Fuse and Cable Directionality

[Analog Scott]

Finally, a very good question. Anyone care to take a stab? Alternatively you couid go read the AudioQuest paper on directionality and noise in audio cables, it’s strictly up to you. See my post earlier, was it last week? Exhibit B

What good would it possibly do to have a super duper conducting Graphene fuse wire when the entire rest of the system is copper, including the end caps?

As much as adding any other sort of super-duper expensive directional fuse?

Pop quiz, how is Novak Djokavic like a directionality skeptic? (Scroll down for answer)






They both have short fuses.

OMG, did China hack the AudioQuest website? Did they go out of business? What’s the story, morning glory? Did they stumble on this thread? Did they recant? Web site under construction? Did they just sign up to be a donor at ASR?

Besides, Graphene is defined as a two dimensional material, if you make it into a solid 3 dimensional material like a wire it’s no longer Graphene.

I believe it is about eliminating the 'weakest link' than to try and improve anything else in the chain.
And I am still not sure where I stand on fuses yet. My system sounds better this week after adding a nano fuse in my Lumin U2, but I've also been breaking in a new LHY SW-10 audiophile switch. I will remove the fuse this weekend and insert the stock fuse to have a good listen.

I don’t know. Just get 404 webpage not available notice

Cable Directionality: It's All About Noise

If you’ve ever wondered about the arrows on AudioQuest cables, read any of our educational materials, or merely followed any of the online chatter regarding our products, perhaps you’ve wondered what this “directionality” thing is all about.

I guess. That was remarkably unconvincing.

 

[Robh3606]

That's an understatement! Found the source for the pseudo science.

The whole thing is so ludicrous! Just think a minute all the leaded parts could have "reversed" leads They are precut to length and binned prior to wiring/manufacturing.

Then you have inductors that can be wound reversed, Then when you install there is no polarity so "right" can be reversed at install.

Let's do a coin toss say 50% are right.

Then you reverse one cord or wire, leaving everything else as is and poof it's fixed!

I don't buy it!

I challenge anyone to prove fuses and wire are not directional. And yes, I know what you’re thinking: “but it’s the responsibility of the person making the claim.”

Can't prove a negative.

these things are not proven. Proofs are strictly for math. In physics we look at the existing evidence and go with what it tells us. I can just as easily challenge anyone to prove there are no pink 5 legged dwarf elephants on the moons of Jupiter.

I challenge anyone to offer objective verifiable evidence that fuses make any difference in the actual sound of a component or that cable direction makes an audible difference. Let's look at the non anecdotal evidence and evaluate it. If they make an actual audible difference in the audio signal that difference will show up in objective measurements in that signal and will be reliably detected in well designed bias controlled listening tests.

Let's see that evidence.

 

[Atmasphere]

From the Audioquest website (link just above):

A conductor’s asymmetrical surface structure causes a directional difference in impedance at noise frequencies and very high interference frequencies. Due to skin-effect, such high-frequency energy travels almost exclusively on the surface of a conductor, giving significance to the directional difference in impedance at these frequencies.

For a 20ga bit of wire, skin effect might go as low as 80KHz, depending a great deal on the kind of signal (usually RF) and the strength of the signal. However if there is directionality at those frequencies, no-one has ever measured it and of course no-one can hear that high either.

The idea that fuses or wire conducting AC signals are directional is extraordinary, so you are on the hook to provide the extraordinary evidence.

I must be a mind reader.

Very doubtful.

Verifiable evidence? The term directionality is completely subjective. I can say 50,000 audiophiles have heard directionality themselves, and a handful of skeptics say no, they don’t hear it or they won’t try. I’d say, objectively looking at those numbers the ayes have it by far. The evidence that directionality is real far outweighs evidence to the contrary.

That’s where we stand right now. You can’t prove it with measurements, you can’t prove it with math, you can’t prove it with photos of the wire surface, you can’t prove it with logic. You can only prove it by listening.

 

[Geoffkait]

Very doubtful.

I knew you would say that.

 

[Analog Scott]

Nope. It's 100% objective. Particularly with wires and fuses.

 

[Geoffkait]

Nope. It's 100% objective. Particularly with wires and fuses.

But we already showed that objective observations, I.e., measurements, aren’t convincing. Blame it on the bossa nova. Besides, as someone just pointed out, you can’t prove a negative. As a general comment, I’d opine that fuse skeptics are a looking very much like outliers in the overall scheme of things in the sense on one hand more than 120,000 audiophile fuses have been sold yet there are very few fuse skeptics.
