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.

I have decided not to change the fuses but for what maybe a different reason than the ones listed above. Firstly I was unable to confirm the type of fuse to switch to and in the process off searching for the correct specifications I was put into contact with Frank Malitz VP of Bob Carver Corporation. He told me over the phone that Bob Carver had said that changing the fuses on those amplifiers would probably not improve the sound. So based on those two reasons I will not pursue this issue any more but I do appreciate everyone's feed back.
Thank you

I wonder how many component manufactures answer that same question all the time. It's probably a recording.

At one time I was involved with electronics repair and from my experience I can tell you that warranties can very from one manufacturer to another. If your device is still covered by a warranty and you see a label or seal over a screw that must be broken in order to remove a cover double check with the manufacturer  before breaking the seal.

Has your fuse blown ?
If so, it is important to investigate the reason why.  When you replace it, make sure it is the correct rating unless you want to make your insurance company happy not paying you for a fire that you may have caused by tampering with your fuses :-)

Otherwise, why do you feel the need to change your fuse ?

Don’t make a blanket statement regarding warranty not being voided. I have an Audio Research amp and preamp and they told me point blank if I use an aftermarket fuse and there’s an issue, it will void the warranty.
