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.

Let me rePhrase it.

“How can I tell the difference between your story and a fable?”
How would I know whether it is true and a real thing or a psychological thing, or even just a story.

This is the essence of chat rooms and the internet. Of all the stuff you read how do you filter out what is relevant to you. In my opinion measurements of a product are a poor indicator to whether or not you will like it. A good indicator is customer reviews. Look at the opinions of people who bought it. I am NOT a believer in the blind test unless you have a panel of trained listeners and the proper setup. I am a BIG believer in the customer knowing if something is good or bad. If you want to know if product X walks the walk check Amazon, Crutchfield, Audio Advice, Sweetwater, Guitar Center, etc. for customer reviews.  Then check the forums and some professional reviews. Then audition it by leaving it in your system for a few weeks and see what happens when you take it out.

If there was one measurement that was universally best for everyone every manufacturer would produce their gear to fit that measurement in order to compete. I wish that were true but it just isn’t.

@laoman +1  He won't even post measurements and pics of his own system. No one will make fun of him here, this is a thread about measurements.

Did he just show up to throw up or is he going to throw down? 

"What should make you upset is folks paying orders of magnitude more, only to get a less performant audio device."

I think this about sums it up. Got to save the world from itself.

I feel sorry for the people who blindly believe the BS you're throwing down on your channel. IMO, it's irresponsible and a disservice to the hi-fi community.

I was done with ASR a while ago, and you haven't changed my opinion.

Because once you know, you know. And I DO know. And I'm old enough and my equipment is good enough that I CAN hear differences when I swap out (whatever piece of equipment you'd like to insert here). I trust my judgement. IOW, I trust my ears, (whether you can measure that or not, I don't really care). I don't need your measurements or validation. I don't need your approval. I don't need your channel. And I absolutely don't need your passive aggressive, condescending snarky comments.

Have a great day.

You started out wanting measurements and a list of equipment, and now it is back to being that none of that matters, and it is all in the ears of the beholder.

@holmz

I felt there is no other way for you to get the info you were requesting about gear.

The measurements of the gear are different than the measurements of how the gear behaves in a room right?

I advocate getting the room right first and yes, in room measurements can indeed make the trial and error process a bit faster (and maybe even less expensive).

Now, to answer your question to the OP of how to separate the real deal from a fable I can’t tell you a single measurement that will get you 100% guaranteed satisfaction that your money was a good investment. If you know a better way than auditioning it in your own room I am open to trying it.

I would not recommend just taking some expensive speakers that measure well and sticking them in a room with bare walls like some of our scientifically minded guests. For casual listening, fine. For critical listening and professional reviews maybe get some feedback from a knowledgeable third party like Anthony Grimani at www.sonitususa.com or Jeff Hedback at www.hdacosutics.net.
