    I trawled through the first 30 pages of this thread this afternoon with some dismay because I thought I had put this to bed some time ago as mythical in the case of fuses.

    Alas no, some hear differences, and it is unscientific to be dismissive of them, they involve perceptions as much as other scientifically based things.

    There is no doubt that fuses do, as with other crude connections, oxidize, and they escape our attention for long periods.

    In the 70s I used Belling-Lee coax plugs and sockets for connection using a 'Y' cable between my Quad 33 pre and Nelson Jones 10+10 class 'A' power amp. This illustrated to all visiting that polishing the plugs and sockets improved the sound considerably into Tannoy Gold Lancasters, and engineers laughed at this as 'silly engineering'.

    For both my Hi-Fi and my studio I have home made distribution boards, seven on the Hi-Fi one and eleven on the studio one.
    In the former I have used the 5A Duraplug type because it is much easier to get a good contact between a round pin hole, than a square pin and a square hole, in which a fraction of a degree of error from square results in an infinitely small contact area.

    I have also doubled the flex, soldered it, and cut half round stainless steel tubes which go under the screws to prevent them cutting the 'blobbed' flex strands, and also increased the size of the screws from 6BA to 4BA.

    Although, what 'logic' has to do with this thread, I'm not sure
    But, hey, 400 posts ... impressive!

    Good post.

    In my own experience, given that all power eventually becomes what you hear and actually goes through the fuse, I see it as an integral part of the power supply.
    Its a potential 'choke point' and I think this may be where any improvements may come from.

    Agree with you on Deoxit and Pro Gold, its great stuff.

    So normal electricity comes out of the wall, goes through the fuse, and gets all high quality 'quantumized' and this has such an effect on the electrons that it lasts through the rest of the system all the way to the drive units...

    Seems like we need only install one biggun at the power station then we can all enjoy it.

    As well as sounding like total bullshit.

    Ill be writing to the importer and asking for proof of Eu/BS compliance and passing it on accordingly.

    Yup.

    American kit can sound pretty good, and doesn't meet Eu/BS compliance?
    French, Dutch, Japanese, Swahili (and now I come to think on it Punjabian Urdu) kit can all sound pretty decent too?

    As with my original post on SR Black fuses Si, it's what I heard in my system with my ears.

    I don't doubt what you think you heard. I do doubt their safety as fuses.

    My instinct sq225917, is to be as dismissive as you are about the fuse itself, but we need level matching within 0.1dB, and random D.B. testing to validate differences.

    As for safety, a fuse cannot be that difficult to design, and as a long as the wire has the right melting current and time to do so, surely it will protect the equipment. The surrounding sleeve must be easy to make comply surely?

    Apart from cleaning contacts, I cannot see any 'magic' being conferred onto the sound, but our perceptions cannot be dismissed without investigation.

    Some folk think that electricity flows one way into a system and therefore the fuse influence is small,but Hifi components sit between live and neutral and AC power oscillates between 50-60hz. Therefore as well as cables being influential so are fuses in this context as they sit between a complex network of cables,wires and connectors. These all have an effect on the components power supply.

    Another misconception is that the component sits at the end of an electrical supply but the component sees itself at the beginning and end!

    Fuses are just there as protection.

    I'm drowning in the non sequiturs of post 418.
