I mean, how did they come up with those thresholds?
I'm not up to date with the cable threads so I'm not sure exactly what you mean. When I joined the forum, the folklore was that silver brightened things up and conversely, if you needed to tone things down, coper was the way to go. These differences were not thought of as 'minuscule' and were reported by people with less than perfect hearing.

Just as an exercise in thinking, might we say that as these folklore claims were looked at, they were found wanting, so they reached into areas near the threshold of human hearing to maintain validity?

Of course, I'm only theorizing, maybe Big Shot or some of the others will weigh in on this.

If the difference in cables is from its construction and materials, then why is it necessary to see it? The sonic signature should still be there whether you can see it or not.

The new forum should be interesting. Yesterday, I bought a Blue Dragon Sennheiser cable. I still haven't heard any difference with the Cardas cable, either. I plan to buy other cables and will see what happens with electrical test equipment.

Just my 2cents.

I think to make the conversation go a bit smoother that you could refrain from labeling things as "folklore claims". It's those things that seem to always get peoples hackles up and can cause topics to get off track.

JadeEast, you are absolutely correct.

From my original post:

If we are the "Science-Based" segment, we need to develop a non-inflammatory terminology to refer to the group that develops, what we view as, non-verifiable prevailing views? That is the purpose of this post.

Do you have any suggestions as to how we might refer to the as of yet, unverified prevailing views? It is important that it be non-inflammatory.

^Use a foreign, or artificial, word. 99% of the readers won't understand it and thus it will be neutral.

Belief or opinion.

In my mind belief insinuates that it is probably not true. Stick to opinion.

Why not call it "observations"?

I would agree that opinions and observations are both less negative sounding than beliefs.

I think this objective idea is a great one, but I am not sure if I understand how it is going to work.

How are you going to be able to prove or disprove scientifically, if a certain pair of headphones sound different after 200 hours of burn in, compared to the same pair brand new?

Is there a device, computer or instrument out there, besides the human ear, that can make this determination?

If you had a good dummy head, or other device that can accurately measure the frequency response and other parameters of the headphone, you could do it easily.

It's not about proving or disproving using some specific equipment. It's about providing the freedom to question rationally. It isn't against the law to post a subjective impression in an objective forum either. An observation leads to a hypothesis that can then be tested. That's the process that leads to evidence which leads to proof. The key is free and open discussion.

See ya

Thanks for the answer. That is good to know.

Get 15 or more people to listen with two different cables - one burned in and the other not. They will not know which is which. If their preference for one over the other has a pattern that significantly differs from random (ie. half prefer one and half prefer the other), then we can say that burn in likely exists. Then we should replicate a few times with different people at the next meet just to be sure.
