Expectation bias can be overruled by actual listening experience if one approaches with an open minded attitude. Generally the better something is the more it will cost. There are without doubt exceptions to this generality especially in High End audio. Higher price and performance don’t allows go hand in hand. The Create Audio fuse could be better or equal to the SR Black for all I know.
Problem is who determines which is better? Same answer as always, subjective, so better remains in the ear of the beholder/individual. No upgrade fuse is going to sound better than a stock fuse to someone convinced that it isn’t a possibility in the first place. Again expectation bias.
