    Yep +1

    I gave a firm refusal to that request.

    Interestingly, on another hifi forum the rule used to be (and possibly still is) a zero tolerance permanent ban for such postings.

    It's only hifi - that extra 5% sound quality is not worth you and your family and possibly neighbours and fire fighters dying for.

    +1 (again)

    At the time I encouraged that it was 'ok' to replace fuse with copper bar as I wasn't soldering anything in, what I was doing was easily reversable.
    My choice though at the end of the day.
    In hindsight though...


    PUBLIC SERVICE / SAFETY BROADCAST
    Some sagely wisdom from someone I trusted with electrical advice on my own kit..
    What makes it worse, was asked to run my kit without a fuse with no concern for my kit blowing up, but as a "test" to find out re: the SR fuse if I was a liar, shilling for God knows who..or deluded.

    Speaking about my specifc piece of kit:
    Even if there is no protection, no CU trip, no fuse, then the coil winding of the transformer becomes the fuse and it would open circuit very quickly, but would get very hot in the process but not enough to flame or damage anything just some smell and maybe a little smoke looking at the transformer spec. It would have to be replaced anyway so no difference.

    Sure,
    no bother I'll do that, dont mind a little smoke here and there!
    And I'll buy my used car somewhere else thanks.

    In Spain there are NO fuses in plugs and all my gear is wired direct to separate spurs. Most appliances here aren't even earthed - though all of mine are.

    Not really stupid, just a calculated risk. Ok, more of an estimated risk, but I'd estimate the risk at 1000 - 1. If a piece of kit has been working fine for years, there's no reason for it to suddenly develop a fault in the five minutes after a fuse swap.
    Don't get me wrong, I'm not advocating that it's safe to leave the fuse bypassed long term, but it's a low risk experiment for five minutes.

    Indeed, and whilst the warnings are 100% justified (and welcome), one wonders, statistically, how many fires every year are caused by hi-fis, as opposed to, say, Christmas tree lights, washing machines, chip pans, cigarettes, etc...?

    I suppose that everyone's risk assessment is calculated differently, and of course if in doubt, play it safe

    Felt it was an acceptable risk at the time, but in hindsight not so much.

    Risk would have been a lot less than that tbh. Long term, would be asking for trouble. There has to be something give in the event of a short for instance or you will get flames eventually as things heat up . Its probably true that our electrical codes are somewhat over protective, but there are good reasons why they are. I prefer the safety fuse to a potential of some sightly better sounding stereo. If however its done as a short term observed test by someone who knows what he is doing and has taken precautions then the risks would be acceptable.
    I understand why folk do it though as like many things in life, forbidden fruits taste best

    Standard lack of concern from the man in question, who's own equipment contains no fuses or safety protection circuitry whatsoever, the design of which he ridiculously tries to justify. The whole "shilling" thing is a joke, and part of the sufferer's deluded mental condition. He has an inexplicable mania for "shilling"!

    There is/was no shilling or "scam" on your part... You were simply tempted to try an 'audiophile fuse', entirely of your own accord, and when you did, and found it improved the performance of your hi-fi system, proceeded to tell others, which is normal and perfectly natural practice on an enthusiast-orientated audio forum, such as this, in case they might be interested in doing the same.

    You were then subjected to a tirade of abuse, and treated disgracefully by the forum owner and his arse-lickers, simply because part of what you were reporting didn't fit with their world view or 'belief system', and most importantly, because they consider ridiculing people that they don't like or agree with as 'entertainment'. How sad. But then when you don't have much of a life, I guess you have to get your 'kicks' when you can....

    The proof that there is/was no "shilling" will become patently obvious when discussion of this particular tweak runs its course and dies a natural death, which will happen sooner rather than later... As indeed is the case with 95% of such tweaks, with probably no more than half a dozen people in total having been tempted to buy one of the fuses in question [hardly the basis of successful shill or scam], leaving the accuser of such looking once again like a deluded and demented tit!
