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.

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

When a product shows nothing to back up its claims, I am pretty sure that it is make believe.

 

And don’t forget to bake the cables.

Wow, a lot's been going on since I've been on.  @holmz  Fantastic measurements of the the Kento Carbon speaker which received glowing reviews.  $40K is near my max to spend on speakers.  I've got to hear them.  Thanks!

@fleschler Not everyone cares about time and phase, so if you dislike them, then you are well ahead of the game as you can likely scratch off Dunlavy, Theil, and few others with a similar design ethos.

"As to my system, you can see a brief overview and pictures in this reviewthread: https://www.audiosciencereview.com/forum/index.php?threads/review-and-measurements-of-lyngdorf-roomperfect-eq.6799/

It’s clear that ASR’s founder has some pretty reasonable gear, and posting it as a virtual system here—while that would be cool—isn’t obligatory to demonstrate that.

There are some oddities, discussed at ASR in fact: he’s tardy maintaining/repairing those classic ML amps; he hasn’t subjected them to his very expensive analyser; nor subjected those speakers to his very expensive measurement robot; apart from some shag-pile he eschews room treatment (iirc in all cases, obviously).

Now there are surely reasons: that gear is heavy; they’ve been measured by others; the amps won’t deliver the "graph hygiene" of a Topping; he gets good enough sound with room EQ at LP; and so on. And ultimately those choices and priorities are his, really. Notwithstanding that I would make different choices.

 

@thyname , nice Mapleshade rack, love their cables too, and such a solid company to work with. If you look in the pic in my system you’ll see the Mapleshade platform/isolation system on the right. Have you tried their cables yet?
