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.

@axo1989 , whatever floats your boat is cool, I agree. But you shouldn't cast spitballs at other peoples boats when yours has holes in it, right? 

@amir_asr , why not join us in the thread on frequency response to discuss?

Well, one of the "different choices" I'd make is to be less of a [redacted] on the interwebs. Whether I succeed is another matter. 🙂

@holmz Guess that is why you keep coming back eh.

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

We could all pause and take a good look at ourselves occasionally.
 

One could argue that sticking to the thread topic is not trolling.
If you want to try that sometime, then I am sure few would complain… @jerryg123

@prof I am not an "expert" but it only takes a layman to hear SIGNIFICANT DIFFERENCES.  Are you deaf (or rather taste depleted that you can't tell salt from sugar)?  I have many friends, some who are experts in sound who do this for a living and very successfully for some of them, others as a serious hobby.  THEY DON'T MEASURE EVERY DIFFERENCE, it's a waste of time if the difference is significant, for better or worse.  If it is just different but neither better or worse, they just say whatever one prefers.  Look at the construction of a Pangea $65 power cable and a Grover Huffman $350 or $750 power cable.  HUGE difference.   Patent issued for the Grover Huffman cable.  I am not stating that it is the best cable in the world or for any system over other cables (only the ones I've compared them to).  I KNOW from several systems which switched out those cables that those equipment owners are delighted to have greatly upgraded their audio systems at a reasonable cost.  You don't have to believe me, that's your prerogative.  However, no one will be wasting their $100s on inferior garbage cables using superior cables. 

Again, maybe all those above posts don't believe cables make any sonic difference.  Then don't read my analysis as you will be sorely disappointed.  Go back to your "snake oil" forums on ASR.   

Talk about wasting $10,000s and more on cables would be using the very inferior design (electrically provable yet patented) High Fidelity cables.  Some people love them.  Most who have heard them don't, including my personal experience with a wealthy analog audiophile who dumped them when he knew he was experiencing shrill and thin sound (he came over to my home and my relatively puny system had his jaw drop versus his $1 million system.   Luckily for the majority of audiophiles, High Fidelity cables corporation is defunct saving the public from bad and very expensive cables.  Contrarywise, I have never heard a less than excellent system using Masterbuilt cables despite their equally high price when used with Von Schweikert speakers.  I have no idea about their construction or test measurements.  They do work magnificently on those speakers though and in those associated systems.  And if you don't believe me on this, how about the 40 or 50 reviewers of the Von Schweikert speaker demonstrations over the past few years which had reportedly had them transfixed, spending hours past midnight and earning among the most awards as best in show.  I doubt that so many people are being mislead.  Maybe Masterbuilt cables aren't the best or best for their cost but they certainly earn credibility in the best show systems in audio.
