Doesn't wire dia also influence C and L?
I'm thinking of the variation in group delay with larger dia cables as a possible explanation. I'm wondering what the brain would make of the harmonics arriving before the fundamental frequency. What would the effect of harmonic timing errors be on the signal itself?
Can a 48% increase in impedance with 11AWG cable at 20kHz really be ignored?
I don't understand what you are getting at, Ohm's law will only show inaudibly small differences, isn't it? 🙂
To me the lower current allows for using smaller dia cable which are more linear at HF.
Since you mentioned it, isn't you the one looking for spookies. 😀
I agree Panicos, I was only too scared to suggest 16awg cables on AJ's tweeters, it may just start a fire. 😀 😀 😀
I would surely hope so but 'realism' on a hi-fi system may vary depending on what you are listening to. If you like to listen to amplified life rock shows, your system may be very different than one optimised for unamplified jazz type of music.
You sacrifice midrange detail even with the 8" SeasW22, therefore my concern about large cones on midrange detail.

Still,there are people who can hear even that frequency.A friend of mine has demonstrated his ability to me,hundreds of "switchings"🙂 I can't,but when in doubt on something I believe he can help,I call him for a coffee and his opinion.
How about 33% increase on 15Khz?
I'm not really concerned about the small loss in amplitude at HF but it seems to me that it influence detail at much lower frequencies than amplitude measurements would suggest.
In an audio system there is "realism" in some areas,and compromises/sucrifices in other areas.Two good listeners might talk about realism but also be willing to compromise/sucrifice different things.IMO the best way to enjoy "realism" of your system is to try eliminate things that disturb/annoy you when listening.This will "improve" the "realistic" part of your system🙂
No danger of that. Early spring is more likely- the main issue is time from work, I have piles of Southwest free flights.
33% of what? Translate that into dB changes in SPL.
That uis meaningless without knowing source / load Z.
An increase of from 0.01 to 0.0133 at 15Khz in a nominally 8 ohm circuit is audible?
It is absolutely fine to be confident, but if you haven´t got any experience with blind tests in general and this sort of protocol that SY has proposed, then i strongly recommend some training under this blind test conditions.
It is _not_ easy to remain in the same state of awareness during a blind test as during "normal listening" , and therefore some training is essential.
And use during the training period some (known as audible) differences to check for the progress.
Last step should be training with the cables itsself or something comparable.

P.S. For p <=0.05 it still needs 10 correct answers in a 12 trial test.

33% more than dc resistance, 33% non linearity.
Is SPL all that can influence sound?
Read the second part of that post, I don't think it is realistic to try and find all the answers of accurate music reproduction in amplitude response.
dc resistance is determined by length and cross section area of a conductor......are you sure that is what you are saying?
skin effect is all about ac currents not dc....
97 posts and this thread closes....hurry up guys, let's get this done with before Christmass....
Exactly, there are little difference between dc and LF, the problem starts when frequencies get higher.
Wrong.
Now try answering my question. How does that translate to SPL differences? Do you actually know what "frequency response" means?
By group delay do you mean the delay caused by a crossover network? If so, what's the diameter of the cable got to do with how the delay varies?
Or are you saying that a cable (by itself) can cause group delay? If so, by what mechanism?
