Speaking of connectors I will not look for electronic parameters, better to look on mechanical parameters and here better don't use scope, meters, distortion analyzers, etc.
N.B. Come back to physics.

I dislike RCA connectors due to the poor mechanical design, I prefer BNC or better LEMO a lot of better mechanical contact.
We have all the tools to measure equipment. We can successfully land men and women on the moon and return them to earth, there's no reason to expect that there's some magic in audio connectors that somehow escapes the abilities of scientific measurement equipment. To suggest otherwise is only to illustrate a level of misunderstanding in the field of science and measurement which should disqualify an individual from even speaking authoritatively on the subject.
We actually do have a way of measuring what you hear, it's called an ABX test, which audiophiles have spent the last several decades failing and then spewing nonsense objections about.
If you really believe can measure all with equipment good for you. I don't believe the same and I don't say isn't necessary to do measurements I only said we can measure all.
To do an ABX test is better to make with no audiophiles.
Do you want to make an ABX test with two different measured amps and said wich one is better as per measurements? I really bet do you do the same like audiophiles.

Nothing about physics here, poor connectors are more prone to fail in difficult situations more of a pathological behavior. A fresh solid connection via an RCA or LEMO will pass unaltered signals. Shielding and grounding is a totally different issue. The non-existent micro-diodes, etc. would manifest as electrical signal aberrations that are easily measurable.

Well, my understandings (not beliefs) are based on verifiable fact.
If you think RCA jacks sound different (a belief), you're going to need to prove that (make it into a fact) before the claim can be discussed. Continuing to discuss it as if it's a real, verifiable fact should be considered abhorrent and destructive.
A connector passes an electrical signal, you have to quantify the signals propagation....and here scopes meters etc are your friend, signal propagation is physics...
Here is a good start:
Wiley: The Fields of Electronics: Understanding Electronics Using Basic Physics - Ralph Morrison
Now as to choosing connectors, this can be fun especially when they are subject to high vibration, extreme temperatures etc etc. I once spent 4 months looking at and testing various connectors, doing test boards and having them tested to the extreme, great fun, did any of them bugger the signals up (digital, analogue and low level analogue), nope not when they were working, they do add some parasitics to the signal path as mentioned some resistance inductance and capacitance, very small and only really affected the very high speed digital signals, of course again this project was not for something as taxing as audio reproduction (it was rocket science😉)
RCA don't have a very reliable mechanical connection and for me the mechanical connection it's very important because form part of contact. Shielding is more efective for digital cables.
Are you ready to make the ABX test with two different measured amps and said wich one is better as per measurements?
Very poorly worded statement (and, hey, I´m also a native Spanish speaker, but I don´t hide behind that or use it as an excuse when somebody contradicts me) .
Truth is: "oscilloscopes do not measure subjective "parameters" (soundstage, prat, velvety, woody, sweet, whatever) , but measurable, repeatable, calibrated physical ones such as SPL, response curves, distortion, waveforms, etc.
You have it backward. Can you find a pair or amps (or, to the topic here) connectors that can be distinguished ears-only, but won't measure differently?
Why would I take an ABX test? I'm not making any claims.
I have nothing to prove.
@DrDyna You don't understand nothing I said, I want more science to make the proper measurements, If you understanding is all discovered are you saying no more progress.
Sure, more science is great, I'm all for that.
That doesn't mean that the science that we have now isn't completely capable of disproving the claim that RCA cables sound different...which it is.
