Frustrated with ASR's view on op-amps

What would you recommend for Tuvan Throat Singing?

Nothing that is on the market now. But I hear TI is tuning one of their op-amps based on this lovely track:

Why is it then, that folks here deny the benefits of op-amp rolling?
Click to expand...
There are many engineers on ASR who know how op-amps work, and most importantly, how the circuit around the op-amp controls the overall behaviour, to know that op-amp rolling is a bad idea.

If a circuit is designed around a Z1245, swapping in a B5634 will, at best have no benefit and most likely increase distortion, noise or instability, even if the B5634 specifications are better than the Z1245.

Your brain is lying to you. Every single time.

Maybe I'm just confused. Forgive me. Why does the Sparkos SS3602 sound better when everyone here says it's not supposed to? Isn't this an audio forum for hi-fi lovers who want to experience music? Why do lots of people like Sparkos op-amps and feel similarly about this? Are we all just experiencing some sort of illusion?
Click to expand...
Because you brain is fooling you. And yes, we are all experiencing some sort of illusion, because we all don't hear what our ears hear. We all hear what our brain makes of the signals our ears send us. Unfortunately our brains are about as reliable as politicians, Jeeps or a chocolate teapot.

We are basically just a brain in a vat that is connected to the outside world with the help of some sensors (your senses).
 
A bit off topic... but this is partly why I love this place, as in when rubbish is posted it's explained and negated quickly by multiple members.

Unlike those other forums where one makes an effort to post factual and helpful info, only to be shot down by subjective rants and often zero support from other members.

Nice one ASR.

How can we know that if you don't take measurements and show us the difference you're hearing?

People's ears lie to them all the time. Everyone. You, me, everybody. It's happened to me multiple times and those are just the few instances when I noticed the thing I was tweaking was actually turned off and caught them lying.

And this is when I was evaluating gear for my job. Listening skills at their peak.

So how am I supposed to trust a random person's ears more than my own... When I know better than to trust my own?

On one hand I have amir's tests showing no difference from swapping opamps. On the other I have your insistence that those measurements must be wrong because your ears don't lie to you? Put yourself in my shoes... Wouldn't you want something to hang your hat on here?

Taking into account ALL parameters and behaviour under different conditions, including EMI, the OPA627 remains a favorite to me. The genuine parts, not the fakes from strange sources.

But sadly those same opamps tuned for Tuvan male throat folk rock ballad will fail miserably with this Inuit female traditional throat singing. For "musicality" the chain has to be rebuilt completely. (Inuit music needs cryogenic treatment obviously.)

 
I went to roll some op-amps
My music to restore
Cause my big bands sounded small
And my jazz just wasn't jazzy anymore
And then I found the Sparkos
What a difference it made!
Big bands were bouncing off the scale
Jazz instruments did moan and wail
So excitedly I went on some forums
This miracle to explain
But was met with blind indifference
And lots of pure disdain
So dam all you objectivists
May your ears decay and rot
For you don't deserve to hear
The difference Sparkos brought!
 
We classicals have multiple mounted, controlled by 10-contact switches depending the piano or fff parts.
One should be in full alert, you don't play with things. :facepalm:

A longtime American friend is a Tuvan throat singer. He has won first in competitions in Tuva. Sadly travel has become difficult as Tuva is in Russia.

So the question is what kind of opamp is needed for Tuvan throat singing x country rock? That sounds like a project for Texas Instruments, the fusion opamp. We could have tuned-for-genre transformers, capacitors, and resistors, even different alloy wires. They do some throat singing at the end of this.


As many ASR participants know that the MP3 encoding format developed by Fraunhofer labs was optimized on a Suzanne Vega song. But MP3 is used on all genres.

The technology behind these three letters has become an inseparable part of our daily lives: in 2025, the file extension “.mp3” celebrates its 30th anniversary. This audio format laid the foundation for many more groundbreaking audio codecs made in Erlangen. An innovation that began at...
