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 also add that if you want measurements for a cable, I am happy to do that.  While I am getting a bit exhausted from testing so many and finding none modify the output of the audio system, I am still here if you want to have that data.  Cables are small and light to ship so not much burden.  And I usually pay for return shipping so you are only out of pocket for the expense of sending it me.

If you were never interested in such measurements but created a topic asking for it anyway, then say so and we go about our business instead of dealing with a Kabuki theater.

@amir_asr , well you finally engaged. All you posted was your opinion of a system you never heard (mine) with a cable you never used (the Mapleshade Digital IC) and clearly have no idea or evidence to back up anything. Well, let’s go with that.

OK, so let me give you a track to run on. This is an example of a cable review by someone who tried the Mapleshade cables BEFORE coming to a conclusion. I would say my experience was more similar to 3 people that came to the same conclusions in this article:

@amir_asr ,

You made a BIG mistake, when you didn’t align your system within your room. DSP is limited in what it can do. I think you can rectify your mistake if you work on your room (which is why you won’t post pics and FR if I am not mistaken). You may not agree with @fleschler on everything but the guy gets props for knowing how to build a room. Maybe you can start a build thread for a new listening room/studio?

Those expensive Revel speakers you own are going to waste I am afraid. You are worried about my wasting $250 and hear you are shredding dollar bills every time you listen without your room tuned, a mistake for an average listener but a disaster for a reviewer.

My info is based on the disdain you posted for room treatments in your review of the Paradigm PW Link. If you updated your room we would all like to see pics. Thanks

That is precious calling Amir a reviewer. 

He is not that he is this.

A shill is a hustler or con-person who tries to convince other people to buy something or think something is great (shilling). The shill has ulterior motives for their actions, usually because they are the actual seller or have something to gain if the product sells well.

@juanmanuelfangioii , it is what it is. When I look at some of the rooms of our members in the virtual systems area it provides context and many of them are simply awe inspiring like these. If you are putting yourself out there as an expert I think it takes more than just a microphone and a computer. If @amir_asr posts something (anything) let's see if he can walk, or if all he does is talk (spitball):
