Guys as usual you attack the messenger and not the message and all the while nobody tries the experiments described.

Whilst I am sharing my observations, please understand that my findings are rigorous and supported by plenty of ABX 100% results.
If I was not 1000% certain in these observations and test results I would not be discussing them.
I note ABX proven effects due to dielectrics, so do plenty of 'capacitor rollers', I find that wire insulation layer pvc and associated ingredients should not be regarded as 'totally inert'.


All materials are magnetic field sensitive and electric field sensitive to some degree and these sensitivities each have multiple dependencies.
Theory conjecture is that the magnitude of these dependencies and effects is of nil consequence and should be disregarded, in practice at audio frequencies I find this is not true for 'typical' consumer audio systems.

:cop:

I've just deleted over 30 posts from this thread, many of which were derogatory and demeaning.

Also noticed are replies that appear to fly just under the radar and to be crafted in such a way as to not just emphasise any technical aspects of an argument but to also put down other view points in a less than pleasant manner. Its also fair to say that some of the replies to these posts are in their own way just as bad.

We always say 'argue your point on technical grounds'.

Please be civil in the way you do this, on both sides of the argument.
 
Thanks.

JN, I observe black or white IEC cables causing difference in system sound, I observe AC extension cables causing difference in system sound, I also observe that removing the black outside sheath (skinning) of my interconnects changes system sound.

So if the cause is pigments, or fillers or anti-fungal/anti-uv etc compounds there must be a deeper reason, superparamagnetism is one property of MnFe2O4, is this of effect at room temp ?.

If somebody could audio frequencies fine measure capacitor connection parameters of a short length of RG59 cable with and without external sheath that might be interesting and useful ?.

You did not approach your observations with any scientific rigor. As a result, you are attributing causation to entities which have nothing to do with what you hear.

The last time I came across an IEC cable making a system difference, it was traceable to a ground loop.

Remember, hum is not the only result of a ground loop, many people have ground loops with no hum. But other things happen.

You need to use a real scientific methodology, and stop claiming you have proven anything. People working 5,6,7 orders of magnitude beyond what you are doing have never reported anything...never.

On the brighter side, now I know why sushi isn't allowed near an MRI.:D

I had no intention of posting here again, but as an observation: guys, you are playing right into the OP's hands. I did try to warn those who were not previously aware that he makes a practice of this kind of thing. Please note that I am simply making factual observations here, and a statement based upon them.

The OP last posted in this thread (unless something got culled in the 30 posts Mooly swung an axe at, and if memory serves, it probably wasn't) three days ago. He has a habit of sporadically creating wire threads on this forum, with what can only be described as the deliberate object of stirring the pot, as Pano so appositely defined it on the one on USB cables about 12 months ago. After initiating what he knows perfectly well is a thread that will generate considerable friction, he then vanishes, to appear only sporadically thereafter, usually with a short post clearly designed to stoke further discord.

Seriously -wire threads can be very entertaining. But when they get to acrimony, above all when that is the blatant object of the OP, it's time to pack up and move on. 30 posts culled says it all. Let the thread die now.

I would like to point out that I am just one of the little people who likes listening to music while sitting in front of a handmade home built sound system, and after the last couple of days I no longer have any enthusiasm left for what counts as debate within technical audio. This will be my last post on diyAudio for the forseeable future, I will look and listen to what is said, but for now, enough is quite enough........ToS

It is a good deed to help others, just point them the answer with subtlety. We all learned and asked questions on the forum at one point and we all have remaining questions.

Saying wires doesn't matter will not be convincing.

I am trying to point that I find that DIYers, like anyone else with store bought systems, question every single component, and the visual one which is obvious and simple is the wire going to the speaker.

It is logical, it is visible, it is big, it is dead simple, it can be swapped very fast without trouble, and IT COULD BE the thing blocking them the superb bass and midrange that they crave for.

So the thread it relevant. People want to know to which extent they should spend on wires, or take the trouble to braid 8x 18 gages in a 1 inch pattern, or if the color of the wires matter, or if they need isolator from the carpet... etc ad infinitum.

Why? Just don't waste your valuable time on threads the sole purpose of which were to deliberately stoke acrimony. Like this one. Focus on genuine threads. However, if you prefer, I'm off.
 
Max Headroom said:
For data, communications etc systems this assumption is 'valid', however for base band audio I find that these fundamental properties of susceptibility and hysteresis and loss are of importance and IME define the audio band sonic signature/finger print of materials and systems.
Physics says the opposite: the insulator used may make some difference for RF but no discernible difference for lower frequencies.

Logic is logic, no skill sets required.
You understand some behaviours of 'electricity', that doesn't mean you understand all properties of 'electricity', same as everybody else.
Perfect logic based on a false premise will lead to a false conclusion.

It is known that red and black wires are not identical, Red send-Red return is not the same as Red send-Black return.
This argument is again not logical.
My point is that if they are different then the main requirement is not red-send+red-return, but instead 'do the same for each channel'. Channel balance is the issue. Our ears/brain can easily filter out minor response variations which are identical in both channels but interchannel differences are more easily heard.

All materials are magnetic field sensitive and electric field sensitive to some degree and these sensitivities each have multiple dependencies.
Are they? I thought many materials have a magnetic relative permeability which is equal to 1 to quite a lot of decimal places. Has not JN just said so?

Experience through history says that in the audio band there are materials electrical behaviours dependencies that can and do influence if not define audio system behaviours.
That is your claim. In reality for almost all short analogue audio cables the claim is false. An audio cable is essentially a trivial potential divider. The detailed properties of the shunt and series parts are of no consequence provided that the series part has sufficiently low impedance (compared with the load) and the shunt part has sufficiently high impedance (compared with the source). In practice it is the latter which is most likely to be a problem but even then (longish cable, poorly engineered source) the first effect is a little HF rolloff. These are simple facts; facts which our modern world relies on.
 
Yep, you are right. I just need to be told this - fragile as I am. A lesson learnt. ToS


We all love you very much, I especially, I would show you in person inviting you to eat like two good friends, but it would be a bit expensive due to the extra expenses ....... ;)

Just have fun and remember that there are two kinds of people:

Those who talk a lot and think little
