Mastering92 could-not be more wrong . Having owned a audio store I had the same gear with stock buzz fuses ,and then top Hifi tuning ,Synergistic , fuses
a improvement on every piece of gear , not knowing which dac, preamp,or amplifier
just look up metals resistance index , All power comes in through the IEC and That Fuse , a steel zinc buzz fuse has a conductivity rating around 19
a top Hifi tuning silver gold fuse a rating around 65 that’s 3x+ the conductivity
the stock fuse is a Huge bottleneck which = 3 x more resistance which = noise ,you can ignore the truth , but these are facts just look it up . When you put any non stock fuse inside says an amplifier like my Parasound Halo amp it has 4 rails fuses
that is another level of detail and refinement and Clarity ,the hash sounding stock fuses present when compared directly too , this too depends on the refinement of Your Audio system, if it’s of say $6k including Speakers then. You may not have the Audio system that would pickup all the added low level details , but it will still be cleaner sounding ,For Sure . The same goes for power cords ,wire is not just wire
some people use Blue Jeans cables good enough and that’s fine for a moderate audio system but sonically there is much better for many reasons ,if not so there would-not be such a Huge difference in models even within the same company. The point Is spend time listening for a month and comparing like we do at Our Audio get together to prove or disprove a theory , not everything is a night and day difference . Never Assume ,or go by 1 review look for many opinions ,and look for money back auditions which then cost you very little . If you have not spent several weeks comparing say 200 hours at minimum then , you can’t give a honest opinion .Any long time Audiophile knows once you spend to a certain point , $$ money wise the amount of improvements are diminishing returns . Being a Audiophile for most of us it’s a never ending journey , for tweaks or upgrades !!
