It's all bulldust. Same with silver replacement cables between the power socket and the power supply. Do not feed these idiots.
I have no opinion of the guy, I haven't met him.
Regarding fuses, yes they can make difference, eg plain glass fuses or ceramic sand filled fuses sound different.
No need to buy so called Audiophile fuses, RS Components, Farnell etc have range of fuses suitable for economical experimentation.

That poor guy in the video!
Something must have hit him on the head, or maybe he suffers from some illness.... who knows.
Actually promoting a silly boutique fuse?...... which anyone (sane) knows that it doesn't mean a crap of difference to anything on this planet.
Some people need to get a life.

It depends on where the fuse is used. I've seen glass fuses in the signal path on Magnepan speakers and bridging those makes a huge difference in sound.
But fuses in the power section? Nah, I don't believe it. If you look at PSU desgins, a lot of them use chokes to filter out spikes and noise and arguably a choke is far worse in reacting to changes in amperage than any fuse out there. So replacing the PSU fuse doesn't make much sense to me.
Been living on Mars? Or just trolling? Either way the entire troll community will gather shortly here in defense of science 🙄
@analog i originally thought snake oil, but after sleeping on it i realised that i had not tested it for my self and so shouldnt have used the "S" word.
ps i live in a cave, they dont let me out much, but seriously i'm quite new to diy-hifi, and have not seen a 35 quid fuse before.

Yes fuses are nonlinear resistance and this is quoted as reason in the likes of Magnepan etc.
IME it's subtle and some fuses just cause gear to sound different, and I find ceramic sand filled fuses preferable, there are different end cap platings and fuse wire compositions including silver, even different sands if you look closely at the ranges of M205 and 3AG fuses available at RS Farnell Mouser etc.
It's just something to be aware of and can make that final difference in a system, a pack of known good fuses is not expensive, try it you might find a useful difference.

An AC power line in the US is not supposed to drop more than 5% from no load to full load, so with a standard 200 amp feed what does that mean the equivalent power line resistance must be all the way from the power plant through the wires and transformers to your AC panel?
From the input to the panel to the outlet another 5% is allowed. So how much additional resistance can that be for even a 15 amp outlet? 15 amps is the lowest rated outlet!
From the outlet through the AC connectors on both ends with a 6' 18 gauge cord how much additional resistance could there be?
What is the range of a fuse's resistance from minimum current to peak current?
What is the power supply rejection ratio at very low frequencies of the gear being used?
What effect will the variable fuse resistance have on the power amplifier rail voltage?
What percent of rail voltage drop would cause a 1 dB change in power level? 1 dB usually being considered the threshold of perceptable change.

If you have a positive experience with changing fuses then stick with it. To me it sounds a bit like the theory that the polarity of the mains connector is also important. You know, where the phase of the outlet has to be connected to the prong of the connector that goes to the fuse and then the transformer. Or the wooden blocks with the mu metal in them that had to be placed over the transformer so they would eliminate the magnetic of field the transformer. If there is any difference is it so subtle that most people will only hear it because they want to hear it, so you're almost in the psychosomatic/placebo field.
But that's just how I see/hear it and opinions/experience will differ.

Transformer winding parasitic capacitance to chassis is not symmetrical, mains polarity can be important because of this.
Oh you mean the VPI Brick yes they altered amplifier sound no question.
I don't do snake oil. But audio frequency modulation of resistance of fuses has been shown and known for over 50 years.
Don't nay-say everything you have not studied.

i had absolutely no idea that something as small and simple as a fuse could have the effects that some have described.
But you have to understand, any "effects" that a thin fuse wire contributes is minimal, basically inconsequential. - the general population doesn't give it any thought.
Only those who insist on nit-picking about the so-called "deterimental" issues and concerning themselves with the trivialities bring about discussions like this.
It's like overthinking a single grain of sand on the beach and mulling over how it may affect the tides when they come in.
Come on now, don't let stuff like this make you an insane nutcase.
@wise
TBH wise right now i have lots of little projects that are keeping me busy but, in the future when i have time i'm going to give "special fuses" a try just so i can find out for my self. i originally called snake oil, which was short sighted because without trying it my self i couldnt know for sure.
