    It is not in the audio chain.
    neither is the fuse in a mains plug. There is no credible technical explanation for how these fuses can make a difference when used anywhere, so there's not much point asking that question.

    Surely, if these 'super-fuses do enhance the SQ, by implication the lesser ordinary ones must introduce some form of signal modulation, which I find hard to believe.

    There is a posh fuse for sale for just 25 bones, so I initially thought it might be worth a punt. But... it is only rated 1A. I've no idea where something like that could go in my kit. Everything seems to be 3A and above (and as some have said may be pointless), and God knows what they would be inside the components. Can't find any info.

    If I didn't know better I'd swear the manufacturers are trying to dissuade users from dicking around with their products. And these things come in a variety of fuse ratings AND sizes. Minefield.

    I was curious, but not so curious that I'd risk throwing away the price of a shiny new piece of vinyl. And probably break my stereo.

    Forget the past, it's gone. And don't worry about the future, it doesn't exist. There is only NOW.

    Silly me, I thought the discussion was about 13amp fuses that go in UK plugs……. So can’t see how that would upset, damage a vinyl record.

    Turntable power supply:

    Less electrical noise on incoming AC to power supply (which reducing the 'choke point' impact by improving the fuse would do) would benefit the TT motor in terms of speed regulation, as well as less noise injected into the playback chain generally.

    Howzat?

    Thinking of the fuse as part of the electrical system of the equipment:
    Who all here uses aftermarket power cables to power their gear?

    Assuming it made an improvement in your system?
    Why do you think that is?

    Ive said this a lot in the past,
    Less noise on the AC feeding your kit improves the sound.

    Its all about reducing the impact of electrical noise feeding your system.
    Many things can affect this, incoming AC supply, cables and yes, fuses.

    Its being open to acthally TRYING things in your system, that you can decide for yourself if you can improve your system.
    Thats part of the fun of the hobby for me, and who doesnt want their favourite music to sound better?


    Thats my take.

    I don't think the discussion was about 13A fuses, anyway I don't think any of my kit uses ones rated at 13A. Maybe my kettle does

    And I never suggested that I could damage a record by changing fuses - rather that my £25 that fuse would cost could buy me a new album.

    I do, but I make them myself rather than pay the absurd prices charged.

    Fuses don't act as "choke points" any more than say switch contacts or the contact points between a plug and socket. All they do is increase the line resistance slightly (which in the case of a BS1362 13A fuse, will be no more than 6 mOhm).

    Like I said if it fixes a problem then that's different, but on a system with no problems it's very hard, I think impossible, to accurately verify the effect of tweaks like these fuses.

    All said and done if someone is still thinking there is a possibility of a better sound go ahead and try them and report your subjective findings here.
    Well it works for me - and in most cases the 'improvement' I heard was imaginary. Only on a very few occasions has changing an item (a power amplifier) lead to an immediate improvement, which was lost upon returning to the status quo.

    In the '70s some American high power amplifiers had fuses fitted in their speaker outputs for protection against short circuits.
