asr is good for things like power conditioners, cables, probably dacs too, maybe amps for some useful measures like power stability at different loads and such
IMO asr is least useful for speakers, which are far more personal
Did Amir Change Your Mind About Anything?
It’s easy to make snide remarks like “yes- I do the opposite of what he says.” And in some respects I agree, but if you do that, this is just going to be taken down. So I’m asking a serious question. Has ASR actually changed your opinion on anything? For me, I would say 2 things. I am a conservatory-trained musician and I do trust my ears. But ASR has reminded me to double check my opinions on a piece of gear to make sure I’m not imagining improvements. Not to get into double blind testing, but just to keep in mind that the brain can be fooled and make doubly sure that I’m hearing what I think I’m hearing. The second is power conditioning. I went from an expensive box back to my wiremold and I really don’t think I can hear a difference. I think that now that I understand the engineering behind AC use in an audio component, I am not convinced that power conditioning affects the component output. I think.
So please resist the urge to pile on. I think this could be a worthwhile discussion if that’s possible anymore. I hope it is.

@mahgister +1 There is one thing i like about Amir investigation... It debunk the myth and magic marketing LINEAR link between S.Q. and price tag...There is none... For example in dac... Dac is a mature technology, and we can now afford a very good one at relatively low price. |
this is correct and entirely consistent with my experience there are different mods on duty at any given time, tammy is the most thoughtful one, others will just delete stuff if requested without much if any thought -- all this is mostly just harmless drivel as they see it (a bunch of bored old men, sad nerds, and a few habitual troublemakers sparring) -- and they are largely right |
My point about electrical measures is simple : they are INFORMATION we must take as information, often very useful ... Amir give us much more information about the design of a component , then we can only thanks him for his " knowledge" ...
My other point is : Information is not knowledge... In audio as in any field the difference between information and knowledge is simple and explicitly given by the great mathematician of this century : Alexander Grothendieck : " an information may add something to us but did not change us, knowledge change us "... ( in his book " the Key of dreams") 😊 In audio, acoustic knowledge and basic psycho-acoustic experiments change us IMMEDIATELY, because they make us TOUCH and FEEL what is timbre for example or dynamic or transients or immersivenes, sound sources apparent localizations, or the listener envelopment and the sound source ratio etc , by experiments varying acoustic conditions in our room. These experiences not only add something as a mere information, as information about the design of a component can do, but when put in place in some order transform our hearing being completely and without coming back , we begin to be conscious of new aspect of us in relation to the sound and to the soundfield that we could not even imagine before it ... This why i said that we must learn how to listen, it is not given by purchasing 20 amplifiers or 30 headphones...It is information we gain by purchasing brand names not knowledge... We can buy information not knowledge... We can buy a book but we cannot buy the understanding experience of the book... This is why Acoustic is the heart of audio... Not electronic design by itself alone...Anyway revolution in electronic design also often comes from psycho-acoustic principles, facts or discoveries : Smyth realizer or Dr. Choueri BACCH filters among many others... I remember atmasphere explaing here 1 year ago very interestingly how his psycho-acoustic knowledge inspired him for the better design of his tube amplifiers for example...
