with all respect, atmasphere's posts here are invariably anecdotal in nature. The pattern is quite clear and repeated: the posts start with a blanket factual claim, and the evidence usually turns out to be what he did or saw in this or that situation. More than once his posts have even stated explicitly that what he did was in his opinion a best practice that was not consistently followed by others in the industry.
So to my eyes, most of atmasphere's posts are evidence for what he has done, and what he thinks or wishes would be (or would have been) industry standard practice, but were not.
My overall impression is that he wants to remind us that the LP-format manufacturing system has theoretical capabilities that are not as bad as sometimes stated, when all the stars align. That is, if absolutely best practice is employed at every single step:-
- The vinyl master tape has minimal adjustments from the studio master (rarely the case: it makes too much work for step 2), and
- The real-time operator gain control of the cutting lathe is done by an absolute master technician, highly focused on the job of riding the fine line of minimal compression, dynamic peaks that won't overload the best carts (totally ignoring the pretty bad carts with poor tracking limits that the vast majority of non-audiophile record player buyers will own), and getting a commercially viable number of minutes of music on a side, and willing to get it wrong and have to start over because there is no margin for error in this quest for perfection. (This would almost never happen in any commercial operation with dollars in mind), and
- The best possible vinyl quality and record formulation (eg thickness, weight) is used, and
- The first few vinyl samples off the press are microscopically examined and one sample chosen with the least pressing artefacts (ignoring the fact that most vinyl with be coming off a press that has has already printed thousands of records and is showing obvious wear degradation), then ...
- Yes then, the quality that is available in those grooves themselves can measure really quite well. Atmasphere's main claims end at this (idealised) point. Of course, that (theoretical) quality will start to disappear as soon as we play it on a record player, even a good one, which will still have a non-flat frequency response, channel separation that is poor at some frequencies and modest at best, a rarely-perfectly-aligned cartridge (master technician knowledge and skills required), non-linear tonearm distortion hovering around audible levels, skating distortion that even pulls the stylus out of equilibrium position, and don't get me started on dust and static.
And yet even that is with this perfect, idealised set of grooves. The real grooves in general practice don't meet conditions 1,2,3 or 4 above, not even close.
Talking about this idealised, shall I say potential, scenario, is like singing the praises of vinyl heaven while living in the reality of vinyl hell. Doing so makes one look irrelevant.
And that's with a
good record player as described in 5 above.
One horrendous thing about vinyl in practice is how far away from the idealised experience is the typical experience.
Let's consider the
median person (in terms of sound quality) who listens to vinyl at home. So, 50% of people playing records
globally have better sound quality than this person, and 50% have worse quality. What would the player typically be? I would suggest a $150 Crosley unit or equivalent, 5 years old, with the original cartridge that has never been adjusted, misaligned on a tonearm that has no skating adjustment, on a not-very-flat surface, with a stylus that has possibly never been cleaned and may be quite worn. And the records get an occasional wipe with a rag, if anything, and might even spend some time in the open on a nearby shelf.
The gap, between the typical record owner's experience described above, and the (pure, perfect, definitely not forever) potential of vinyl, is so horrendous that it is completely unacceptable in today's world, if overall sound quality is a priority.
Contrast that gap with the gap in sound quality experienced by the
median digital music consumer, compared to what was on the master tape used for the release. In general terms, the gap is tiny, perhaps completely inaudible. Both the source material and the player are effectively audibly transparent. And the sample consistency is close to 100%.
Compare that to vinyl. It's a revolution and a revelation.
The tragedy, on top of the above mentioned tragedies, is that our median record listener, described above, is being told that records deliver the best sound quality, and has no idea about any '
gap', and thinks it applies to his/her experience at home, and passes on the message.
Oh, did I mention that the median person's record catalog is half sourced from record fairs and second hand stores? Shall I describe 'the gap' between those records and the pure perfect ideal pristine format potential? It's not even a joke any more, right? And yet, our equivalent person who listens to digital, buys second hand and gets, almost every time, identical-to-ideal sound quality.
If you are "all about the music", then digital is literally the only sensible choice. To choose vinyl is to be "all about the gear". And that's fun, if all the above drama excites you, and circumventing it obsesses you. But it is what it is.
