We could debate this till the cows come home, but I stand by what I said. PCM as a technology for digital recording was first invented by Denon, whose early recordings were released on the first compact discs that I bought in the early 1980s. I am not talking about academic papers on PCM.

No problem, I am not debating. You have provided the link that says you are not right ... We can return to listening to the nice recordings you are suggesting!
" In 1967, the first PCM recorder was developed by NHK's research facilities in Japan.[21] The 30 kHz 12-bit device used a compander (similar to DBX Noise Reduction) to extend the dynamic range, and stored the signals on a video tape recorder. In 1969, NHK expanded the system's capabilities to 2-channel stereo and 32 kHz 13-bit resolution. In January 1971, using NHK's PCM recording system, engineers at Denon recorded the first commercial digital recordings.[note 1][21]
In 1972, Denon unveiled the first 8-channel digital recorder, the DN-023R, which used a 4-head open reel broadcast video tape recorder to record in 47.25 kHz, 13-bit PCM audio"
Huh? Wasn't posting about social context but to your comment, nothing makes any sense anymore. We live in an upside-down world and I don't believe anything would suprise me at this point.

Ah no, that is not “innovation in the auto industry over the last 10 years”.
The antilock braking systems were invented for the aircraft/aerospace and rail, a hundred years ago.
It may have been considered a quantum leap 100 years ago, and coincidentally actual “quantum mechanics” is also 100 years old this year.
Anti-lock braking system - Wikipedia
The Citroen DS had the turning headlights over 60 years ago, and they were banned as being unsafe in the US.
The only thing that is a quantum leap of auto manufacturers and the government, was collusion in defining them as unsafe.
The guitar community is constantly moving gear around. I play bass and i've bought and sold about 5 basses in 5 years. I've kept the two i have now for the last 2 years. Also bought and sold heaps of effect pedals in that time.
PCM is a way of transmitting and storing analog information in digital form. As such it is used for recording.
The reverse process is called Pulse Code Demodulation (PCDM) - it converts the digital information in analog signals and is used for playback.
In fact , we often simply refer to ADCs and DACs and forget the academics of it ...
I think this is a big assumption around which we have no statistical evidence. I bet the box swappers tend to be the most vocal, because they have the most stuff to talk about.
I am not at all confident it reflects the median audiophile.

The very first digital "of sorts" recording and digital system is actually
The Mayan Khipu... knots on a string method.
Also used to jot down songs...
Not really decoded yet. But quite simpl a Multi-nary (word pun on binary) way of storing information.
Hence in essence - Digital
On the note of digital. First occurance...
You are all wrong.
The year was 1926. Inventor: Western Electric...
ge?
Google it. The patent is from 1903...
Paper strip running at a set speed, punctured to a rhythm.
That sounds like laser/cd medium. but more stone age...
Duh huuu!!!That is 5 bits people... 1926...IE 4000hz recording span..

Or has the best marketing team shilling for them.
There is a lot of talk about shills but I have never heard of or seen anyone getting paid and feel this talk of shills is largely a myth started by people who want to denigrate a particular brand they don't favor. I believe it is also rooted in times at jealousy directed at companies that have done well by working hard and being innovative.
Ultimately, I think the best products stand the test of time in our hobby. Following a product introduction more and more people eventually get to hear the product for themselves and decide. Word gets out.
Yes, there are great examples of pre-digital electronics digital conversion. The first nuclear spectra were obtained with an electromechanical ‘kick-sorter’ using with small metal balls, similar to a pin ball machine. The spring was pushed with a force proportional to the energy of the particle.
Since 1950 an ADC is used to do it.
Sweet, but actually ..
it is since 1853.,,.
They could ADC in 1853,,, but DA in 1926..theoretically in 1903.
I will elaborate…
They could ‘record’ but at replay it was not ‘intellible’ meaning. Not Good enough.
But in 1926 they recorded and it was played back as understandable Word. And the person was recognicable… so Fidelity was now possible…
Quiz a feat. Actually.
It was discovered then .. in 1926 that the needed frequency range was from 100hz to 4300 hz to assure that a person could be identified in the recording…
IF we look at wax cylinders at the time the frequency span was 250hz to 2600hz…
So it was a paradimgal shift…
On a side note… first vinyl was ca 1930…for sale in a store.
Or 1898 (shellac - same wax as cylinders but now as a ‘disc) they discovered the method..
developed it and started to experiment

As far as I see it no one claims he is 100% independent and fully unbiased in the high-end business. People assume their preferences and friendships, I can't see how this can be considered shilling.
Yes, some people assume denigrating particular brands and part of the industry as a crusade. We got used to it.
Very true. Sometimes it is unfair to recent and excellent products, but many consumers want something with an history.
Sell overpriced Hi-Fi equipment with hyperbole ! Preferably brands you somenhow represent. The higher the price, the better. A 2 million dollar speaker will soon be here !
No point of diminishing return i Hi-Fi, just pile a extra million on that sales price, we have to pay for marketing. I commend you for being so transparet.

A few observations:
1. I don't represent any brands.
2. I present a good argument on the Law of Diminishing Returns.
3. I have frequently stated that there are many examples where lower-priced gear outperforms.
4. I said in my TAS video that I welcomed a $2 million speaker as I think it could set new playback quality and it would be fun to hear that. Would you turn down a ride in a Porsche Cup car? I didn't.
5. I get enthusiastic about gear that performs well.
6. What is over-priced? How do you judge that?
It is curious that a few speakers on the market before 2010 had a cost around $1million. This only become a concern for some people loving the diminishing returns dogma after a manufacturer make one approaching this price that successfully sold 70 pairs ...
Currently we have more than fifteen speakers costing over $800k.

What makes you think so many audiophiles change gear with great regularity? I know plenty who don't. Maybe those who frequent forums such as this? I personally don't. It's a mere matter of finding something one really likes (and can afford). Of course there are people who are constantly on the lookout, eternally dissatisfied, but it's always seemed to me this has nothing to do with being a music lover, those people tend to be the exact same in other aspects of life. What I do consider an essential part of happiness is curiosity and the ability to learn. I do love to spend time with audiophile buddies, go to shows, hear new stuff. Having said that, at the end of the day, the basis of my buying decisions is not an itch, but relevance. Something would have to make me listen to music (and I mean attentively, I try to avoid background noise altogether) even more than the 20-25 hours per week I manage to get in, or with even less listening fatigue (that would be tough, even when I listen for 7 hours straight, those tend to be the days or nights into the wee hours when I'm tempted to put on yet another album). Are all differences we hear improvements? Relevant improvements? Much of what I'm hearing seem like side steps to me. To me, what you're touching on IS what I consider relevant and an improvement: what one enjoys on a daily basis, holds on to, and would not want to change is the very definition of "better".
Greetings from Switzerland, David.
