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.

I have, my system is not "resolving" enough to hear the difference. Or maybe I had it in backwards?😁

Then get a better system. It’s no fun having to listen to a hunk of junk.

My system can resolve waiters dropping off drinks to customers on Live Recorded Jazz albums (glasses clanking on tables, footsteps, small talk in the audience). Every little detail comes through with perfect clarity. Any changes in the audio chain stand out immediately.
It didn’t start out that way, took a couple of years of tuning to get to this level.

I’d say by the lack of resolution of whatever cheapo stuff you are listening to, you have your work cut out for yourself.

Time to leave the toys behind, and graduate onto the big boy leagues.

@grannyring, that's exactly the info I was looking for.

 They have an uncanny sense of ease to them
I then do not need the Duelund's influence going by what you said. I use Mills a lot as I find them a 'safe' resistor to use but as always, looking for and hoping for something great but at a lower price which lead me to the Powertron.

The Path are twice the price but my XO only uses 2 per side. I have long tried to reduce the number of components in my XO designs by eschewing the industries fixation on a flat frequency response which inevitably impacts on other more important areas, and when you add the room's response then the life-sapping extra components are pointless, except if you need your creation to pander to the measurement brigade. When I have managed to find driver sensitivities that match and allow me to forego any resistors, I have found the result to be more 'comfortable' and more immersive.

Oh, and to keep this on topic, I do not use FUSES in my crossovers 😎

Quick question,  what is your guy's experience  with bypassing caps? 
Does it add anything to sound? or just smear it, and cause coherency issues? 
Say Duelund bypass caps, .01uf Silver foil, bypassing bigger caps on a tweeter, or even mids. 
Thanks.
