ShadorneInteresting! My experience is 180 degrees different.
BTW If ever a fuse made a difference then it is time to throw out the pos component. Why keep something so badly designed that a fuse makes an audible difference?
Yup. You got it. Even a basic well made power supply is not going to change audibly with a change of fuse. If it does then you imagined it or your component doesn’t even have a decent power supply.
I hear NO differences rolling fuses in mid to low level BUT hear improvements in high level components. Same goes for cables ...
Began playing with audio fuses years years ago on Sonic Frontier pre / amp and 1st generation Benchmark DAC 1 and heard no differences. Improvements are easily audible in current components.
