  • Fuse holders

    You can read a lot about high quality fuses on almost any audio forum, but what about fuse holders? IMO these (should) matter too. The "problem" is, I can't find any information about existence of quality fuse holders. Are there any?

    ...the less trash metal you have in the signal path and the AC line the better the sound will be. I do have the same fuse holder on most of my Equipment but I am not sure it would be worth for a manufacturer to produce something intricate like that, as there are to many models it would not fit on.

      A fuse holder is simpler than a fuse. As long as its near zero ac and dc impedance, it should be good enough.

          I knew you can change the whole inlet to something better but I had no Idea someone makes high-end Fuse holders. How spoiled are audiophiles these days :-)

        I have a few questions.
        Does anyone here really hear changes in fuses.
        Fuse directions.
        Tried a larger gauge fuse size

        also IEC inlets by law needs a noise suppressor inside the keep noise being made by our products from going back into the power lines. Using one without it some feel improves things.

          Yes and I've heard fuses make or break a component. In this case, the fuse made the preamplifier sound very non-linear. Then popped in one of the HFT fuses and all was better.


          Yes on fuse direction. In fact, the new HFT fuses are supposed to be non-directional but I still find them directional. The little quantum dots also improve the sound of the HFT fuses. FWIW....

            +1 on everything. I have even changed the fuse in the PSU of my Turntable motor to good effect.

              Fuse directions.
              Absolutely. Tried many versions of Hi-Fi Tuning, Furutech and SR and all of them were better than stock fuses. The direction is sometimes even more important than the fuse itself. SR 20 with the right orientation sounded considerably better than the RED with the wrong one. Zanden delivers fuses for their products with marked orientation.

                Fuses directional? While that might be possible in a dc circuit like the power suppy, it simply makes no sense in the mains fuse which is AC current.

                  Yup, I stand corrected. If the AC mains fuse acts like a rectifier at power frequency, then direction may affect sound. But I will say that a fuse that acts like a rectifier at power frequency is a very bad ac mains fuse.

                    What ever the technical reasons behind it , the question is, is it relevant in my system. I find for the majority of the people who are willing to sit down and give it a listen, there is a difference that is clear. IMHO this should be motivation enough to give it a go.

                    Not sure if Synergistic research still offer a 30 day money back guarantee>? In which case there would not even be any finacial risk involved in such a endeavor.

                        I know. I looked for something like that and couldn't find any. Funny thing is I remember something like the above picture but can't find any. I swear Acme Audio used to make one like that.
