Fuses and confusion


I am slowly upgrading my system and I am looking at the changing of fuses step. I have the following in my system:  Sunfire TGA-7401, Marantz AV8805, Carver Load Invariant amplifier, Marantz Ruby, and a Vault 2i. My questions are 1). Which of these components have\use fuses 2). Does changing the fuses invalidate the warranty? 3). Are there videos on changing the videos or do you just pop the hood and start looking. Please feel free to point out issues that I am not aware of and whether this is even relevant under my circumstances. Thanks in advance.

A "shill" is defined in the dictionary as "an accomplice of a hawker, gambler, or swindler who acts as an enthusiastic customer to entice or encourage others." 

So you're saying I'm in cahoots with Ted Denney III. And all my enthusiastic comments, its all just an act. 

Right. I see.   

Now here's one for you: delusion. Look it up. 

Here, let me save you some time:
"an idiosyncratic belief or impression that is firmly maintained despite being contradicted by what is generally accepted as reality or rational argument, typically a symptom of mental disorder."

Replacing a perfectly good fuse with anything claiming to be better is an utter waste of time and money as they will not improve any aspect of a component’s performance. "Directionality" in a fuse makes no difference as none of the wires or PC traces in your components are likely to be installed with any regard to directionality.
@santsuru OP Be smart not gullible, wolf has given you your answer, just stay the path, and don’t listen to any "fusers" here you’ll just waste time and money, save it and upgrade your equipment instead if you have the upgrade itch.

I have a ARC Ref 6 preamp.  It has 3 fuses: mains, circuit board and CE.  Would those who are fuse believers think I should change all 3 or just the mains fuse?

  Two of my favorite fantasies. Fuses act differently when they are wildly overpriced and they can be directional. Wonder if anyone has informed Mr Electron he should be obeying different laws of physics on demand when desired by those with things to sell
Read oldheavymech's reply touting qualifications. Anyone can type what they want and make claims for things that can't be checked. For instance I am a Nuclear Physicist and the first Astronaut to land on Mars where I had to personally maintain all equipment from the 7nm lithographic IC's to the hydraulic motors and lines. Those little 7nm parts were really hard to see but I did it.
