I put up some information, with a bit of a tongue in the cheek dig at some beliefs, nothing to harsh I would hope. I have crossed paths with Clave and others before and even though we disagree on many things it does not stop us discussing things on an open forum, with humour and respect even though we disagree on points. It is not the person who that is targeted it is the beliefs that are being questioned.
it is you who are taking it further and reading more into all this than is there, if you cant handle the conversations without having to resort to negative comments then that is your problem.... There is far more in life to worry about than having a few silly 🙂 beliefs questioned... That's how you learn, and I have learnt many things here on DIY audio and had many of my own beliefs and views questioned, if that happens I do further research and if wrong change my viewpoint, its education and it never ends...
😀
Oh I also take connectors seriously, if you want any information on vibration proof connectors for high speed digital applications I have a wealth of information as I did a two month study on it. As stated connections are critical in electronics, well studied and tested in the real world. Automotive is another area of good information, harsh conditions and with drive by wire critical. It not always a good idea to base decision on information from audiophile connector sites and documentation....

I am appreciated on the discussion going on here. Since I know little about binding posts, I was not sure the influence of metal choice in the sound quality.
And people here remind me that a secure connection is the greatest consideration for post making while metal choice basically doesn't matter much.
Anyway, I also believe in science and hope that our discussion can be inspiring and objective.
I know, and I commented it with a wink. Bit it's still voodoo to me - how does a black background sound, and how should any passive component be able to add black background at the end of 2 og 3 meter speaker cable?
I once though I could hear a difference, but I failed any AB test I did. Now I use my energy in room correction (both DSP and room treatment).
I thought the wink was from the quoted sentence...sorry
I think the word woodoo is imprecise and inadequate at the same time since I'm describing what I'm experiencing using different connectors.
No magic involved, only different physical objects.
You can be skeptical about what I'm experiencing, think that I'm fooling myself, consider it impossibile, no problem about that.
Blacker baground is only a way to describe a more focused sound with better contrast due to a lower noise/distortion.
It can't be added, simply different passives induces more or less noise/distortion reducing focus and contrast, the absolute 'black background' is in the original signal.
I've recently did an ABX test via Foobar (see here, if interested) on the same track (the original Vs processed to fix hard clipping).
The waveform was obviously different and in sighted listening ABA comparisons difference was obvious too.
So I also did the blind ABX test an passed it:

First comparisons has been easy to discern, quite as easy as sighted ones but after 5-6 interactions difficulty level raised rapidly, at the end everything seemed equal...
IMHO an ABX listening test done without enough time to avoid fatigue flattens results and the risk of dismissing a real phenomenon is high.
But the real point is another... A positive blind test can confirm beyond doubt a phenomenon while a negative one can't dismiss it beyond doubt.
A negative result should, at least, require investigation and changing conditions of the test with several repetitions before dismissing anything with a reasonable probability.
If we can break electrons in our connectors why did they built particle accelerators at a cost of billions to do just that?
In theory the best conductor = supercinductor will let more noise and distortion through. In passive components you can only experience a loss. If you really can hear a difference, you will not know if it's a little more output from the "good" connector vs a little less distortion. Maybe you can hear a 0,01 dB difference og even 0,0001% distortion (I'm glad that I can't).
It's not that I can't hear a difference (I am actually trained to do so, when I was a sound engineer), but I can't hear a difference in speaker connectors.
Could you do you ABX test, where you record the output (should be exactly the same outputlevel to eliminate this from beeing a factor) from different connectors and ABX test these recordings? Only modification to the recordings shuould be level matching between the recordings.

Of course there is the option of going with Anderson connectors and the silly thick wire they allow!
Its the fumes 
If you have a non linear loss distortion is added.
Also if loss is linear you can lost signal data with attenuation, whatever goes under the noise thresold will be lost and again distortion is added.
This is a good point, brass will attenuate more than copper so there will be a small difference in volume and so in perceived frequency response.
But still some differences could exists, an alloy will have different metal grains, each time signal pass from a copper grain to a zinc one there will be a change in impedance so some signal reflections could occur, smearing a tiny bit the signal.
Neither do I... differences are obviously bigger than that.
Never told nothing against it, IMHO everyone could hear the difference if not influenced by bias and knowing what to focus on.
It's on my to do list but my spare time is not much so it will not be so soon.
No, at audio frequencies and so short lengths as you see on a speaker connector, the change in impedance and reflections is a non-issue. Many times we see arguments in high end relating to HF related issues, but in low frequencies these are not important (impedance match and skin effect is only related to HF)

If the difference between connectors is in volume, then match the volume. ABX tests are valid only when level matched.
I do not consider a 22.7% chance of guessing a "passed" test. It is not totally random, but it is still not "good enough" as one could get lucky and get that result 1 in five tests.
It is much more difficult to be lucky when chance of guessing is 5%. That will happen in just 1 of 20 tests...

Well, what he actually "should" do, instead of endlessly *imagining* what one parameter or another *might* do to sound, is to get a few terminal post samples and try them all using a double blind test, then use the one which is consistently better ...... if he can pick one consistently over the other that is 😉
Slim chance of that happening, of course.
