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.

Here you go @fleschler

I suppose that we can talk about whether that is important or not.

 

 

@kota1 You are so right!

  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):

@thyname 

@kota1 : let’s be fair here, Sir Armir’s AP testing equipment alone is several times more expensive than your entire system. Everything sounds fabulous through it. Who listens to music nowadays. So 20th century. You measure. And enjoy the signal. Those graphs give you goosebumps 🤭 (I wanted to say “a hard on “ but I refrained)

Who listens to music these days?  Apparently not folks here who are having anxiety if their power cables are letting in enough air.  Or whether their systems are broken in. Rest of us enjoy our systems without such worries. 

As to graphs, the only person demanding graphs right now BTW is @kota1.  And OP made an attempt to get some for his cables but seems he didn't really want that either.

As to my system, it sounds great because that is what my ears tell me.  What business of yours to challenge my ears?  The main thing it is missing right now is air.  Lots of air.  As soon as one of you can convince me that one of your tweaks takes care of that business, that will be remedied as well.

Verified by perpetual blind tests I presume?

Somehow, posts like this make me wonder whether THE Amir account has been hacked by a 10-14 years old dude

 

@amir_asr I’m demanding graphs AND posting graphs, so where are yours? Let me know if you need help, NP. As for what your system sounds like that is up to you to know, I want to see what it looks like, please post, thanks.

Has the Kota stumped (embarrassed) you? I am detecting air from your direction, HOT air, lots and lots of hot air :).

If you don’t reply I gotta give the W to Audiogon Forum, we whipped the ASR champ in measurements!! Not bad. There is still another round, you just gotta answer the bell, ready, set, post the pics of your system, the components, and the FR measurements of your room...

Alternatively you can throw in the towel and it is Audiogon Forum 1, ASR 0 and we take the measurement/system title.

You still are a champ though... of air, HOT air, lots and lots of just hot air.
