My intuition is amazing... or are you and I telepathically connected somehow!?
When I started this topic a while ago, I had mental images and you in the foreground, your opinion and reactions!
I thought of putting something like: "Analog vs Digital, for my dear friend Paul" in the title of the topic... but I gave up anyway.
It would be too pretentious.
But I swear to God; I was 101% sure that you would be the fastest and the first to comment on my first post!
Paul... although you will laugh at it, there is some truth to the story in the video.

... I think the drugs helped alot too.
The ( analogue ) tape machines they used in recording studios were a bit better than your home reel to reel though.
Like the Studer A800 24 track analogue tape recorder circa 1978.

Certainly yes.
I worked professionally in the main state television in the period from 1999-2004 as an "editor", the first generation that started doing non-linear editing on digital machines.
Then I had the opportunity to see live some of the highest quality "reel" machines that were used up to that time.
For many years I dealt with electronics for musicians. Professional musicians brought their instruments to me for service.
That's when I felt for the first time what human prejudice means, like: "but that detector previously successfully detected a small gold coin at 1.2 meters! (with a 20cm coil)..."
The most striking example is that of my very good friend, a guitarist, and his "Messa Boogie" combo amp (I don't remember the model, I think it was a five).
The amplifier was 2 years old. Hybrid, tubes combined with digital technology.
One morning a friend got up and turned on the amplifier, and from that moment on: "...I hear a thin, quiet metallic shrill sound, which was not there before... so the amplifier has broken down, help!"
At that time I still didn't have a serious ear injury, I had excellent hearing... For 4-5 days I "tortured" the amplifier in every possible way and I didn't manage to hear anything unusual. In my opinion, the amplifier sounded perfect!
However, the friend still heard a "glitch" in the sound.
Ok, then one day I organized a "consilium" made up of several professional musicians and several fellow repairmen, to examine the problem together.
After a few hours, the conclusion of the "consilium" is that everything is fine with the amplifier.
Our joint conclusion did not satisfy the owner. He took the amplifier to another repairer in another city.
But ... Serbia is small, we all know each other professionally... news spreads very quickly...
Epilogue: after several months of carrying amplifier all over Serbia to various experts; my friend, all unhappy and dissatisfied, sold the amplifier to the first buyer... at a discounted price.
"...something still sounds wrong, it doesn't work as it used to..."
"...my White's detected a small gold coin 1.2 meters deep in the ground, now no more than 25cm in the air... something is wrong..."
Ok, funny, but that's not the point of the thread. I am also one of those (in my right mind) who advocate the theory that analog technology is still better heard than digital.
I don't do drugs... although in recent months I've been taking painkillers uncontrollably because of the torn muscle fibers in my arm... so your theory about hallucinogenicity falls away.

As an audiophile, I've always loved cutting-edge technology.
The other day I accidentally received a Kenwood radio receiver, model KT-6040, as a gift.
Older production.
What can I say? Perfection!
I have a lot of radios in the house.
But this model catches the most stations, has the warmest sound, I've never had anything better in my life.
Technology?

Before I even thought to plug it in, the first thing I thought was, "Here at last is a great harvest of good quality opamps to use in my metal detectors..."
And indeed inside I came across a large number of opamps!
Alas!
Not one to catch my attention!
Not one that I would put in a detector!
They are all old and outdated.
That's why I decided not to tear it apart but to try it to see if it works, if it's correct.
My delight is endless when I see how well it works!
Where does all that quality come from?Comment

Hello ivconic and friends,
The other day a friend showed me a cell phone app that is really, really good !, it’s been around for a few years but not many people know about it, maybe you know it but for me it’s really good and it’s free, occasionally there’s some advertising but very little or when the app crashes it closes and opens again and voila.... I’ve been using it for months, apart from that I check my knowledge of geography. You can make a list of favourite stations etc ....and the cool thing is that you can see the time of the place. This app is called RADIO GARDEN, it’s free and takes up almost no memory… those who don’t know it will be delighted… especially if they are a radio fan.Comment

As for digital radio, including software radio, there are a million applications on those topics.
I have a Pinell SuperSound internet radio, made in Norway, with which I can listen to literally every radio station on the planet.
I choose a continent, a country, a city and it gets a list of stations.
On my Windows 10/11 desktop I have a "Mini Radio Player" app that works perfectly.
I have iOS and Android radio apps on my phones.
It's all right. Okay.
But to be able to analyze the differences in sound quality; it is necessary to listen to it on a quality amplifier with a quality sound system and at a slightly higher power.
Someone will also suggest instruments like spectrum analyzers, oscilloscopes, various EQ software, ok.
But what the ear hears and what sounds good is often an individual thing.
Despite the super powerful ADC-DAC systems, if you listen to the guy in the video from post #1; you will understand what the point of this topic is.
...
I have this radio, among many others I have, I favor it because it works unexpectedly well:

I should probably put this in a separate thread... but it's okay to be here.
Here's an idea for a bunch of interesting experiments.
First download and set up this software (sometimes it downloads dotnet.. the installation that is needed).
https://airspy.com/download/
Then connect a few meters of quality coaxial cable to the MIC input of your desktop/laptop computer (shorter or longr cable if necessary) and tie a coil with as many windings as possible to the end of the cable.
It is desirable that the coil is wound over a ferrite rod from an antenna.
And this is where my genius comes in again... and my bad side is that I can't keep secrets, sometimes I act like a torn sack with lots of holes trying to transfer water!
However, "my Highness" has no problem with that... you should always give a little bit to the poor people!
Instead of bothering with idiotic manual winding of coils... READ what's coming next, bellow:
Do you know what an electrovalve for water for washing machines is? Every washing machine has two of them at least.
They are very cheap. You need to bend and remove the metal parts and holders with strong pliers and you will be left with a very nice and properly wound coil with 2 leads.
The icing on the cake is the hole through that coil, which has the ideal width for threading a ferrite rod from some discarded antenna.
And that's how you got the perfect ULF antenna in no time!
Stop the standing ovations... my ego is huge, I don't need any extra boosts!
So you connect such an "antenna" to the other end of the coaxial cable...
In the SDR# software, select the appropriate input:
And "voila"... you have free ULF reception with a spectrum analyzer.
With which you can listen to signals below 22kHz.
"Raw" or "CW"... I leave the rest to your imagination...

This forum would definately fail without my help... with my help it obviously fails much faster!

You can really do a lot with this "setup", the only limit is your imagination.
I will give you two practical examples of use.
If you want to "visualize" the range of interference caused by the city grid (50/60Hz) and the bunch of harmonics that accompany it...
especially if you want to see the disastrous behavior of cheap LED lighting in your house, as well as the even more disastrous effect of operation of various switch power supplies...
this is the right instrument for you! The same goes for EFI.
But you might also want to "see" what's going on around the coils of your metal detector!?! Aha!
Instead of the described antenna, you might think of connecting your PI or VLF I/B coil to the MIC input!? Interesting!??
Enough with the standing ovations, I'm falling off the stage!

Thank you very much Ivconic for the tip and the software "airspy.com" i will experiment soon!Comment

I have been following the development of that open source software for several years.
The people working on it deserve the best praise.
With a little imagination, a lot can be achieved with this software.
