Why do you think Bi-Wiring improves the sound ?

To explain , when I said converting to bi-wire I meant adding 
speaker posts and re-configuring the crossover wires .
One guy did a test using individual wires of 18 gauge ( 1 @ for per post )
after liking the bi-wire configuration he re-wired the crossovers back to a single wire setup and then used both 18 gauge wires ( 2 @ per post )
he  like the sound of the bi-wiring better !
so increasing AWG was not a factor in his conclusion .

It does seem to work for those who have tried it
but there is no way to measure or prove why it seems to work .

This is why I am asking the question .

As for kool-aid  It worked for the Grateful Dead !

Thank You All

I mentioned that 3 people converted ( added 2d pair of speaker posts )
to bi-wiring and liked the results .  All three had already upgraded the crossovers with higher quality components ,
I just got to the speakers yesterday ( after having installed the same 9.5awg wire from the amp board to the new Cardas speaker posts,
the same 9.5awg wire I used to put together my speaker wires )
when I installed Cardas speaker posts with the next upgrade it will be the wiring to the crossovers ,
one step at a time to evaluated the effect , the bi-wiring if I go that route 
would be the last thing I do .

It seems the experiences , opinions and even the manufactures are 
on both sides of the benefits or lack of .

I just have to wait until social distancing over so I can go over to my friends house and listen to his newly bi-wired speakers .

Thank you for your offer , since you are a Thiel owner you might have read about my theroy on seperation of polarity on the Thiel owner forum.
@chorus 
Thank you , 2 of the 3 who converted are using 18 gauge
for the tweeter/midrange and 14 guage for the bass .
This is another thing to consider if I go to bi-wiring .
@mrklasou
You have done testing ! Something that my friend and I have been doing
for many weeks, upgrades or changes on our systems , which in the end is the only way hear what works or doesn't .

I read all the posts and appreciate them all , this hobby is a constant learning experience , at the same time I'm trying not to fall into making it a money pit .

@ieales    
Thank You for the link, I read it yesterday , very interesting .

The question is does it improve the sound ?
i.e. does the sound stage increase , get deeper , do you have more of a 3D effect , is the music clearer or sharper ?
I asked the question because I can't
( as a retired biomedical equipment technician ) grasp why it seems to sound better to many who have tried it
( without increasing the overall awg ) ,
but I had the same feeling about power cords and outlets until 
I tested and heard the improvements so I am curious about bi-wiring .

As for Glenlivet , I prefer Glenfarclas .

you have an interesting argument , I'm going to read the link and your response at least one more time .
I'm going to assume that they " qaucustics " used thier own speaker and cables .

No I did not add speaker posts , have not modified the cross over boards .
 The question was does bi-wiring inprove the sound ?
I should have asked if bi-cabling or 2 seperate runs of cable sound better ? especially if you used one cable for the positive and the other for the negative posts  ( have any of you tried this set up ? )

My speakers have 2 crossover boards ,
one for the bass and the mid/tweeter is seperated on one board ,
sharing the speaker wire input , easy splitting for bi-wiring .

@sfischer1 

Thank You and very well presented .

@ieales

Negative retorts are not appreciated ,
you have your opinion about the subject as do others ,
respect that's R E S P E C T to quote Aretha  .

I think I'll listen to her album next .

@mirolab
I'm disappointed that your efforts didn't produce positive results .
I looked up images of the 801 S2 speakers and was able to find pictures of the crossover board and of a modded board .
How did you bi-wire your speakers or where did you seperate the 
bass from the mid/tweeter ? 
Please provide us with more information .

For my speakers it would be easy since the crossover boards are already seperated and both are connected at the speaker posts .
But I'm still not convinced or curious enough to try bi-wiring yet .

So Do You THINK bi-wiring improves sound ?
