same. As I've said it many times on Audiogon. 

Cheers George

I added the Jupiter bypass as an experiment to see if the more expensive caps make a difference, and they do.

<<<<<<<<<<<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>>>>>

What about this part george?

They do make a difference, he just suggest a single cap and continues to ask questions, look at what he wrote.

ALL question marks? NOT Statements.. He is ASKING if it might be better, or if it might change the timing.. I say use the same voltage and it won’t. :-)

There is more than one mad scientist around you know.

Well all I can say to you is, forest and trees, you can twist it to suit yourself, and that will be your problem then, and no one else’s.

“ By-passing powersupply or voltage rail caps is a good idea, but it’s not a good idea to bypass caps that are in the signal path as they will have different time constants, and smear at frequencies where they are both doing work.
Alway use the best quality "single cap" in the signal path.”

If economical or physically practicable ^^^^ This ^^^^^ Is quite correct
