Straight output of a Sigma Delta ADC which is a filter. Hans those pictures are of infinite BW signals they don't exist in any real world. If the recording process obeys Nyquist the DAC can not see those signals. If they could show a cymbal crash displaced over +-5 feet they would have, but they can't. The point is they can't make their point with real audio signals, or at least their point would be very weak.

The important question here is: What do all those high frequencies represent?
A simple test will tell you: Record the record with the highest possible sample rate. High pass the file at 20kHz. Then pitch shift the file down a couple of octaves. What do you hear?
I have no vinyl to record, so can't do the test. I can do the high pass filtering and pitch shifting, so if others are willing to record, I can process the files.
A significant portion is synthesized harmonics.
Sounds like a good experiment you propose.
Greg Reirson over at Gearslutz ran some experiments in which he used band-limited (22 kHz) source material, cut it to vinyl, transferred the vinyl at 96 kHz and analyzed the results. The last octave looked similar to the vinyl I showed previously. Harmonics appeared that weren't in the original source. I'll see if I can find that link....
With FFTs that look like this it's no big surprise we see harmonic enhancement. Note how H2 dominates H3.

My hunch,
I think there are a few aspects to digital. I've read a lot from different mastering engineers. I gather that the lp even with it's limitation has good dynamic range of 75db and good stereo separation. The 16 bit cd vs the 24 bit. I was reading, maybe Ludwig saying if you listened to 16 then 24 for only a few minutes you wouldn't hear a difference from the same mastering. But if you played the 24 bit recording all the way through- 45 minutes or an hr and then went to the 16 bit. You would definitely hear it.
What's the stereo separation at 5 khz or 10 khz on a cd playback? Overtones...
In the end good mastering makes a huge difference. Maybe having more limited storage space forces someone to do a better job with the lp?

While this paper does explain why, does someone prefer vinyl, it does show, that it is not related to the objective quality of sound

...i´m sure the point it´s not in format itself, but the person responsible at that time of recording.
as buyer of hdtracks, it is VERY NOTICEABLE old vs new albums, how the whole thing sounds.
IMHO hi-res digital is the maximum achievable quality, system itself affects music very little
lp has extra touch to it, you are handling a physical spinning thing, just watching it spin gives feelings. huge photos, booklets...etc.
due to recording limitations, stupid things like loudness wars are impossible on analog formats.
that can be the reason, why general public prefers lp.

But it has unlimited resolution.
And good records will captivate you a lot more than the cd version. Also the cd version often sounds flat, cold and lifeless in comparison.
For me there is no comparison.
For me CD just sounds like a higher quality mp3.
Oh dear! Practically everything about LP is inferior to CD. Of course, some people don't like high fidelity sound reproduction and describe it as "thinner,sterile and void".Dude111 said:
LP is limited by vinyl particle size (and dust particle size). CD, with correct dithering, has unlimited resolution.globalplayer said:
No.
Yes, some people who don't like hi-fi describe it as "flat, cold and lifeless".
Maybe you need a better CD player? Or maybe you need a better turntable/cartridge, as you may have become used to the problems of LP in your system and find anything different to be inferior.
I have done lots of measurements on LP, dynamic range is 50dB on a good day, tops. Most were around 45dB. That's the range between max output level and the surface noise, which limits the resolution.
CD resolution is about 100 times more (40dB). Even more (much more) if dithered.

That's down to the way it has been mixed/remastered. Some of the earlier CDs where they didn't get too carried away during the remastering are the best. It's also amazing what they've been able to do when it comes to cleaning up old recordings, this cd is a case in point

If you read some of the LP mastering forums, you'll come across threads where the mastering engineers will talk about monitoring the LP master as it's being cut from a digital file. Often they describe the LP cut as adding a certain "something" pleasant to the sound. The term I've seen most is "depth". No one really explains why that would be. Sometimes that LP master playback is recorded and used for the CD master. Yes, really.
