Nearly all manufacturers do not advertise/exhibit their product measurements? Why?

After my Audio Science Review review forum, it became apparent that nearly the only way one can determine the measurements of an audio product is wait for a review on line or in a publication.  Most equipment is never reviewed or is given a subjective analysis rather than a measurement oriented review.  One would think that manufacturers used tests and measurements to design and construct their products. 

Manufacturers routinely give the performance characteristics of their products as Specifications.  Those are not test measurements.

I searched the Revel speaker site for measurements of any of their speakers and could not find any.  Revels are universally lauded for their exceptional reviewed measurements.  Lack of published manufacturer measurements is true for nearly every speaker manufacturer I've searched for on line, perhaps several hundred.   Same is true for amps, pre-amps, DACs, transports, turntables, well you get the picture.  Do they have something to hide?   I doubt the good quality products have anything to hide but poor quality products do.  

ASR prides itself in providing "true" measurements that will aid in purchase decisions.   Why don't the manufacturers provide these measurements so that reviewers can test if they are truthful or not?

Then there are the cables and tweaks for which I suspect that there are inadequate tests available to measure sonically perceived differences but which objectivists believe don't exist or are "snake oil."  

Well, please chime in if you have some illuminating thoughts on the subject.   

I would have loved to see manufacturers measurements on my equipment and especially those that I rejected.

My comments: @chmaiwald Great!  Food comparison.  McDonald's burgers measure better than any other fast food burger for consistency.   Despite that, I only eat Angus ground sirloin burgers at Le Petit French restaurant because they taste better to me.  Amir's answer-Le Petit's burgers are too expensive so I am throwing away money when I could have purchased half a dozen McDonald's.

From the top of my hat I can‘t think of any hobby or whatever gives you pleasure where least personality is something widely accepted as the ultimate goal.

“I went out dining, and let me tell you, that casserole was so accurate. I loved its linearity. I measured it.“

I‘m joking of course, but I think there‘s something to it.

This thread is like a group therapy session for 4th graders.

And you were hoping to give up that teaching job and travel.

One manufacturer that I use that posts specs and measurements is Auralex for my room treatments. Of all the things you can screw up in a system you don’t want to screw up the room. I find their products an excellent value as well. They were really helpful answering questions about my setup too and offer a free room analysis, very responsive. If anyone reading this hasn’t bothered to treat their room yet don’t wait. If you look at the pics in my profile you can see various treatments, bass traps, absorbers, diffusors. You can’t really hear what your system is capable of until you tune the room. DSP is limited in what it can do:

They have an app you use to design your layout too:

Are you deaf (or rather taste depleted that you can’t tell salt from sugar)?

I believe you have lobbed that insult more than once.

Can you tell me specifically what I wrote that leads you to think I have poor hearing?

My discernment for characteristics in sound, both large and minute, is routinely put under scrutiny for my job. I make a living with my hearing. I can't just brag about my hearing on an internet board.   If my hearing sucks, I lose my job.  How about you?

I’ve also put my hearing under rigorous tests where I don’t get to "peek" and ACTUALLY use ONLY my hearing to see what I can tell apart. That is: blind tests.

How often have you truly tested your hearing - your hearing ONLY! - rather than when you know what you are listening to? If you continue to brag about how you can tell things apart in "sighted" tests where you know different gear is being switched, that’s about as "impressive" as saying you can tell me what number the dice will roll...but only if you first get to look at the result after the roll.
