Are cables really worth their high price because of their geometry?

My experience is that the tech is not all mumbo jumbo.  That said, in my new system I shopped for cables last and found that the prices in many cases were out of sight.  I found that the cost of new cables even in the middle of most manufacturers product lines were too high as a percent of the total system price, even when discarding the old adage of percentage allocations to different parts of a system which I realize no longer holds true.  That led me to believe that cables have become a good way for dealers to maintain their overall margins, particularly when putting together a system price.  Brick and mortar retailers have high overhead, so that's just the way the economics work.  You can see this same principle at play if you purchase "regular" av cables at Best Buy vs., say Monoprice.  My solution was to shoot for established manufacturers with a good quality "story" and reputation and then find open box or used, which I did.  I feel I got good value that way.

Here we go again.

Do speaker cables have DF?
NO
Amp's have.
So the speaker cable is calculated per DF and length.
Still, resistance is all that matters.
Some had tried it, and the feedback was amazing.

I surmise that most audio cable naysayers cannot reconcile the cable's individual component costs with the final price.  Looking from this angle I can see how high cable prices can rub folks the wrong way.

However, I don't consider the manufacturing costs/retail price, rather, I focus on price/performance. 
For instance:
Option "A" use inexpensive cables
Option "B"  try out a say $200 cable hopefully for free (borrow, returnable).  Then I can decide if there is an uptick in performance, am I willing to pay $200 for this uptick?  I can still not purchase and be no worse than option "A".
With option "B", at least I have choices and additional information (a data point) with zero $ invested and the possibility to elevate my system.  
I suspect that many naysayers are not even willing to try, being emotionally resentful of the often steep pricing and entrenching their resentment with some argument.  

I'm also of the belief that everything in the audio chain matters.  Whether cables should be elevated to component level is subjective.  For me, because I believe cables sound different from one another, I treat them as components.  As I move up the audio food chain, I don't want my cables to be the weak bottleneck.

I agree that a lot of audio cable manufacture's advertisement/marketing is filled with a lot of subjective marketing hype, but I don't it reaches the level as being BS since BS can mean deceitful/lying. 

When researching/shopping for components, I give the most weight to opinions of audiophiles who has purchased/used the component with no skin in the game (like a dealer peddling his product).  If enough voices sing the same tune, I'm of the belief that I can obtain similar results if purchased - the caveat of course is it can be system dependent.  I give little/no value to manufacturer's hype.

Is a person who purchases a expensive audio cable being duped by marketing hype, placebo, or false imagination?  I'd say generally no, at least for the very expensive cables.  Seems most are educated professionals (with incomes enough to further splurge in this high-end hobby) who when you read their reviews/posts, are very serious about the performance of their systems and are deliberate/thoughtful on why they purchased the cable and how it performs. 
I don't believe that as the price of cables increase, their testimony validity decreases.  If so, what's that based on?

Audio BS Facebook group?  Taking a magnifying glass to outliers and calling it the truth is misleading.  You need to get an "impartial" sample size(s) to be able to make educated guesses/claims regarding the population as a whole.

Please help me out on this Geometry idea.
Is it comes to replace all others:
Bi wire
High purity OFC cable
Directional
Cryo treatment
Silver over copper
Skin Effect
Snake oil...
Or all still apply but the geometry was just added to the list?

Do we have any proof (measured, scientific or other), that shows any advantage of a cable with geometry vs a none geometry cable?
Or we just need to take the manufacturer and sales guys for granted?

I need to admit, that the list above, shows of great creativity.
I would also give them the credit of the convincing, as so many fall in and reached to their wallets...till the next idea came out, and it worked again and again.

But at the bottom line, after we all had our lesson, spending on no good cables, How come no one ever wondered, why do different cables sound different on your system?
As if it does, there is a physical or electrical relation between a better sounding and a less good sounding cable.
Did ever, a cable maker stepped up to say:

This is why cable A, sounds better than cable B ?

And please don’t bring up any of the list explanations. as none apply!
I figured it up guys. 
It works and works well.
