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.

"The industry is transforming though because if they don’t measure, then I might. :)"

What unbelievable arrogance. No wonder people in the industry regard your site as a joke. You still have not answered if you actually ever check whether Yang sends you off the shelf products or cherry picked ones. This is now the fourth time I have put this to you. Scared? If you do check, show us scientific evidence that you do, else it is just your statement. Perhaps make a video showing an independent person check as you open an off the shelf product and one sent to you.

That was a quick and interesting response.

After having read your reply and getting past the fake outrage, your answer is "No." , you do not check. That is alright, but it will always leave you open to questions.I say fake outrage because no allegation or insinuation was made; a simple question was asked. I could say that you protest too much.

Now some advice for you. If you got off your high horse and allowed some discussion in ASR, none of these threads would ever have materialised. It is your arrogance and intransigence in throwing off anyone who disagrees with you that annoys many people including your own minions. Look at your appalling treatment of restorerjohn, (yes I know you did not ban him, but you dismissed him in a particularly nasty way), on your own site. This was a disgrace.

One final point. :You stated: "Keep in mind that these are not mechanical product subject to large variations. Yes, there can be minor differences in performance of components but nothing significant can be achieved."

Amir this is blatant nonsense. Are you saying that adding better quality capacitors, improved shielding,  an improved power supply, high voltage transformers and decoupling the power supply does not lead to a significant improvement?
