The Audio Science Review (ASR) approach to reviewing wines.


Imagine doing a wine review as follows - samples of wines are assessed by a reviewer who measures multiple variables including light transmission, specific gravity, residual sugar, salinity, boiling point etc.  These tests are repeated while playing test tones through the samples at different frequencies.

The results are compiled and the winner selected based on those measurements and the reviewer concludes that the other wines can't possibly be as good based on their measured results.  

At no point does the reviewer assess the bouquet of the wine nor taste it.  He relies on the science of measured results and not the decidedly unscientific subjective experience of smell and taste.

That is the ASR approach to audio - drinking Kool Aid, not wine.

LIKEWISE: no one can possibly know whether a new addition (ie: some kind of disc, crystal, fuse, interconnect, speaker cable, etc) will make a difference, in their system and room, with their media and to their ears, without trying them for themselves.

That’s simply false.

In many cases, we can absolutely know that there will be no audible difference made by some tweak, cable etc.

To think otherwise is basically scientific and engineering illiteracy.

What I meant there was that Amir Generally evaluates

Loudspeaker measurements based on the type of criteria derived from Blind loudspeaker testing,  Which are known to predict high preference scores.

And other words that is there “ Best practises” Reference in terms of speaker performance.  
 

If a speaker departs from this Amir Will try to Still describe the sound, 

And depending on how things work out, he might still give a speaker a pass.

But as Somebody who likes subjective reviews myself, I agree with you that

Amir’s Subjective portion is a bit too paltry for my taste.

 

I was also referencing that Amir when evaluating electronics tends to do so by referencing distortion levels generally known through testing to be in audible or not.

To quote from my previous post - "the speaker design - box vs planars vs horns vs OB".

You'll have no problem in any gathering of audiophiles finding people who prefer Magnepans or Klipschorns or Linkwitz over box speakers.  These speakers and many others differ in basic method of sound production, on- and off-axis frequency response, radiation patterns, impedance curves...  All of them have their fans.  They all differ quite noticeably in the way they sound.  Any set of measurements that would match well with one of these designs would likely produce poor results with the others.  Based on your argument, knowing Amir's specific measurement criteria should tell us what kind of speaker he prefers (subjectively).  You can't simply average all the speakers together into a Frankenspeaker.  So, has he ever divulged his reasoning for the measurements he makes and how he established their usefulness?

petaluman:

Amir has explained his choice of speaker measurement, the Spinorama, because of its closeness to the measurement in an anechoic chamber. There are explanations giving details of the setup on the ASR site.

He has posted his main system. He has used Revel Salon-2 floorstanders in that system.

I don't often read the site. There seem to be many there who prefer KEF monitors, and a fair number who like powered monitors from Genelec, Neumann and Dutch & Dutch.

 

And here’s another big problem with their methodology…THEY HAVE GOTTEN THE MEASUREMENTS WRONG. I’ve personally seen it, and frankly , it was embarrassing. If that’s your ONLY acceptable criteria and you screw it up…well what good are ANY of your conclusions and how can you be trusted?
