Does Op-amp Rolling Work?

[MAB]

I am leaving this thread but I will say biology>rest of you

Better to either study the actual contents of the forum. or just leave the forum. Lot's of other places on the internet will validate your views, if not your ego.

. I apply logic and say human brain (most complex structure in universe that we know of) is better than a simple measuring device, no matter how accurate.

How fast is your car going without a simple measuring device?
What time is it without a simple measuring device?
How cold is it in winter without a simple measuring device?
How heavy is that rock without a simple measuring device?
Try keeping track of your blood pressure without a simple measuring device.
Try keeping track of your electricity usage this month without a simple measuring device.

The human brain is complex, all right. You're correct about that. But it was developed over time for our survival, not to measure things or processes. For measurements, we have devices ... instruments ... standards and comparisons ... and these give us data that the brain cannot.

If you don't believe me, tell me the diameter of a strand of your hair without a simple measuring device.

Then if should be trivial to produce some evidence?

I cannot give you evidence sorry

dude i hear difference between op 1656 and 1612, but this is wrong site for me, my ears that matter to me.

To be able to differentiate a qualitative difference between sound sources when the sound is only very slightly a tiny tiny bit different but there is a delay between the sound being present and then existing again is next to impossible. Then consider a case where the sound is shut off for minutes, hours or days and that difference in sound now becomes impossible to differentiate qualitatively. To listen to a quality OP amp that mostly sounds like any other quality OP amp, then swap out to a different quality OP amp and expect the human brain to remember the old OP amp and compare that to the new OP amp is a fantasy. There is no basis in reality for this fantasy.

I understand that and believe you. There are obvious reasons for that too and these are brain related.
What 'ASR members' ask is evidence other than anecdotal.
This can be done using blind level matched testing and if you need to prove that you can it must be witnessed by someone with knowledge and integrity.

So ... be happy you can hear it but without any evidence other than your blue eyes (and brain) you are not going to convince the 'cloth-eared skeptics'.
There are literally hundreds if not thousands of people that also hear perceive differences.
The problem so far is that they have not been able to show this ability in lab conditions.

Queue fancy image of human biases…:

All of this is done by your brain, due to all of that evolution you were talking about.

 

[pma]

You will not persuade the believers.

 

[Cbdb2]

Human hearing relies on insanely complex biological and possibly quantum processes shaped by millions of years of evolution. No electronic measurement—no matter how advanced—can fully capture that.

We are talking about voltages not hearing and my $20 multimeter is orders of magnitude better at measureing voltages than your ears.

 

[MaxwellsEq]

But what we hear is way more sophisticated than a $$ measuring device can show us.

Pay very careful attention to what I am about to explain to you.

The recording you are listening to IS A MEASUREMENT! It's a stored record of the electrical measurement of pressure changes in a microphone capsule.

I think you just did.

 

[Joe Smith]

It's so relaxing to get to my age and know that none of this needs debating anymore...with a 12,000hz top end and mild tinnitus, I don't need to be concerned with op-amp differences anymore...and happy to play at the 98% level of music reproduction and not worry about that last 2%...

 

[testp]

just observing, AI response was more like: machine is precise, but human brain adds meaning to things.

(machine) and (human) "do" different things "best" is what i interpret from it, nothing more.

 

[oleg87]

Well my point is we still do not know how the human brain works. You might say human hearing is limited because of limited frequency sensitiveness. But what we hear is way more sophisticated than a $$ measuring device can show us. I apply logic and say human brain (most complex structure in universe that we know of) is better than a simple measuring device, no matter how accurate.

[theREALdotnet]

All he had to do was quote Floyd Toole: "two ears and a brain are far more analytical than an omnidirectional microphone and an analyzer."
(section 18.2.1)

 

[RexrothPigeon]

Me personally, I like to believe that 3.5 billion years of evolution is better at some things than a $200,000 analyzer.

Of course, but not any of the things op-amp rolling purports to accomplish

 

[RexrothPigeon]

This is precisely why logic is so limited and empiricism trumps all. Reminds me of Aristotle, who, using logic, determined that because women are smaller than men, they therefore have fewer teeth.

When in reality it is men who have fewer teeth on average, because, due their biological disposition, they tend to get into fist fights more often.

Ah yes, the apparently ancient phenomenon yours truly calls "runaway inference."

How exactly have you done your testing to come to this conclusion? What is your testing setup?

 

[JSmith]

I cannot give you evidence sorry

Would you go to a Doctor, question everything they say... even though they studied for years, did the hard yards in practical, ran a successful practice for 20 years... then say they are incorrect, when there is decades of evidence to the contrary? Then carry on with a bunch of non-medical nonsense and when challenged by the Doctor, all you have is "I cannot give you evidence, sorry"? Maybe you drank the bleach...

Stop the trolling, it's getting tiresome.
