Hi-Fi tuned Fuse

In my extremely limited understanding, unless your current fuse is restricting the maximum current flow to the amp then it can't make a difference. I can't see how it can add noise but I'm not a specialist in the field; is anyone?

It is 13 amp fuse which is the wrong rating for most domestic hifi amplifiers. (13amp is for electric kettles and other kilowatt+ items.)
For safety reasons 3amp (or 5amp) fuses should be used unless the hifi has some 'monster' amplifier attached!

certainly dont want to blow any

At 13A you aren't likely to. Your gear is going to go up in smoke before one of these goes unless you have 3A or 5A on your components.

Russ Andrews has said for years how circuit breakers are much better than fuses, as they allow the FULL mains supply to run down the line and only trip when a short occurs.(and they react much faster to them as well)
From personal experience over many years myself I do agree with him.
The speed, depth/body and tempo of music benefits from a fuse less system. Due mainly I think to the reservoir caps being able to carry a fuller load along with faster recharge times.
The cost of fuses is cheap relative to the cost of circuit breakers.

I can't see how any fuse running within it's rated current capability could have any effect (detrimental or otherwise) on the sound.
At the end of the day, it's a (very, very short) piece of wire, designed to snap when it's rated current is exceeded.
To my mind, the most crucial part, is the contact area between the fuse and fuse holder, and unless both items are gold / gold plated, I fail to see the point of gold plated contacts. I believe that it would in fact be better to have a fuse with brass end caps, unless you happen to be using a plug with a gold plated fuse holder..
And all the plating - "gold over silver end caps" and "pure silver wiring"..... There surely has to be some compromise in electrical conductivity with all this plating...
Also, the seller of this fuse states "ceramic casing, rather than glass, for better resonance characteristics" - well don't all UK mains fuses have ceramic bodies? And as far as I know - ceramic bodies are used because of their superior non flame properties - glass fuses have a tendency to shatter under circumstances of extreme failure. And resonance? In such a small device, which is passing 50hz mains? That did make me laugh...
My suggestion? Stick with the 20p fuse you can buy in the shop, buff up the end caps with a bit of 400 grit sandpaper, clean the fuse holder in the plug using the same method, and save yourself £25 !!
Pass me another can of snake oil please!!!

P.S. and as another poster pointed out: 13A is overated for most Hi-Fi kit.
