Just do it over and over for 30 times and you will fall out of your chair at the improvement. |
Rhapsodi, about six years ago Lloyd Walker of Walker Audio, telephoned me to reverse the direction of the fuse in his speed controller for turn tables. I did as he said and he was right. Why? I had no idea. Much later when better fuse came out from IsoClean and Hi-Fi Tunning, the IsoClean fuses had clear markings with an arrow.
I knew the direction of my twist on fuse connectors, name with the arrow pointing into the component. I have repeatedly compared IsoClean fuses with the proper direction for the arrow and reversed. The proper direction always sounded better. I did the same thing with Hi-Fi Tuning fuses and they always sounded better one way than the other, although there was no consistent way to predict this. Since then Hi-Fi Tuning has conceded this and now marks their fuses.
Listening is always the best check and on many units one direction is quite superior. If you go into the unit and find the two ac leads to the transformer, you want the arrow pointing to the side where the resistance is lowest to the blade.
It always amazes me that people will not just try changing the direction and seeing if it makes a difference. But you can lead a horse to water but not make it drink.
There are two other things that I do with all my fuses, but you didn't ask about that. |
Rhapsodi, I don't think their is any convention. Most the holder is just two sets of clips.
Take the fuse out and use a meter with one lead on one of the clips and the other on one of the ac IEC blades. You want to identify the clip with the least resistance to the blade. The arrow of the directional fuse should go from that clip to the other.
Sebrof, I certainly don't try everything that people come with, but this was so easy. Incidentally, many were strongly suggesting using copper tubing over the chassis IEC plug. There was even a video showing its effectiveness. I tried it and found it worthless. I guess it would depend on how well ones power cords are designed and made. |
Stanwal, I had a guy send me the magnets to try. I did and heard no benefit. I assume you tried changing directions before you went over to the blunt side? |
Sebrof, could be that resistors don't matter that much. It also could be that some companies check wire pull direction and resistor direction before assembly. Resistors would be easy to do consistently given their markings.
I don't know how some stick with the limited understanding of EE so close-mindly. I still remember in EE classes that engineering faculty want to "stick with the formulas regardless. |
No, Simply_q, yours is the close-mindedness I am talking about. Just try it, if you hear nothing, I will apologize and add this to my list of things like music absolute phase that some just don't hear.
Timrhu, I expect that the painting is done while they are still connected one to another, but there is of course the possibility that all are wrong, just consistent. |
Simply_q, it is irrational to refuse scientific observation and to claim something is scientifically impossible. You are right that it really is absolute polarity, but many call it phase.
If you reject out of hand, there is no basis for anyone heeding you. |
Simply_q, simply put, you don't know what you are talking about. You say, "there is actually something physical behind it." This is just nonsense. How would you know there is nothing "physical" behind it? As I said there is no merit in heeding anything you say. |
Simply, let me see what does observation mean? Watching, listening, measuring, ie. using ones senses. What does scientific mean? Being as objective, seeking scientifically transmissible data, measuring with valid instrumentation, ie. being as open to what one is focusing on as possible.
Johnsen coined the word. I can see where it is more valid than phase that is most commonly used by those interested in acoustics. Clark has been in my room and he is a madman about this.
I repeat my earlier statement. You are close-minded and apparently fearful that you will hear something, although the nocebo complex, hearing nothing because you believe you won't may affect you. |
Simply_q, I taught the scientific method for 47 years and did much scientific research. You use such stupid notions that I am inclined to just drop the discussion. You seem to think that scientific observation avoids the human senses. My point is entirely that you will do no observation. I am fine with your mindlessly avoiding a possible improvement in your sound reproduction. That is fine with me, but your suggesting that anyone trying changing fuse direction is an idiot and unscientific or "physical" as you say. You, sir, are the unscientific one. But alas, I am bored with you and your mindless ilk.
Rhapsodi asked and I have given my best experiences. The end. |
Bdgregory, I too find I am skeptical without some explanation for why a tweak might work, but I am also convinced by a demonstration. I have heard nothing that would explain why fuse direction would matter, nor why there might be differences between fuses except for the materials in fuses, etc. My experiences with tweaks run the gamut from worthless, such as copper tubing over the pc entering the IEC, to minimum value, such as the Brilliant Pebbles, to a great improvement, such as isolating the pcs from the floor and walls, and variable tweaks, such as quartz disks made by Acoustic Revive and others. In some placements, they do nothing, in other they do wonders, and yet in others they are terrible. |
Dmailer, I found this always to be the case, regardless of fuses or components. The proof is in what you hear, of course, but with the IsoClean fuses it is always with the prescribed and shown fuse direction.
It is just amazing to me that some will not even try it. |
