1. Do you think designer fuses are A) a Gift to audiophiles, or B) Snake Oil
answer: c) somewhere in the middle. Expensive to be called a gift. Also it is not even of any value to talk in general about sound quality of "designer" fuses. That means just appearing fancy and being expensive. I do think some fuses work better than others and there are many that work extremely well that are not "designer". There is a definite snake oil factor. There are rational ways to choose a fuse like any other electrical component. You can choose just because you believe nothing more.
2. Have you ever tried them? Yes or No
Yes.
Well, they can’t be much of a gift if you can’t hear them. It’s much better in cases like that to use an inexpensive Littlefuse or Busman fuse and be dine with it. Audio Nervosa is not good for anyone. How do you know if some fuses work better than others if you can’t hear them?
