snake oil?

Not fuses, but this appeared in a site while I was looking for some inexpensive full range drivers.
Bear in mind, your speakers arent just sitting there until they are sitting on these- made of rare fir.

Sleepy. Had to reread it- I thought your post read as invertebrate cable lifters.
Sleep deprived here too. I read it as invertebrate too. I then had to go look up 'inveterate'. Learned a new word today. Thanks. 🙂

The Cardas yellow fir BS is pretty funny actually. Fir turns hard as a rock over time. I know. My house is made of old growth fir. Built in 1912. You have to pre-drill if you want to pound a nail into it. I've heard some call it ironwood. Does this mean you'll have to replace your Cardas yellow fir blocks periodically for maximum sonic effect? 🙂

Better to talk about the topic itself rather than talking about the people talking.

AS to jumping a fuse making a difference. I have novice techs check a fuse and think that is that. Doesn't occur to them the fuse holder is part of the circuit. ANyone encountering a fuse clip that suffered from heating and went resistive can appreciate that.
A fuse does have a small internal resistance, needed for the fuse to operate at all. Inserting that into a line where small impedance changes affect circuit performance could result in some small audible artifact. As an example the effect might be noticeable in a speaker fuse setting. In a power supply, operating op amp circuits with high power supply rejection ratio (PSRR), not so much. Any fuse-caused effects would be detectable only using instrumentation that picks up on signals way to small for human ear to hear.
