I have experienced in some cases on preamps that have high current analog circuits (such as Class A) or on HT processors with a ton of op amps that a larger amperage fuse will improve things. For example, replacing the standard 800 mA fuse on a Krell preamp with a 2 A fuse will have a good impact. The music just hits with more authority (such as snare drums, kick drums, impacts, etc.), and it is more open as well. It is like the 2A is letting the music breath. With the smaller 800mA, the sound was more constrained and closed in. You want to be careful with how you do this because the fuse is supposed to be there to protect the entire device if there is a short that occurs somewhere in the circuit. On a normal stereo preamp with only op amps, I probably would not go higher than a 1A.
For amplifiers, I don’t recommend bumping up the fuse much because with amplifiers, the 4A to 15A fuses already carry a good amount of current.
And sorry to say, there is no fast way to burn in a fuse. You can always burn the fuse in on a separate piece of equipment.
