The new Synergistic Research BLUE fuses ....
It is just his one sided determination to derail this thread with bunkum No sorry, it’s giving the technically weak a chance to compare a side (dominated by the awesome foursome) that’s not at all technical and considered to be "snake oil". To be compared to a side that has only presented technical merit, that a >$100 boutique AC mains fuse is no better than a quality $2 fuse. If you have a tired original fuse because of too many switch on surges, all you have to do is change it for the same quality $2 one.

At high temperatures, oxidation may happen, which weakens the wire mechanically, and may be electrically, too. Switching on/off a load means the wire is bent each time. Another way to look at this: a fuse is like a light bulb, the old type with a hot filament. Although very hot, it still takes some amazing 1000 hr to melt. And even at under-voltage, burning lower, it will not light ’forever’ and will get dimmer as resistance builds then blows, always at switch-on, that's why the new globe always seems/is brighter, even though the same wattage.

What about the fuses I’ve linked to that use powder to keep the temp down so it doesn’t age the same as the fuses you use? They’re readily available, cost only $4 apiece, and perform better. They’ve been around for many years and the technically proficient know of them. It’s the type of fuse that aftermarket makes based their audio fuses on with an ear and eye towards bettering the sound, and admittedly, making a profit on. You don’t need to spend what SR changes unless you like the results you get as there are well made ones for a lot less. But to each, their own. Get a new hobby horse, George. All the best, Nonoise |
They’re readily available, cost only $4 apieceHey, put your ! cap on, I’ve got nothing bad to say about quality fuses for a couple of dollars, it’s all about the >$100 boutique ones, that bleed the gullible of their hard earned cash. As I said before you wouldn’t get notables like the industries design "gods" like Nelson Pass, John Curl, Dan D’Agostino ect ect ect talking about fuses the way they are frothed about here. And if those fuse froth’ers went to the sites like DIYAudio.com where they (the gods) hang out, and started talking about fuses they way they do here, they would get toyed around with then spat out severely once they tried of them. As for sand/quartz filled fuses. It doesn’t make them sound any better. It also absorbs the energy when they blow and stops a big mess by most of the time not shattering into pieces.. " Current limiting fuses contain a granular filler, usually high purity quartz sand of a defined grain size and packaging density. The specific grain size distribution provides room to expand for the vapours and gases produced by the arc and offers a large surface for efficient cooling. The filler does melt under the influence of high arc temperatures, absorbing an enormous amount of energy and extinguishing the arc well before current zero. Fused quartz and metal form a non-conductive fulgurite body that prevents re-striking of the arc." Cheers George |
