The nature of analog is that it does not have sample rate. However due to the physical limitations of the medium we can expect response upwards of about 20k cps or hz, and even higher. Below that there is no Gating, frames, sampling etc.. Like analog magnetic tape, we are limited by other factors like tape speed and groove size/lp speed. Analog suffers other problems that affect resolution like noise of all kinds and durability of the medium as well as component issues.(surface, system etc) There is no visual analog data storage equivalent that you can use that applies to analog sound.

Some analogies simply don't work. I always wondered though if the undulations in the groove cause the stylus to vibrate, are we still not dealing with some sort of discrete series of motions and, consequently, that there is bound to be some discontinuity between these, laying the argument of the superiority of analogue reproduciton as being based on some uninterrupted continous wave the way God intended music to be, a little bare?

==No more than it ever was 50 years ago when Lp was king.
I maintain that no medium is best, each has problems and always will. I may see holographic 3D optical storage mediums for cheap in my lifetime but will they let you hear "the hairdoo's"? I doubt faster sample rates will change the sound much. I think digital is quite good today. I find analogue far more problematic and disapointing when playback noise takes away from the music. Still, the sheer beauty of the performance can be all powerfull. I have a treasured Calvin Jackson and his All Stars lp from '57, scratched, furrowed and mono still delivers far more energy, tonal character, and ambiance than most any digital I've heard. All those scratches won't impress anyone but a music lover, and that's why I still play it. I listen for materials sounds ie: drumsticks, maple wood tips or nylon, Ludwig or Pearl. You can do that with LP in spite of spurious stylus movements. On the other hand the tonal character changes record to record. Stylus cleanlines is a vocation. Got a pet in the house? TC
You have it right! It is the 'emotion' and the 'presence' that makes the difference. Would you believe that '78's' are even better? Some people, even intelligent and well trained, cannot hear this difference. Just today on FM radio, a caller said that he, at first, could not believe that opera would be effectively transcribed to CD in any quantity that he could be happy with. NOW, he is taking his CD's and reducing them to MP3! Does this person hear music like you and I do? I doubt it.
