The audiophiles that supports LPs ( as me. ) almost always speak of digital aliasing that today really does not exist through the aliasing filrters and always speak of the famous jitter an discontinuity of the digital signal/sampling but things are that LP playback has its own discontuity in the signal that the cartridge/tonearm pick-up:
The lost of information during LP playback exist at the cartridge stylus tip when ridding the groove modulations because that tiny stylus tip can't pick-up all the information recorded in those LP grooves and not only that but at that micro level the stylus tip jumps between grooves modulations, very tiny and microscopic level jumps: this is that the stylus tip momentaneous lost direct contact with the vinyl surface.
This link about digital is interesting for we audiophiles:
I like both formats and I know for sure that digital is a superior one. LP experience pass though a nigthmare of multiple steps before the sound comes from the speakers. These comes from a very interesting thread where at least two members of WBF participated:
The MUSIC sound is developed by an extremely movement sensitive sensor named cartridge that pick up tiny/micro movements/resonances/vibrations/feedback and the like coming by inside the TT/tonearm/tonearm board/LP/cartridge body ( at least. ).
So it does not matters if air bearing or DD or idlerdrive all of them are " resonating " somewhere in different way ( using the same cartridge/tonearm. ) and the cartridge is taking that overall non damped resonances/vibrations/feedback or whatever you want and for me it's here from where comes all differences in between, at least the detectable ones.
and analize a little what can modulates the sound you are listening other that the recorded groove modulations because I think that those other very tiny modulations puts its own " color " that can or not makes subttle differences :
all the 3 TTs are building with different blend of materials at each different places inside the whole TT and the blend of those materials and depending were are used tends to resonate/vibrate under dynamic stage/when are spinning during play. Those kind of very tiny or micro resonances/vibrations are different ( example: at different frequency. ) in each one of 3 TTs.
Now, what happens when the cartridge start to track/ride the LP groove modulations inside that whole mechanical circuit ( of course that it’s too the electrical side but it’s not the issue here. ) formed by: TT/tonearm/cartridge/LP?
As I said that circuit is a mechanical one and we can’t avoid the Newton Laws down there that lives down there one way or the other.
When the stylus start to ride the groove modulations that act develops many other tiny modulations as: feedback from the LP surface due to the friction of the stylus tip forces, the surface of the LP and due to that very high friction forces makes that exist too a feedback from the LP surface that is in touch with the platter or platter mat .
These are the first tiny developed modulations that goes mixed through the stylus/cantilever along the groove modulations ( the cartridge can’t make any difference between the groove modulations and the fedback modulations, just took it as it was the same. Is a very sensitive movements sensor. ).
That kind of feedback is followed by the cartridge body self feedback developed by the cantilever/stylus tracking and comes a new feedback movement that’s very fast transmitted to the cantilever and that same cartridge body feedback and through the top plate of the cartridge is transmitted to the tonearm headshel and starts to resonates in between ( this is totally independent of the resonance frequency in between the tonearm/cartridge and its compliance. ) and transmitted through the tonearm and then to the arm board but does not disappears because part of those kind of resonances/vibrations return through that arm board to the cantilever/stylus and mixed again with the true groove modulations.
Things do not finish here but I think you have the idea of what I try to explain about.
At the very high level of resolution that you are listening all those it matters ( at least for me ) because even that all 3 TTs are extremely well designed and excecuted and with the necessary overall damping ( that’s why the designers choosed materiasl and where to use it in the design. ) that each TT color exist and you are hearing it because no one can’t avoid it can’t makes that disappears from that mechanical circuit.
Normally those developed " modulations " affects the more to the bass range that at the same time it modulates ( color ) the other two frequency ranges.
Those nigthmare analog steps as the signal been recorded in a R2R tape where information is losted. Tape is neither infinite bandwidth nor infinite signal to noise, and even speed and level is not consistent, hence something is always "lost" but in digital alternative that just does not happens because what goes in the tape are only Zeros and Ones.
More steps as both RIAA eq. on analog during recording and playback with something additional to that: both RIAA eqs. never coincide in between: different frequency deviations.
The digital bass range specially the low bass can't be matched by the analog alternative and bass range modulates, through the developed harmonics, the other two frequency ranges. I think is more than enough. Sorry to take your precious time.
A true audiophile, at least, try to understand the whole digital medium and how it works and at the same time try to undersant the analog/LP/R2R medium and how it works and only then we audiophiles can understand the why's of its differences, advantages and disadvantages but at the end what it matters is the MUSIC and we true audiophiles must be aimed to listen digital medium along the analog one: not this or the other.
Exist a superiority of one of those mediums over the other? certainly yes but who cares about when we can enjoy MUSIC in both mediums: we have two alternatives about ! !
Regards and enjoy the MUSIC NOT DISTORTIONS.
