Fuses
I’ve read of views on whether amp fuses impart any sound quality or coloring. I had a recent experience that has made me re-think my views (fuses do not affect sound) and wondered if others had a similar experience.
I have a Line Magnetic integrated amp. After heavy regular use for over 5 years, one day it just wouldn’t power up. After checking the power supply, I assumed it must be a blown fuse. I recalled that Line Magnetic sent with the amp two replacement fuses of the same type/quality that was pre-installed. I dug out one of them from storage, replaced the fuse and the amp powered up normally.
What surprised and delighted me was the change in sound with the replacement fuse. Fuller bass, more detail and more warmth. I have rolled the tubes several times in the amp, and am attuned to the subtle changes that can make. Popping in a fresh fuse seems to have had a similar affect. And these appear to be cheap fuses, available for a few dollars at most. I don’t think I understand any of this.

Hi Fi Tuning Supreme fuses apparently use a silver, copper, gold mix solder, but a solid copper melt wire. They have gold end caps, ceramic body, and are cryogenically treated. I have not heard of any fuses that use the gold-plated Neotech wire you asked about (or the silver-gold Mundorf wire) as melt wire inside of the fuse...unless SR is using something special. I cannot find a description of the melt wire used in the SR fuses, although they list all the other pieces and parts....i.e., Orange: Ceramic Body, Silica Filled, Brass Nickel Plated Contacts,1,000,000 volt multi-stage, high-frequency conditioning process, 2nd Stage Rev. 2.0 Molecular realignment process, Directional UEF Compound first developed for Galileo SX PowerCellGrapheneI have considered filling a conventional fuse with beeswax (just for fun and curiosity) by drilling a small hole and using a syringe to inject warm beeswax, but have not considered making fuses with filament wire of my choice. I am curious how you achieve the correct break values when using your own wire, do you test them? After trying a variety of HiFi Tuning and SR fuses, and not hearing anything that makes me want to spend the money, my go-to has been to use mostly ceramic-body fuses with, Teflon tape wrapped around the body for damping, contact treatment on the ends, and small orthodontic rubber bands to provide tension on board-mounted fuse holders. For $20, I will consider ordering the ACME fuses to replace older fuses, as I have used their silver-plated outlets. |
