There's no difference at all. Explain how there's a difference.Really? You want all of us to go that deep into the weeds to see who can construct the better argument over a faith based perception vs. an empirical one, and have that be the underlying explanation or refutation of aftermarket fuses?
Don't you have better things to do like build that dual mono amp so you needn't try a different fuse?
All the best,
