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.

When I say there is a very significant difference, THERE IS!!!!!  

And that’s great. What the professor is saying is if you have nothing to back up what you are hearing, that’s just anecdotal, and you are making dubious unsubstantiated claims. If not simply hallucinating. You should refrain from posting such dubious claims in the Internet. You are risking some poor soul wasting hundreds of dollars of their hard earned money, blood sweat and tears, paying for enrichment of the evil audio manufacturer.

 

So please…. before you post anything, make sure you have proof. Either measurements, or blind tests certified by a third party independent panel. Preferably both. 

@thyname , your system looks great, is that a Mapleshade Samson rack you are using? I use their Bedrock speaker stands in the mancave and platform in my HT, Thanks

@prof You are such an expert in your opinion denying the plausibility that I hear great differences and can make an informed opinion of my own.

No, precisely the opposite. I recognize my limitations as NOT being an expert.

That’s why I value explanations by actual experts.

My whole approach starts from my (and humans in general) fallibility.

This seems hard to grasp for people who have trouble accepting their own experiences may be fallible.

 

 

When I say there is a very significant difference, THERE IS!!!!!

 

That is the confidence one sees from religious dogmatists. "I experienced it; nobody can tell me otherwise." By valuing your subjective opinion above any other evidence, you have made your belief unfalsifiable - no outside evidence to the contrary can budge you. I personally, along with plenty of others, prefer not to treat audio as if it were like religion.

So to provide a contrast: I really seem to perceive "obvious" differences when I’ve done some tube rolling. I’m fine to proceed on my experience. But I recognize I’m quite fallible and like anyone prone to listening biases. Therefore I would not simply declare "If I say there is an obvious difference THERE IS." I can acknowledge the point made by a skeptic that it could be some type of expectation effect or perceptual bias, rather than the sound changing audibly. I’m willing to be wrong, and it does not threaten my self-worth to admit my perception may be in error.

So, I guess that’s how we see things differently.

 

Blind ABX testing on these tweaks and I bet I couldn’t identify the differences. Change from six Pangea power cables to six Grover Huffman power cables in a high end/high cost system-OBVIOUSLY SUPERIOR!!!!!

 

So...do you mean you have reliably identified these power cables under blind test conditions?

@prof Yes that is why they reject Amir and I guess you too. Clearly you have nothing better to do. Yep troll on has to getting chilly on the lake. Bit windy today. 

Have a nice evening, hope you find something to do, listen to or read other than old old threads old chap.
