Capacitors test expertise

Hello,

I have few caps

Audyn QS6, Qtext4​

not tested by anyone yet, no reviews at all conducted.
I'm looking for somebody with the expertise and experience willing to do tests and share his impressions.
I'll supply the caps, but based on latest Canadian postage rates, shipping is quite unaffordable/reasonable in comparison to the cost of the caps and else..
Thus I'm looking for somebody in Calgary ( a long shot) and surrounds in order to avoid the shipping charges.
Any other suggestions, please?
Thx

Using listening tests like this can lead to you to incorrect results. For example..

Two capacitors may have different series resistance. This isn't a bad thing in itself but they may change the tweeter level a little. If it was too loud one capacitor would sound better and if it was too quiet, the other capacitor would sound better.

In that case it isn't the capacitor you are hearing, but the overall circuit which you would judge. In any case you would expect to adjust the resistance in the circuit.
 
So?
All capacitors show straight lines, all SOUND THE SAME, much to the chagrin of Capacitor Religion Priests.

Only exception is worst quality ceramic capacitor.
It is a WELL KNOWN fact, you just "discovered" that water is wet and fire is hot.
Is this your "proof"?

This forum is chock full of "Priests" writing page after page arguing huge differences they claim to hear, easily, between Polycarbonate Polyester Polystyrene Polypropylene and even old style Paper Oil.
HUGE differences are claimed. 🙄

Thanks for uploading tests showing they do not exist 😄
 
Sonic signatures and comparison to other caps. Application specifics...
I used QS4/QS6 in many designs, basic films caps, they did well the job as good as my SCR MKP = Solen capacitor ?
I prefer now to use Mundorf Cap Evo or SCR smartcap, the sound is more precise. The form factor of these caps reduce the loss factor by 40% and it is perfectly audible.

It was not my intention to open the can of worms, not at all, sorry.
Who's Steve?
"The Sound of Capacitors" - do the oscilloscopes produce meaningful sound? There is no mentioning about correlation between the graphs and sound experience.
It looks to me the referral to the article is not complete... Are there more parts of it?

Thank you.
Between Above mentioned Audyns, Standard Z cap, Solens Fast Cap (as you see, I do not have intentions to invest in exotic caps, due to the nature of my applications) I find difference in sound signature based on the application. Some appl take better Z cap, other - Qtex4, and else.
I was looking to get some impressions in the format of T,Gee's reviews.
