Speaker fuses 2019-07-10 18:16:13 I've done a web search, and other than the usual "manufacturers flogging their wares" I haven't seen any scientific tests on the contribution of speaker fuses to distortion (audible or not). Clearly the resistance changes as the fuse wire heats up, but the big companies like Littelfuse don't publish that data openly. I did stumble across a graph which showed, without attribution, measured distortion in the range of 0.01% to 0.1% for a 2A FB fuse operating at rated current. If true, that would pretty clearly be negligible.Is anyone aware of proper tests (measurements or listening) being run on speaker fuses, or is it considered not worth the effort? Has anyone characterized the linearity of a standard fast-blow fuse vs. current and published the data? I will not run my main system without fuses, but I would like to be able to point others to a good justification that it won't harm their listening experience.
