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.

Your information is useful,  but you cannot qualify all amplifier only on the specs measured... listening test arenecessary...

My information is routinely the only reliable data you have on performance of audio equipment.  The only thing outside of that is marking claims and buyer anecdotes.  Come back with such listening tests on all audio gear and I will stop measuring.

There is no mystery in what i said... this is evident

There is mystery when you state a theory you have believed with no evidence in reality.  You have not presented any data points related to performance of audio amplifiers.  You just want us to read a few lines of text written by a company designer.  So no, it is not evident in the least.  

All audio design is based on Fourier tools

Yours included and Van Maanen too...

But for Van Maanen some other aspects of his design are inspire4d by his hearing theory ideas... Then he used music real test  also and very importantly..

I thank you for your informative set of measures ffrom tghe beginning... Why ? because this useful...

But i disagree wi5th you vabout the importance of hearing theory and listening test...I disagree with the idea that we can predict more than the behaviour of the electronic compobnents but also their sound qualities... Sound qualities is a set...In this set each sonic character production cannot be predicted as human hearings will perceive it and judged it... 

In a word Fourier is reliaqble for circuit design not for predicting all aspects og hearin experience..

 
 

 

 

I wonder, if ASR website (Amir Science Review) was so popular, beating every single audio forum & site, including Stereophile, by multiple TIMES, why the owner of that site, the honorable Amir His Majesty, spend so much time here?

Because ASR is more than me: it includes tens of thousands of your fellow audiophiles who are discussing audio topics on their own without me.  I do my part to post my near daily reviews and folks go on discussing them and other topics of interest.  You can read my audio review from last night.  Or you can hang around here and continue to show interest in what we are discussing...

What? We design circuits based on knowledge of electronics, not Fourier "tools."  Fourier principles are used in such things as lossy audio compression but have no role in design of say, an analog amplifier.
