That is also correct and includes another level. The memory (stored as an emotion) and a haptic, sensual element when handling a record player. You look at the rotating and playing record almost in love.

This only goes to show how comprehensive a comparison is when it comes to the audio comparison of amp-concepts: the prerequisites for an assessable audio comparison must be taken into account. And most people don't even know where their speakers are positioned because they don't know, for example, that most multi-channel signals are on all the channels involved: Mono;-) So how do we want to assess amplifier concepts in terms of sound without profound and comprehensive knowledge;-?
I remind you of this homework - one - of the few - door into understanding electronics and audio(-:
Homework, because this will be your practical experience that nobody will take away from you 😉
Agreed. As I wrote, today, the physical signal transfer-chain parameters are, relatively, easily made to exceed human hearing acuity.
Also, agree. The complex room-speaker-psychoacoustic interaction presents the greatest area for subjective realism improvement for in-home music reproduction. Of these, perhaps, the most problematic to effectively address may be the room. Certain speaker design can much mitigate the inevitable presence of the room via controlled directivity.

A general side note:
For almost 40 years I have been comparing the circuits and published measurement results of various power amplifiers in the DIY sector, but also in the commercial professional sector.
To this day, I have not been able to identify any significant improvements, nothing that would really make a difference in daily operation.
But one point, which only contains the recipe - the guidelines of Douglas Self's Blameless concept, which are not really new either, impresses me in its simplicity and incorruptibility.
Can we find a catch on a ReVox B750, for example? Or claim that the Millennium Crescendo (2001) is even a bit better than the 1981 Crescendo? Published in Elektor magazine. No!

The Revox B750 had some room for improvement, while the 1981 Crescendo would had greatly benefited from a revision,
as it is it s a recipe for oscillations because the designer misunderstood his own design and chased the lower possible THD.
As for the Revox B750 i had the chance to make a listening experience in an audio fair when i was 15, the technician kindly made
me a demo with several speakers in a comparison with a Tanberg 2040, of course the higher power of the Revox made a difference in sound quality perception.

Audio amplification is a solved problem.
Totally agreed. You may study the work of Bob Cordell and Douglas Self as well as Bruno Putzeys - and then there is very little left to say.
This is what makes debating the details of the 1000th re-invention of the class AB amplifier so utterly boring.

As are passenger jets? Safer than cars, after all. One might say passenger cars are a solved problem, car/truck motors are a solved problem, etc. Household lighting is a solved problem, beds that don't sag are a solved problem, TVs with great color are a solved problem.
Depends a lot on how someone wants to define "solved" in a particular case.

"Mature" is probably a better word than "solved" to describe the state of audio amp design.
Still seems kind of depressing to frame the situation as the only thing left to do is to bring down the cost. Guess we could say the same about private jets?
Anyway, would anyone like to say where there is still work to be done in audio that isn't already fully written down in "how to" books?

Yeah, there is that. But isn't there still some more that's under our control as designers/builders yet isn't in a Cordell/Self/Putzeys/etc., "how to" publication?
They are not a good exemple, they are THE exemple, all the rest has been solved to some extent, they are the last
stronghold of huge non linearities, as if we were using amps with 3-5% THD + IMD along with erratic bandwiths
connected to perfectly linear speakers, then we wouldnt try to improve the speakers as a cure, or would we..?.
Not really. Speakers have been solved/matured too. Mainly the price needs to come down. https://www.soundlabspeakers.com/
Same for dacs. Mola dacs by Bruno Putzeys cost something over $10,000 for two channels. Do they sound better than a Topping? Of course they do. An AP just doesn't measure everything that matters. It only measures things most people here tend to be familiar with, and too many of those people think what they are familiar with is all there is.

The maturity you re talking about is us accepting them as they are, that is, highly non linear because we all know that there s
no cure to this problem with the existent technology.
As for 10 000$ DACs sounding better that s an impossibility since you ll listen to the result with speakers that have 3-5%
THD + IMD, they will sound no better than DACs that cost 1/20 this amount, or are you saying that this 10k $ DAC magically
reduce the speakers non linearities.?.
