Facts are facts. Hard to dispute what is stated in the article.
Actually its easy to dispute because it contains a lot of misinformation that has become rote in the digital world.
Examples:
For starters, sound engineers have to pan bass frequencies to the center (reducing them), otherwise the needle could experience tracking errors. Treble has to be managed, and high frequencies must be de-essed to prevent sibilance from causing distortion. Low-frequency music can't have too many high amplitude (loud) sections, or the needle with bounce and skip out of the groove.
This statement from the article is false. The author should have said these things are done to reduce the cost of mastering. I found that if you spent enough time with the project you didn't have to do any of this, even in the face of out of phase bass.
To make vinyl mixes sound their best, they require a special RIAA equalizing curve. This curve can be reversed with a turntable preamp, but the process does result in data being lost, and mastering already makes the recording less faithful from the get-go.
Emphasis added- this bit is false. The RIAA pre-emphasis and de-emphasis does not result in lost 'data'.
CDs, by way of comparison, don't have to make virtually any compromises,
FWIW, LPs have bandwidth past 40KHz, CDs do not. They can also have timing issues (mostly a playback problem) depending on the quality of the timing circuits (clock) used. So this statement is not exactly false, its one of those 'depends' things...
Vinyl has a narrower dynamic range compared to CDs
This one is really misleading!! This is because LPs generally are not meant to be played in cars while the digital release usually is. So if the producer of the project is conscientious, he would have sent the digtial master to the LP mastering house with no DSP other than normalization, while the digital master will have compression. This is why a good LP release can have greater dynamic range than the digital release; its not a media thing so much as an industry thing.
CDs can reach up to 96 dB of range, while vinyl records are stuck at about 70 dB.
This statement is false. The signal to noise ratio of an LP is based mostly on how quiet the pressing plant is. QRP in Salinas, KS, decided to damp their pressing equipment so it would not shake and vibrate (due to steam pressure) while the pressing was cooling. By our measurements this resulted in a solid 10dB improvement in signal to noise; and that's being conservative. Projects we did through them were so quiet the noise floor was the playback electronics, not the surface noise.
If you're going to attack the LP as a medium, at least the attacks should be based on fact rather than some made-up stuff easily debunked.

Then there is "pre-echo," where sounds from a separate section of the vinyl get picked up before they play, particularly during a quiet section of a song.
In a nutshell, this is actually a tape thing, not an LP thing. Really thinking whomever wrote this stuff didn't know what they were talking about...
We mentioned earlier that bass frequencies are reduced on vinyl, but the problem goes deeper than that (pun, again, intended). The issue with bass is not just that it can lead to needle skips, but that too much of it can "steal" from other frequencies; it takes up a of ton physical space in the groove, and it has to rob that limited real estate from, you guessed it, the higher frequencies.
Aside from tracking errors, the way bass can make the needle bounce out of the groove may cause other parts of the songs to literally vanish. Most of this never happens since, as we mentioned, the bass is centered. But that just means aspects of the music could get lost in mastering before it reaches your ears, even when reversing the RIAA curve.
Because of this, people who originally listened to a song on a vinyl record will sometimes hear a new level and depth of bass on CD. However, there are adjustments to make bass more present in vinyl. You can reposition your speakers, get a preamp, change cartridges and platters, or increase the needle tracking weight. Otherwise, just use CDs; the bass is 100% there already.
Complete nonsense. I have to imagine the playback system they used was awful?? Bass isn't reduced on LPs, they are not mastered with 'reduced bass'. You don't get tracking errors if your arm and cartridge are set up properly; None. At. All.
High frequencies are another tricky subject when committing a mix to vinyl. We all learned in science class that lower frequencies, like bass, have long, stretched-out wavelengths. High frequencies like treble feature tighter, bunched-up peaks needed to produce the timbre of something like a high hat. As you can imagine, these grooves become incredibly tiny and fine on a vinyl record, making it very difficult for a needle to navigate through them at speed — or, in some cases, physically too small for a needle to fit into them at all.
The needle will then miss those pieces of the music entirely, and, in some cases, create distortion ewhen gliding over the peaks. Not only would you be missing those minuscule details in a song, distortion could be ruining the rest of the mix. These peaks are so problematic, in fact, that they can cause the machine cutting the lacquer to overheat, warping the vinyl and potentially creating distortion for all records made from the master stamper.
Again, pure nonsense! LPs have bandwidth past 40KHz as I mentioned earlier. We could cut 30KHz tones in the inner grooves with our Westerex 3D cutter and they would play back fine on an old Technics SL1200 with Grado Gold cartridge (we used this machine to know if we were cutting playable grooves). So none of what I quoted here was real. Just made up nonsense.
Do you want me to go on?? This article is a
bad place to look if you want to know about LP recording and playback.
