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.

@kota1  Yes, that is the sad situation.  Possibly 100,000s of audio enthusiasts believe the same way although some  may not have adequate resolving systems to distinguish one cable from another (or other mismatched equipment problems, room problems).

I had to "prove" to my neighbor that his Pangea power cables were ruining his potentially high end sound.  I did not say I was certain that was the cure for his extremely ragged frequency bass response and his other sonic ailments, but he was open to it and it worked with just one cable to his amp (times six cables=he has a high end "sounding" system now).  Totally flummoxed (and now ecstatic) for a former electrical engineer who had believed the opposite-power cables don't matter.  

Anytime someone says where's the scientific proof that all cables sound the same, I'll send them your article.  

@fleschler , the enraged cannot be calmed by any type of proof, let alone scientific proof. Can you imagine our "scientific" guest being shown proof and exclaiming, "OK, you are right, I am wrong, sorry" Not gonna happen, heads will explode.

The point of science is that anyone who wants to check the data can conduct the same experiment, under the same conditions, and get the same result. The vast majority of enraged posters you see here and on other forums won’t do that because OMG, what if they are....wrong?!?!

The one paper I posted on improving your in room listening response states the obvious. Listeners prefer a flat smooth frequency response in the room. I would start there BEFORE you try testing and hearing a difference in your components.

Must be a Down Under thing? 

@jerryg123 usually I blame the spell checker, but in this case the ‘o’ and the ‘i’ are adjacent to each other and I typed it in wrong… but it looked so good, it was not worth correction.

By the way it should be, “too nuanced”.
