I fired up the system today, started playing some music and had a thought: I had no recollection of replacing the fuse in the IEC socket at the back of my Belles power amp. I remember doing the cable plug, but not the other end. I pulled the slider out and it was indeed a standard 4A glass fuse (the rear panel says it should be 3.15A for 240V). How had I missed that? I checked in my bag of bits and found a 20mm SR Red 3.15A - perfect! I put that in, checking alignment as I standardise on reading SR left (input) to right (output). It didn't cost me a thing as that fuse had come out of the P10 when I put an SR Blue in there. I carried on playing what I had lined up - Brandi Carlile - and there was a small but noticeable improvement to drum beats and openness in her voice, which is particularly expressive. For the rest of the evening I played more Brandi and some Tanita Tikaram and my current fave Juliette Commagere. I just love breathy female voice. So the answer to your question pre65 is that another fuse gives a small improvement despite being the second one in series (no, I hadn't intended to do this experiment)! |

You're going to hate me for this, Martin, but standardizing which way round your fuses are inserted will do you no good at all. According to the manufacturer's website, when I read it, each fuse should be tried both ways round to see which way gives the best performance. I remember taking the p*ss out of the fact that although they were directional the manufacturer didn't know which direction they were directional in.
Taking the law of averages into account 50% of your fuses could be the wrong way round and by reversing those you would get even better performance than you're hearing at the moment. At that price, I'd want to get them the right way round I think.

It's been my finding with directional cables and fuses that they eventually 'acquire' directionality as you use them. So if you get it wrong, they will gradually correct themselves. This is supported by Russ Andrews among others.
I did, in fact, try the Red both ways and found that it went the right way as I had used it previously in the P10 in the same direction.

Paul McGowan PS Audio says much the same.
More and less weird in equal measure !

What would measuring a fuse prove?

What would measuring a fuse prove? That they give a "A measured and calculated 8%" increase in gain/power ? That was my "only" reason for measurement, and again; see my previous comment on Bristol ? Pop a couple in the post ? |

Buy the best cables you can find for your budget. They will gain directionality or not (the mechanism by which cables gain directionality does not seem to be understood). Even if not marked with a direction, they may sound better one way against the other after time.

Today I noticed extra flesh on the midrange of my sound. Nothing has changed in my system for a while so I’m wondering if they done their last bit of opening up. There’s more presence and immediacy to the whole frequency range (don’t read forwardness, this is a positive change).

There’s more presence and immediacy to the whole frequency range (don’t read forwardness, this is a positive change). The quality of aural delusion is that what is heard is the real thing. The undeluded also know the sound of the real thing. Both ultimately will be happy with what they hear. The difference is it just costs a bit more to enjoy your music if you are delusionally afflicted. Other than that, there is no difference. |

Accusing another member of being 'delusionally afflicted' is insulting. I'm sure we made it clear that if you haven't tried one, your opinion is worthless.

There’s more presence and immediacy to the whole frequency range (don’t read forwardness, this is a positive change). As I listen to the same CDs for a while I find much the same. Knowing the albums well I often stop and realise there has been a step up in sound quality that has crept up on me. |

Agreed. I'm fairly sure the new Blues are settled in but the Red that I put in the power amp has only just got there.

There is something going on that is currently (!) not being measured with instruments.
The ears and brain confirm improvements.
Only since I've been upgrading have I had these moments of delight where I hear more into the music.
Going back to the same track sometimes to confirm and luxuriate in the sound

Accusing another member of being 'delusionally afflicted' is insulting. I'm sure we made it clear that if you haven't tried one, your opinion is worthless. I remember the AoS crowd being totally convinced that a none standard mains cable made very noticeable difference to their system. Following the you must try one to have a valid opinion i tried one. I still have it but I just could not experience what many others said they could. My modestly educated thought processes did suggest to me that I would be unlikely to hear owt. On that basis I tend to avoid having to try things others speak about which my mind tells me won't make a significant difference. It is less time and cost consuming that way. Also leaves the pleasure side freer to enjoy music. One thing I do find hard to share - the ability to remember what something sounds like in such a way as to form a valid comparison from a previous time. With visual experience one can photograph and hold two or more images so one can look at the same time. There does not seem to an audible equivalent. Listen to two recordings at the same time? So is it rude to question how another member manages to hear differences that might be clearly visible if they were photographed? I do love photography. Unless one uses artificial lighting natural light is different one minute to another. Photographs show this. Unless one is in an acoustically stabilised environment, audio equivalent to constant artificial lighting, one moment will differ to the next both externally and within ones own body. So what assurance would one have that what a person says they hear is repeatable both by themselves or any other person? Much perplexed but what people say that my own experience does not support. |

Some years ago now there was this bloke that said mains cables make a difference. Martin was his name.
He must have been on something, but he kept insisting so I risked a 2nd hand jobbie.
Tested a track.
Swapped the Kimber Standard in.
Heard a difference. Staggered.
The boss agreed. So I wasn't going mad.
Swapped back quite a few times. Tried on other kit.
It really worked.
Mains cables upgrades I have made have improved the sound of the system giving me more music

I remember, Alan, and I respect the fact that you actually tried it. We can't give assurances, we can only relate our experiences. Sufficient numbers of people have reported on mains cables and fuses that there must be something going on. It was amazing to have open discussions about such things at the show yesterday. These are not deluded people, they are music fans delighted at hearing more. I'm sorry that these things don't work for you. |

Alan, If I may inquire which make of fuse you experimented with ?
Having experimented with a number of different brands my experience has varied from bugger all difference through perceptible, to bloody hell !!!
