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.

1) It is a good thing that measurements can inspire companies to bring the performance up to a higher level. Consumers should be taken seriously.

2) We listen to sound that is generated by components who work on rectified, filtered, stabilized, modulated, transformed electricity. Everything between the grid matters. That includes all cables and connectors, just as capacitors or diodes for example.

3) Cable companies should not make false claims and deliver proof. I can agree on that part. It can be hard to listen for those tiny changes. Recently I discovered that a cheap Van Damme tourgrade starquad bested my Siltech. I am a pragmatic audiophile so I sold it on eBay.

4) On the other hand, people should not make claims about the hearing capabilities of other people. If multiple people subjectively can describe parameters of a component that can’t be supported by measurements (yet) it should be taken as a starting point for further investigation. We don’t all have 1000+ people at hand to conduct (DBX) tests for any statistic significance. Or have expensive test equipment. Interpret measurements correct and be humble about your personal bias as a tester or audiophile. I can live with that.

Enjoy your system and music but don’t engage in trying to convince others that you are right. You will lose that argument in any evidence based discussion.

Thank you. Keep up the good work at ASR. When I am describing my observations about components or cables, it is not about being right, but being supportive to other people. Like others are doing by measuring. Being ’right’ is not the only motivation.
