Tomorrows landfill and a waste of the planets resources. This opinion is gaining ground fast.
It doesn't work like that. You have to change something.
However if are not in the same mood from one day to another you might listen to it differently.....
The mathematical basis is simply not known because one should know exactly how the human being and his brain work. It is a subject of research but the status is rather primitive in comparison to other sciences. However it is really difficult to imagine how to describe emotions by means of mathematical tools.....

None!
No but that's not the point. Recording music doesn't mean that "you have to trust" a microphone. You can listen listen to the recording to make decisions....
The microphone is just a mean not the reference!
Vinyl playback introduces quite a lot of harmonic distortions.
These result in a measurable lower dynamic range compared to the original. This a.o. means that lower level signals are increased in level. We perceive this as more low level detail.
An other result of these added harmonics is and increase in perceived loudness of the signal. Simple tests verifies this: Listen to a sine wave and a square wave of the same measured level. The perceived loudness of the square wave is a lot higher. Or if you have a synthesizer just turn up the cutoff of the low pass filter and the perceived loudness goes up as the cutoff goes up. Link here: Lowpass Filter Shootout (simple sweeps) | Matttech Modular Demos
So vinyl playback creates the illusion of more low level detail and more loudness/higher dynamic range. But it is an effect.
Digital playback is much more transparent to the source.
See post 2884 of this thread on page 300 where a consumer level showed no audible degradation when inserted into a "relatively high end " LP system.

30 years ago people were thinking the same! The reality is different....😀
I think one should look at his life first and make decisions accordingly.
No it is not phylosophy it is just a REAL system that you can only dream and not just because of the cost because you can get close without spending a fortune.
Maybe you have problems with this....as already told I also have CD's and use them.

All good points, but that only reinforces the need for some clear goals before you start your design process. I mean, you can't get around extensive testing on the bench if you want to design an amp that is claimed to deliver 100W/8ohms with damping factor of 100 and THD below 0.01% at all levels and frequncies. There is still a need to confirm that your amp does it before unleashing it on the public.
Then if your marketing guy wants beewax caps in there because the reveiwer will publish inside pictures in the glossy and beewax caps look great & will sell, all fine and dandy but at the very least you'll want to verify that the beewax doesn't mess up your circuit becaus it has more parasitics than a well-engineered standard cap.
I still maintain that it is better to do the design stuff as much without emotions as possible.
But when listening for pleasure you can cry all you want; I do, once in a while 😉

Ohh but I can. Look at neckties - about as non-functional as it comes. Yet, lots of people make lots of money selling very expensive neckties!
Audio is a fashion industry, after all!

This is pretty much hogwash. I do not need to understand the mathematical basis for music to sit in the Amsterdam Concertgebouw and enjoy a great opera.
Likewise, if I faithfully reproduce the air vibrations from the Concertgebouw performance in my living room, I can again enjoy it. All without knowing the 'mathematics of music' - and a lot of other things I have no idea about and are equally irrelevant.
You have a wrong perception of these issues. You are desperately trying to find arguments to support your wrong ideas, but because of them being wrong, you are not succeeding. Doomed from the start - you should have cut your losses earlier, too late now without loosing face...

I totally agree, but that just begs the question of how you figure out what the goals should be! That is the really interesting part of audio IMO. 🙂
I personally agree with you and Douglas Self, the hi-fi system is for reproducing the original recording as accurately as possible. Modifying the recording to make it sound better is the job of the recording engineers. (And the speaker designer 🙂 )
Yes indeed and it's something an engineer cannot do by himself. He needs other disciplines to support that if you want more than just fringe success in the marketplace.
It was a general consideration about something not necessarily related to music. More likely is nonsense and I agree with you but in general I am not God and you can never say never. It would the end of research....
Yes you know me.....
Do you want to bet? I am not joking. Then we will see whether I lose my face or you lose your money. Every time I ask this question people run away!
Why? The only response I can give to myself is that people reacting like you are frustrated. Just good for typing behind a screen.
