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.

Some vendors may well void a warranty if the gear is opened up.

If you modify internals yourself, even just replacing a fuse, there is an even better chance warranty will be affected.

People should always check their warranties (if in effect) to see what conditions apply. It’s only common sense.

Vendors can’t afford to give customers a free pass to make changes then come running if a problem under warranty. It is usually not part of the deal!

Do not listen to anyone who just says "do it", no caveats, with gear under warranty. That is bad advice There may or may not be a problem.

If the fuse you put in is found to be the issue should a warranty repair ever be needed, then that is yet another story. It’s part of the risk you take.

Change a blown fuse or an older tube? Yes you can with no warranty worries. These things are owner replaceable and not meant to only be sent back to the manufacturer.

jnorris2005:
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.

Cheers George
