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.

Someone’s a little butt-hurt.

Isn’t this the review where you hook the $400 power cable into the $500 DAC, listen through headphones, measure the heck out of it, and then claim it makes no difference?

 

Then you got called out on GR’s channel (in the end......by name).

You’re a tool, man. The more you post on here, the less my opinion of you. You’re not a professional, you’re a wannabe. Try not to be butt-hurt, it’s unprofessional. "Desperately clinging to the straws of credibility."

 

You’re certainly entitled to hook up and measure whatever you want, and report whatever "findings" you come up with.

I just hope people can see through it.

@amir_asr, any chance that Ranch invite to Sisters OR. happened some years ago. In particular, Steve Nugent of Empirical Audio and his updated Synchro-Mesh re-clocker powered with his Dynamo LPS, under his measurement conditions. Clearly if one attended, that would’ve come with the package deal. A Overdrive SX DAC, Off-Ramp 6 or Interchange Renderer, and Final Drives listen. Ring a bell?

Another point of view on th GR Research power cord from our member @abdodson 

I put the first one on the amp. It replaced a similarly priced well regarded cable. No contest. More air, better separation, more dynamic. Across the board better, significantly better. I quickly ordered two more, wondering how they would sound on my DAC (Lampizator Atlantic TRP) and CD transport (Sim Moon 260D). On the DAC the cable being replaced is almost 3 times the cost of the GR Research cable. Again, no contest at all. The GR Research cable wins hands down in every respect (the one caveat here, and I hesitate to mention it, is the soundstage is still a little messy. But this is with almost 100% certainty a break-in issue).

As a beta tester for GroverHuffman cables, we have tried half a dozen Furutech A/C & IEC plugs over several decades.  We found that the more expensive ends tended to be brighter sounder with higher resolution and the lower end plugs maintain more body.  After trying many plugs from other companies, Grover found a Taiwan all copper plug that had good grip, excellent build qualities, a neutral sound resulting in great body and adequately high resolution to use with his power cables.  They cost less but sound (or lack of sound) great.

"Then you got called out on GR’s channel (in the end......by name)."

Of course he does.  I point out when that his products don't perform with an array of tests.  Such as that cable that barely functions as a power cable.  While I have praised some of his products, he does produce some really, really bad ones:

 

He relies on his viewers knowing less about audio than him. Don't be that viewer....
