"actually think it makes a lot of sense that the fuse is important as it is. The best way would be no fuse at all but can’t do that. So considering all power comes through that fuse, before i spend 1000 dollars on a power cord, I should probably take a look at the power fuse.."
Not to be repetitive but some reasons why the fuse is actually critical include but are not limited to it’s exposed to RFI, it’s exposed to vibration, it’s exposed to magnetic fields, it’s a conductor, thus purer and/or better metal conductors and end caps are audible. For starters I would specify 5 nines silver or 7 nines copper for the fuse wire, end caps and the fuse holder. It's not rocket science, folks.
