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.

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

Food is the same as the music.  It is the creation.  Don't confuse that with playback which plays similar role to the plate that the food comes on.  You don't want to have a dirty plate and you certainly don't want your plate to add flavor to your food.  Some of you seem to not only want to violate these rules, but also pay hundreds or thousands of dollars for the privilege of it!

That aside, was this whole thread a farce?  You actually don't want to see measurements for cables?  You were playing with us?

Accuracy is a myth in audio playback, no system sounds like live unamplified music, so why not just use what you enjoy to listen to.

Are you here to throw more spitballs again? The guy that measures doesn't have any measurements about his own system? Embarrassing. If you are experiencing "technical difficulties" please post what they are and I am sure I can help, NP.

Don't tell that to a lot of people around here.  Many think the purpose of the audio system is to replicate live music! 

But yes, you are right that a recording is never the same as a live presentation.  Once created though, you don't want to a) put in tweaks that make no audible difference but cost money and b) overlay the same tonality on everything you play. If you do, that is fine but just don't advocate it as being "higher fidelity."  

Mind you, as you say, you are welcome to do (b) but just don't keep saying that is what people should do.  Studies show that we all like accurate sound when only the ear is involved.
