Do Fuses make a difference ib sound?

Audio magic thier top fuses I find $300 each a bit pricy ,but after 175 hours a more natural presentation and like them better then the $600 synergistic fuses overall 

Alfred gives you 30 days to audition for a full refund .

Nope. Next question.

My dealer convinced me to try the synergistic research purple fuses in my Rogue Audio. This difference was not subtle. I felt like I had a new upgraded amp. Sound opened up. No idea how it works but maybe it’s akin to upgrading your tubes. Now I have em in my preamp and phono. Like previous folks said, give em a try. 

As with many others on the thread that actually tried them, yes I tried SR fuses with the option to return for a refund and I kept them.  Subtle but noticeable.  YMMV

they make as much difference as changing all of the wiring in your house
