Why high-end cable manufacturers don't post measurements?

speedbump6: I did not say every. I said specific. 

For example: In another thread, I stated the requirements for sub-woofer controls and "Among others, the Martin Logan x series have all of the above."

Almost every other responder recommended what they own. 

¿Comprende, amigo?

People get criticized for recommending what they own( why wouldn’t they if they went through a process to determine what’s best for the goals they set?) and for recommending product they don’t own. Also if it’s something they’ve never listened to, but based on lots of info from others posting. We are having discussions, conversations. Most understand that everyone has different likes, so they mention what they think someone might like based on what they said they’re looking for ( or sometimes recommend something completely different just because they like it, whether or not it fits with what was asked for) sometimes having a discussion enlightens us to things we had not considered before, it has sure happened to me. You did say something earlier that intimated no opinions were of value, or at the least most, or so it seemed. Sometimes the way we word things appear different to readers than how we perceived it when we posted it. I’m happy to listen to opinions that are given in good faith ( not ones telling me I’m hallucinating when I hear something) I believe I can get a feel for the basic idea of what to expect from others descriptions, though I did recently buy a guitar amp based on what I heard online and what was posted individuals and professionals. I’d say it’s the first time what I expected and what I heard in person was different. Barely spent any time playing with the settings yet, so jury is still out.

So many words, So many posts, so much  time put in your says...
Did you ever try it?
What if I'm right?
And

I am right.

It has records of proof in my previous thread.
Just tell me your
Amp's DF (not the 10000 BS) and
length (not the 4000 feet BS), and
what is the # and length of the cables you currently use.

1. Because, under carefully controlled conditions, the measurements wouldn't consistently reveal significant differences ...

OR 

2.  ... even if measurements could reveal ~significant differences, it would be too hard to agree on and consistently repeat controlled testing conditions. I suspect the differences some people report, if real, are attributable to changes in length, gauge, or fiddling around with connections.  Or to small changes in speaker positions that occur in the process of changing cables.

Mr. B4icu it's not relevant what distance the wire and DF of amp without taking into account the impedance swing of the speakers. You keep on pushing battery cables and I'll stick to reality.
