Thanks for that, the original source from the actual book is :
13.11 Fuse, Relay, and Connector Distortion
Many amplifiers employ fuses or relays in the output signal path.................
Once again it is all about putting a fuse in series with the loudspeaker, something no one in their right mind would consider and not at all relevant here.
It seems both these quotes have been taken out of context and cut to hide their real meaning, this is always a potential problem when surfing the net. Cut and pasting from another forum, or anywhere, does not make it correct.
Remember my comment on the Bristol Show and my offer to measure (with conditions) here a few days ago. I have nothing to gain or loose over this, but a curiosity with no burning desire or agenda.

Once again it is all about putting a fuse in series with the loudspeaker Acknowledged but it's still pertinent to putting fuses in the mains supply and DC power rails, all of which are modulated by the signal and amplification demands. The fuse is still going to behave in a non-linear fashion in such applications. |

But then it's inside the feedback loop. What I'm saying is, that the scientific evidence so far produced here, is largely incorrect. I did offer to measure the "A measured and calculated 8%" and I believe that is where I came in ?

The DC fuses are possibly in the feedback loop (but may be on the raw DC side directly after the bridge rectifiers), but will still have a small effect according to the NFB gain. Use your ears, it is what they are for! |

1. The mains fuse is not inside the feedback loop. Actually if you analise it, it is inside the feedback loop. Yes I can listen, I have never doubted that. My question is, and always has been "A measured and calculated 8%" and I believe that is where I came in ? |

Measurements seem to be important to some people, but to me it is and will only ever been how it sounds that influences me.
I remember a discussion I had with a manufacturer at a Hifi show in Brighton a few years ago, where he was claiming that their tiny speakers were producing really deep bass, and were showing me the measurements on a chart. I explained that they may well have done, but they didn't sound like it, they just sounded thin and bass light. He was not at all happy.
These fuses are likely exactly the same. Whether they measure well or not would be entirely irrelevant to me.

I'm waiting for Martin to "blow a fuse!" LOL! Not going to happen, Steve. I'm quite happy with intelligent debate. However, it is how the component/accessory/tweak sounds that is of utmost interest to me, and I'm already sold on SR Red and Black fuses. To a lesser degree, as reviewed some time ago, I also think the AMR Gold fuses are good and represent great value for money. |

Lol, So your cunning plan would involve me dismantling my music system for god knows how long, trusting £60000 of amplification to the tender care of a shipping company to be delivered to an individual not personally known to me ? Let me think about that one  All Instead of simply acquiring an SR Blue fuse ( at less cost than available to most ) and conducting your own experimentation ! |

Let me think about that one  OK, meet me at the offices of HiFi World then ? You stay and watch ? I can't replicate your 8% claim without the equipment in question. |

It is a shame that we are no closer to getting any measurements though ... Nobody cares about moon's 8% calculation, including moon himself! Any 'independent' testing by those qualified to do so will do! |

£60000 worth of amplification and a £130 fuse makes a difference... I can't get my head round whether that should be applauded or not....

Now even I am getting seriously bored with this thread.
Ergo:-
If you have tried the fuse and you like what it does, then keep it, buy more if you wish.
If you have tried the fuse and do not like, return for a refund.
Making claims that you may find difficult to prove without said equipment/environment/ situation being identical then it is very similar to pissing in the wind around 5mm for a 50Kv electric fence on a storm force day in wet.
I can appreciate both sides of the argument no question, and I firmly believe in fuses making a difference, however my life does not involve posting countless points and counter points on a bloody fuse more than enough work to do in a day!
Really we have dedicated less time debating the various deadly afflictions of the human race, they're causes and potential cures compared to either Valves V's solid state or fornicating fuse construction techniques, material and potential benefits against blinkered individuals with they own agenda's on various subjects!

Why would I feel the need for you to validate anything that I have conducted and written about here Dave ? I am neither the manufacturer or retailer of this product, nor Mr Atkinson. My query remains, why not acquire an SR Blue and conduct an instrument level suite of tests yourself ? At the same time you might as well listen to some music and pen your considerations here, I am sure that there are many here interested in your results from both. You seem to have missed this previous post...Oh dear I fear that an agenda is starting to appear from behind your kindly offer of assistance. |
