Then you could lock this boring thread which was started for one reason only

We try not to lock threads, Andr'e. A specialist fuse represents one of the more affordable upgrades for a high end system that some of us have tried, so it's fair game.

A specialist fuse represents one of the more affordable upgrades for a high end system It sounds daft but it's true. I've put one of these £90 fuses in my system so far and it is like a major component upgrade. My 2nd one has arrived, but haven't gotten around to installing it yet - I'm still luxuriating in the benefits from the first one. |

From memory there is nothing on the fuse.
I'll have a look on the box

Yes, tempting! -- but I like to spread system upgrades over time. More fun to be had that way. |

I will be taking a fuse home for Nick to collect tonight when he drops me some power supplies off. He will test and measure one.  Any news on the measurement and testing? |

And if you bung one in the return (neutral) line - you'll be luxuriating twice as much, no doubt. |

Well, had a session down at vinylspinners today. He put one in the coffee machine. Best I've ever tasted!
More seriously, many years ago I can remember experiments being done on WAD valve amp kits. These came as standard with 1.6 amp fuses. Once all voltages had been checked as correct and the amps had been found stable after a good period of running, some of us uprated our fuses. I went up to 5 amp in my KaT88 and there was a noticable improvement, mainly to the weight and authority within the music and it wasn't just me who noticed it. I suspect these boutique fuses are achieving the same sort of thing. It would just be good to know how exactly they achieve it.

I checked one of the SR Blacks. No safety markings. I then looked at an AMR Gold and it has the kite mark.
Make of that what you will. Doesn't change my findings that the AMR Gold is good, the SR Red/Black is better.

Fuses aside, Just something to think about, Things need constant service to keep up to scratch. Say you leave all your connectors, for quite some time, they will start to oxidise, You wont notice any sound deterioration short term, same with an Audio cartridge, Your brain will just get accustomed any difference over time..you suddenly go polish something within the chain you will hear immediately a fractional difference, It is not an upgrade. This is all you are hearing something new squeeky clean. Its then oddly branded an upgrade..
For example, i recently bought an old amp, Gave it a go, sounded ok but the connectors were tarnished, after polishing them i re connected the amp to find it sounded a lot better, all because of some dirty sockets

This is why I recommend Deoxit spray. It cleans and preserves. Use it on every connection - mains, signal, speaker. Use it on fuseholders, too. It's great stuff and keeps your system sounding at its best.

How would you describe the 'change' with the Black ? |

It creates more space in the soundstage, a better sensation of the extremities, notes and voices hang in the air with sharper focus, the noise floor drops. All these things happen in my system but there's no guarantee that it will happen in anyone else's.
Before you go to the expense of a better fuse for the Sansui, make sure that its power is going straight to the wall and not via another distributor. Use a decent cable and clean the pins both ends. If its possible, exchange the wall socket for an unswitched variety. Then try the fuse (after adapting to the current sound). Let us know what you think.

Doesn't change my findings that the AMR Gold is good, the SR Red/Black is better. So of the two, one of them has had batch testing by an external testing and certification house. The AMR fuse can properly be referred to as a fuse, and its rating and designation are accurate. |

It's great stuff and keeps your system sounding at its best I've never used Deoxit but I did notice this when looking at my preamp manual yesterday - < Special contact cleaners and contact enhancers should not be used as they tend to deposit a film, which is very difficult to remove and may degrade the sound.> Obviously you're very happy with what Deoxit does, but was just interested to know if it leaves such a film behind? |

And the other might blow if a fault condition occurs, if we're lucky? Of course you'd have to pray that the fault condition never occurs, because a replacement like for like is so damned expensive. |
