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.

Once again, JA makes it clear its a nearfield measurement without correction, it's up to the viewer to read his speaker measurements section.

He doesn't make it clear.  Most people will have no idea what I quoted means.  They see a graph and run home thinking the designer screwed up.

NFS is a great tool, but certainly not mandatory for knowledgeable designers.

Go and ask Ascend.  Since purchasing NFS, post my measurements of their speaker with the same showing serious issues, their design has been hugely transformed.  They can get full 3-D radiation of a speaker in 3 hours and iterate on the design on daily basis.  In contrast, garage show operations like yours will make a crude gated measurement or two and call it the day.  

Yes, if you spend the time and energy as you linked to in ASR link, you can get proper measurements.  But that is not what JA is doing.  And certainly not what you are doing on daily basis.

So yes, what else is new.  Garage shop operation sells speakers for $15,000 but works hard to say a) you don't need to see any measurements of said speakers and b) incorrect measurements claimed to be correct. 

@amir_asr   You have said that you have been insulted here by myself and others, yet you have the temerity to post what you just did about the experience level of all audiophiles. You put all of the group into one basket, that of being clumsy and ignorant consumers..and therefore easy marks. Not ok in my books.

What did you get insulted by and who says "ALL" audiophiles are alike?  Countless audiophiles are on ASR following and believing in audio science and engineering.

I am talking about people we both know that change a screw in an AC outlet and say another veil was lifted from the sound.  Maybe it was, maybe it wasn't.  We would only know if he did a simple blind test of that.  He didn't and observing that doesn't make what I said an insult.

Believe or not, there are folk here who have extensive experience and are not just shopping with their eyes and attracted to the highest price anything.

Ah the self-serving "experience" bit.  That much abused word.  This is how such experienced listeners as audio reviewers did in test speakers;

You want to explain to me why Audio Reviewers were producing such unreliable listening test results when evaluating speakers in a blind test?  That they could not repeat their own outcome when comparing speakers?  Experience didn't help them.  Nor did it help audio retailers and marketing/sales.

Proper "experience" was in the form of trained listeners.  They followed the proper path to get trained and their skill was proven in such tests. 

So please, don't use these cliches with me.  The whole purpose of my post was that I know what you speak of.  Experience....

 

Amir said and even proudly bolded it...

"I don't trust any subjective review that is not grounded on measurements."

 

This says it all about your mindset.  And all one needs to know about your site.  You should put this in bold letters on the home page.  

 Your subjective review is worthless since you have predetermined how it SHOULD sound based on some numbers.   You've guaranteed to have a biased opinion.  It's worse than any placebo effect from the appearance of the speaker.  Good experiment in psycoacoustics though. 

 

As far as the LRS, no one needs the numbers to know the sub bass isn't there or that they are beamy.  Anyone that has ever heard them knows that.  They heard it.  

So to reiterate....  Measurements are next to useless to determine how a certain  HI FI product sounds.  They can actually mislead and knowing measurements beforehand guarantees the placebo effect which might help cheap DACs sound "better".

 

Hey wow!  Amir got a chart for everything!  They are all totally unbiased I’m sure. 😉
