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.

Your amp’s fuse holders have a screwdriver slot, in the cap (if it’s the typical Sunfire Load Invariant).    Do not try to unscrew them.        As MC stated; push in and turn counter-clockwise, 90 degrees.           I’ve had to replace a few fuse holders, for the uninformed.

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.

Thanks for everyone's help. I was able to poke around and figure out how to get the fuses out and copy down the markings and put them back in without blowing up components or fuse.

Then try one purchase at a time. If you can't hear any difference wtste your money on something else.
