    I believe fuses should be used only as a prevention against fires - they won't blow fast enough to save transistors. If you accept that they're there as a safety feature to to prevent fires and do not behave like an ordinary piece of wire, it should be possible to mitigate the effects of any odd/non-audiophile behaviour at the design stage.
    I suppose I'm saying that any audible effects will depend on the way the amp or whatever has been designed in the first place.

    I will of course say that a fuse can have no effect and this is a complete waste of time and money... and no I don't "trust anyone's ears" on this... If 1000 people all said it was a huge upgrade I'd still say your all imagining it!

    The only time a fuse can have an effect on sound is if it is between the output of an amp and a speaker, where they should not be used but sometimes are.

    Impossible trumps opinion every time.... No matter whose opinion or how many agree with it... The world remains round even if you're in a room full of hundreds of people yelling at you that it is obviously flat!!

    Does no one think it rather suspicious that all "incredible" (literally) after market tweaks come in the form of something that can be simply unplugged/disconnected and then be replaced by the new one by non technical people and without any soldering? Non of the hundreds of other parts in a piece of kit which are soldered in just happen to be the magic tweak?

    Now whilst it should be bloody obvious why not anyway, I could write a long technical piece here explaining precisely how and why it's impossible for a fuse to have any effect... but I'll save myself the bother as believers in foo are like any religious believer, in that no amount of evidence to the contrary is going to shake their "faith".

    Hey Jez,

    No faith-based purchase or kool-aid drank here, just what my ears tell me.
    Nothing to sell here, no dog in the race...just passing on direct experience of listening in my system to folks.

    I find it a bit of a puzzler as well, know the theory so its a surprise the level of improvement.
    Genuinely interested in what you think of this from an EE's point of view:

    Could the use of graphene as the fuse element rather than normal fuse metal have any effect electrically?

    Doesn't necessarily follow that its audible of course, but could that affect how the fuse passes current through it before it gets converted to audio signal?
    We know how important a good clean power supply is to reproduction, could this be the first part of the chain and its removing a choke point before current flows into the equipment?

    Happy to look at any evidence you have to say that the fuse has no direct effect on any electrical property of current flowing through it and entering the equipment.
    And what does the fuse do when its between amp and speaker, how does this have an effect?

    Ta.

    It's good to be aware of the parameters under which a device performs. It's not terribly useful to be scared off by them..

    Jez, that's pretty much what I'm saying - I just don't dare put it as bluntly as that

    I've known plenty of fuse holders to be a loose fit and/or have tarnished contacts. Simply pulling out one fuse and replacing it with another could clean up the contacts. Just a thought.

    Me too, its definitely noticeable.
    That in fact was what got me interested in at least trying one of these SR Fuses. Last week I cleaned up all the stock fuses and holders in my system and noticed the improvement.

    So comparing to that, I put the SR fuse in and genuinely taken back with the level of improvement.
    It's not subtle.

    What might have been the cause of that, isn't the BPS regulated for inrush current?
    I think it was my fault, it should have given the BPS time to at least come to life before i pulled a load of current from it.
    I've got no inrush protection on my BPS I try and run it as streamlined as I can. The ones I have sold on have protection on the secondaries and most have inrush protection.

    Would you trust your own ears, then? I'm as sceptical as you are but if Gaz is saying there is a big difference then I'm inclined to think something is going on. I'd be happier if I knew for certain that he has not changed anything else that may be a more rational reason for an improvement.

    The fact is that if the fuse alone affects sound quality all bets are off about pretty much everything and that is just a little bit scary.

    I had some fuses blow on my power amp and replaced them with like for like fuses a while back and I heard a significant Increase in dynamics after. This got me investigating fuses myself as I had personal experience of something happening.

    However my journey was a bit short as I discovered that after trying a few specialist fuses the cheap Maplin ones sounded better. The Hi-Fi tuning fuse actually made my system sound flatter! So although I totally agree they can make a difference it maybe not always for the better!
