What direction should Hi Fi tune fuse be installed

How about magnets. Magnets enhance the directionality of ac passing thru them much the same as cryo treatment of metals and conductors enhance and unify the direction of their molecules. Results are better sound. Improved dynamics, lower noise.

"If you think this is Dumb, then in effect, you think high-end audio and audiophiles are dumb."

No, just wasting this much time talking about fuse directions.

Most of the rest is of more interest. Well, I gotta say with the exception of most of what Geoff likes to talk about in the interests of softening up any desperate suckers out there that might buy any of the crap he has the nerve to sell.

TBG, I think that your second previous post, which was addressed to NoNoise, may have been intended for someone else.

As Mapman indicated, the thread appears to have pretty much run its course, and opinions on all sides have been pretty well covered. As is usual in debates such as this, none of the opinions of any of the protagonists will wind up any different than they were at the start of the thread. Others who may read the thread will of course form their own opinions.

There is, however, one thing which has not yet been addressed by anyone other than me (and to some extent by Frogman, in responding to one of my posts). If any of those at the believer end of the spectrum wish to comment further, they may want to consider providing a description of what specific steps they took in their assessments of directionality differences to assure that the differences they heard were not the result of extraneous variables. Such as those I described in an earlier post, namely differences in contact integrity, equipment being in different states of warmup, differences in AC line voltages and noise conditions, etc. And note that I have not even mentioned until now the vagaries of aural perception.

As I indicated in my earlier post, it seems to me that eliminating those kinds of possibilities requires, as a minimum, that the fuse contacts be cleaned, and then that the listener makes several comparisons while going back and forth between the two directions several times.

Good point Al.

If you want to convince skeptics, some due diligence in testing process will go a long way, rather than just saying I hear it so its so.

Or we can just all go find something more productive to do.

Almarg, certainly ceteris paribus is sought in a good experiment. When I did my experiments with fuse manufacturers, I did treat all fuses with AudioTop and even tried to clean fuse holders, but many are very difficult to do this, but of course, I am holding an uncleaned fuse holder constant. I also held warm up constant as it took me about equal time to change outside fuses. Of course, listener fatigue was not considered, and I did get bored. You didn't mention that directions might vary from one component to another. I only tested on an amp, but then did some further testing on my preamp.

All of this started long before high end fuses were out. When I got my first Walker Audio turntable, he suggested that I switch the fuse direction in the motor controller. I heard an improvement one way.

You also failed to mention how you really go about this when there are multiple fuses in a component. I have sought to learn the direction from hot to neutral throughout the component. Some manufacturers know and others don't. Basically, I have given up with such components.

I dearly wish someone did an accuracy measurement between the music signal going into the component and that leaving it.

I don't think you can dismiss a difference on the basis of traditional EE laws.
