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.

@ squeak_king_77  This is regarding a stock fuse and remember I mentioned trying to trick my wife by not reversing the fuse and she was expecting to hear a change for better or worse but admitted that she couldn't hear any difference on that occasion.

The change is small with a stock fuse but we are not arguing magnitude of change but only that there is a change. Individually I don't know if I could enter the room and identify the direction of a single fuse, however if all the stock fuses have been correctly placed then I could.

Swapping all the fuses and then changing them back is very disruptive, not gonna happen. I do not need to prove anything to you nor anyone else. I heard what I heard. It was this revelation that lead me to seek better.

This is not about me, its for the arrogant and ignorant who without trying for themselves claim, snake oil, rip off and don't waste your money etc.

If the fuses are of higher quality then the game changes.

Have you tried it and if not why not?

@ squeak_king_77  No problem, you are someone I would welcome feed back from. I have just one SR Blue in my DAC. I had 3 such fuses at one time but found the detail resulted in a slightly over the top edge to the sound. Certain female vocal would make me wince and generally the overall effect was a bit splashy and sibilant. Hoping to find a fuse that lowers the noise floor but without adding anything.
