Any component change in the signal path is easily heard and to say a fuse will not change or benefit the sound of circuit shows that one thinks or says so suffers from the Constipation Blues in the area of the brain
Please name even one of todays quality amps that use CD rail fuses?
I said DC rail fuses in an amplifier, are totally useless and are even detrimental, no matter how much they cost, no hi end amp these days of any note use them, only the some old junkers from yesteryear did, and you can even put speakers into that as well as they are fed from the dc side of an amp🤦♂️
BTW lets name any of todays noted quality amps that use fuses in their DC rails?
