Save your money goofy. If it sounds better you probably had/have "fuse rot" as @wolf_garcia calls it.
The only way a fuse can sound better, if it replaces old crusty one that seen too many switch on surges over time, doesn’t have to be $200 fuse, should be $2 same one but new, and the same result will happen, and switch-on surge ageing will be the same for both $200 fuse or the $2 fuse

Your better off spending $2 on a "new original fuse", and save hundreds.
