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.

I don't know why you keep giving  yourself score of 1.  You have not post any measurements of your room as it sits now.  What you have in your profile is a fantasy.  It is NOT your room current room measurements.  You don't even know how to use the tool you have there.  Right now, I would give you score of -1. 

@amir_asr

Still waiting for you to post something, anything, that is why you have 0.

I gave you the benefit of the doubt you have a system so you do not get -1.

Can we get this game on, will you post your system profile, stop with the hot air already???

 

 

 

@prof you are a reader right? You troll through all these threads cause you have nothing better to do. 

How did you miss this? Amir tagged me. 

Now goodnight to you and charge those batteries on your trolling motor.

 

I do NOT refuse to accept the validity of blind testing equipment, cables or tweaks. 

 

That's good.

However, I am unable to do blind testing.  So, I rely on my hearing. 

Ok, that's fine.  As I've argued, most of us don't have the time or set up or inclination to do blind testing.  Buy what you want, for whatever reason.

But it gives me plenty of reason to maintain skepticism if you happen to make claims for hearing things that are technically improbable.  My skepticism shouldn't stop you from buying whatever you want of course...but if for instance you said an expensive digital cable made Big Differences in your system vs a functioning cheap digital cable, I'm quite aware it is likely sighted bias at work, unless it could be shown you or someone else could reliably identify these changes "without peeking." ;-)

Not too bad in my opinion.  I also listen to my friends who have superior acoustic listening/interpretation ability.  They pinpoint problems, one who has Asperger and audio sound is his superiority in life.  His hearing is like a computer.  I don't inform my two Golden Ear friends what I have done/doing.  They tell me what they are hearing and often, what corrections should be made.  Try topping that with Blind Testing by the usual crowd of audiophiles.  They have really taught me to hear/listen better.  My wife is so used to decades of my cable testing  for the manufacturer that she automatically is skeptical of the sound whether it meets with her approval or something less.  She said I have trained her to hear sound as well as music.  Before me, she was fine listening to a boombox and car radio.  

And the point that you don't want to acknowledge is that literally nothing you described in that paragraph protects you or anyone you mentioned from regular old perceptual biases in which you can hear things that aren't there.

Maybe that sounds dismissive to you.  But think of what your position will be when I might say "I don't hear a difference" with some gear change that you believe sounds different.  Your response will be dismissive of my hearing (or gear, or whatever), it won't act as any evidence against what you firmly believe because, as you've said, if you believe you heard it, it's true.

And, once again, I tend to buy gear essentially the same way you do, by listening to it, so we are not that far off as audiophiles.  I just try to maintain epistemic humility in the face of our perceptual fallibility, and acknowledge I could be wrong.

Now that you listed your creds I feel even better we are beating you at the

You can have a rematch anytime, with those creds you should do much better in the rematch, just answer the bell this time and post your system pics, components, and FR graph in your profile.

Otherwise that really long post of your impressive creds= just more hot air.

 

Yeesh.  This stuff is getting pretty childish.

Good sign this thread is in a death spiral. 

Time to abandon. 

See y'all....
