vzaichenko,
In an inconsistent formal system comprising multilayered abstraction, full of logical, syntactical and semantical paradoxes, it can be tricky to decide off the cuff or maybe even when you are focused, what is nonsense and what is not. Truth is elusive. Check it out for yourself from trusted sources if you do think it's worth the hassle. I doubt you do. As a matter of fact, I rather dissuade you from udertaking that epic adventure.
Which statement do you find most disturbing?

Parallel universe is certainly the most likely explanation.
Can you show me where I wrote Rg||Rf=1k and Rf=1k please ?
Anyway, as Scott says, there is no Rg. Rf = 1k , closed loop gain is ~1.
Yes of course that is true, but I would never recommend doing that. It will destroy the performance and add noise.
I see no technical reasons why a CFA would be better than a properly designed VFA when it comes to sound reproduction. Personally I prefer H-bridge VFA for technical reasons.
On the other hand I see some reasons that would make a properly designed VFA better than a CFA, but that is only technical reasons and not subjective "sound quality" reasons.
I'm not afraid of PIM or TIM and if one think that a flat Aol up to several kHz is important one can always use the Otala way.
When it comes to hand waving arguments, I'll leave it to others.
Sorry, since I have no idea what you are talking about, and don’t feel like further investing time and effort to figure it out, I give up. Good luck!
OK.
But you could at least recognize, by intellectual honesty, that I never wrote Rg||Rf=1k and Rf=1k, and you made an error on this point.
Poetry is not allowed in this forum, sorry.
Wrong hemisphere...
Cheers,

PS: have you noticed that our education system stimulates only one of them hemispheres?
Thanks.
This make your position on bidirectional or unidirectional COD vs symetric or asymmetric CFA topology clearer.
Just use the test as it is meant to be.
Insert a circuit without any form of external feedback or resistors between the inputs.
All and nothing else it will tell you, whether this circuit has a CFA or a VFA topology with a high probability.
See below the outcome of a test with a single transistor. Has it a CFA topology in this setting ? The test confirms this with a yes.
Is therefore every transistor in every application a CFA ? Of course not.

Science as subsitute for religion.
The logical, conceptual, procedural and number system problems involved in Mathematical Analysis are huge and plenty. The unpalatable discoveries made in the twentieth century have generated tons of literature, but not harmed the authenticity and credibility of Mathematical Analysis. Mathematical Realism established in science, which is not a theory but a religious doctrine, holds the indispensability of numbers to true knowledge and a reliable model of reality. Mathematical Realism adds a miraculous semantic dimension to the scientific worldview, incorporating the numinous believe that numbers have a concrete mind-independent existence with perceptible spatiotemporal properties that anyone can aquire knowledge of without smoking anything. Like every religion of dignity, Physical Theory too has a poetic creation myth, depicting a dramatic moment of birth out of the infinite void of nothingness - some abstract notions gracefully converted to matter - and an ever since growing bubble, all duly calculated and validated in accord with the global cosmological constants, the dark energy parameter, and spiced up with some superimposed Hamiltonian stationary zero saddle point vacuum energy eigenvalues. Theories not formulated mathematically allowing easy computational solutions deserve no attention.

I mostly agree with that, but would like to add that operators on infinite-dimensional Hilbert spaces need not have eigenvalues. However, all routine quantum mechanical calculations can be done using the physical formulation which means that the audibility of room resonances is basically an Hermitian function.

I think what this thread needs most, and you'd all benefit personally from, is "MORE COWBELL!"

What are the approachs you think to be the most convincing (with links, please).
