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.

 I can say it is a good thing that so many realise your site is a joke and that the number is increasing. 

Knock on wood, you are absolutely wrong on this.  ASR has had an incredible growth now being neck and neck for top audio site on the Internet.  Your fellow audiophiles see the value that the site brings.  Top people in the industry and luminaries in audio science and engineering are regular members and add incredible amount of value to the site.  And of course there are almost daily reviews of new products.  I tested a new Arendal speaker which I posted today that the company had sent me.

At the end of the day think what you are doing for your fellow audiophiles.  I am doing my part to bring people together and have robust discussion of audio science and engineering together with new data on daily basis.  If what floats your boat is rude arguments like this, then, yes, we are not for you.  Or your fellow posters with similar angst. 

I will take your hand ,Read me: measures in INNOVATIVE amplifier design are GUIDED by the designer EARS

His ears?  Why on earth should I trust his ears?  What training and qualifications does he have when it comes to his hearing?  Can he hear to 20 khz?  What level of noise and distortion can he hear?  Is he not influenced by wanting his own product to sound better?  

But let's say all of that is true.  Don't you think we should verify?  If a manufacturer says their amplifier has incredibly low noise, don't you think we can measure that?  What it he says it produces 200 watts; should we not verify that?  Let's look at an example in the form of Bob Carver.  Many people are his fans and think he has incredible abilities just like you are vouching for your hero designer:

Carver Crimson 275 Review (Tube Amp)

https://www.audiosciencereview.com/forum/index.php?threads/carver-crimson-275-review-tube-amp.29971/

It sadly is a noise and distortion factory:

But let's put that aside.  As the name indicates, the amplifier is supposed to produce 275 watts.  This is what it did instead:

Yup it blew its fuse after just producing 29 watts!!!  I replaced the fuse and tested again:

Even burst power to the right produces 75 watts, far short of of claimed 275 watts.

At 20 Hz, power drops to just 14 watts:

And look at the level of distortion, it is off the charts!

You see the power of measurements?  We are able to reliably and convincingly show that the famous Bob Carver who could do no wrong, indeed and done a lot wrong.  He had misled his customers by a mile.  And I say this sadly as someone who bought his receiver back in 1982!

I suggest you put less trust in people's claims and seek out independent analysis of audio technology.  This is what your fellow audiophiles are doing.  Resist the temptation to ignore science and engineering where it can generate so much useful information.  

Your site is well designed and Interesting Amir... I appreciate design and observations from various corners..

The fact that it draw many people talented in audio dont surprize me...

It does not means that your basic measuring and debunking philosophy is right...

In audio, in medecine as in politic, unanimous crowds are most of the times deluded...Ideology and technology are not science at all...

It is not simple matter to understand something... Especially basic audio debunking ... basic medecine debunking and basic geopolitic debunking ... Imagine psycho-acoustic debunking now ?

 

 

«My tool are better than your ears, it is simple , they measure distortion at level that you even never will dream to detect » -- Groucho Marx audio engineer 🤓

@amir_asr WTF are you even saying. Don't twist my words around. I didn't say that. No I dont agree. You never answered me. Why are those threads allowed but that one is closed? Show me where the answer is. You are delusional. 

You are always upside down...

You know nothing about psycho-physics it seems... or better said, you dont want to know... Because it will destuct your Fourier linear and time independant ideology...

I will take your hand ,Read me: measures in INNOVATIVE amplifier design are GUIDED by the designer EARS

His ears? Why on earth should I trust his ears? What training and qualifications does he have when it comes to his hearing? Can he hear to 20 khz?

The human ears dont listen abstract measures, but in the time domain the ears brain non linearly decode information so complex none of your tools can describe it...It is not measured in decibels, or in hertz... Etc... it is called Qualities... these qualities are investigated RIGOROUSLY in psycho-acoustic for example in the work of Oppenheim and Magnasco , you never commented about and i posted it 5 times..

We listen music, speech and natural sounds  and we RECOGNIZE them  we dont listen to  level of distortion  and we dont perceive it in isolation as your tools can in their linear and time independant way ... You listen to your tools first  , we listen music first ...

But read Hans Van Maanen... Debunk him... if you are able to debunk him... And i invite your audio disciples to read him too... Explain to me where he is wrong...Go and do it...

His work in speakers and amplifier design called " temporal coherence" because it is founded on psycho-acoustic hearing basics... Not on Fourier linear and time independant tools as your debunking tools ... The tools you use to debunk... He use other tools measuring scheme to DESIGN his own works in amplification and speakers after  studying psycho-acoustic real discoveries about hearing..

You may convince yourself that using these linear time independant tools will give you hints about "transparency" as you call your fetish acoustic concept...But timbre accuracy and musical sense live in the time domain and are more fundamental because they are determined more by the ears acoustic than by electronic chip well "measured" by you and well scored by you  ... Measuring Dac is one thing... Measuring amplifier another things, and measuring speakers another things... as you know already for sure ... BUT measuring all that at the end is BY THE EARS/BRAIN not by Tools working linearly in the time independant domain...designing  business is not debunking business at all ....
