This is a well-written article and at least goes to some length to try and objectively quantify stereotypical (pun not intended) analogue sound. However, having carefully read it twice, I notice there is no mention of engineers such as Kenneth Wilkinson who managed to preserve that "analogue warmth" regardless of whether he was working with pure tubed equipment in the early 60s, transistor-equipped, Dolby "A" equipment in the 70s or even Decca's early bespoke purely digital 18 bit, 48 KHz equipment in the very late 70s to very early 80s...
For my own part I am a vinyl listener but not because I think it is better. It is because many professional engineers simply do not have a sufficient grasp of digital technology to recognise the pitfalls and how easy it is to destroy the sound during the original recording session and during mastering or remastering. These are typically the same sort of people who go onto forums (not this one luckily, so far as I can tell)and say that because it is all noughts and ones, nothing matters. The problem is that with digital, everything matters and it matters - audibly - to an obsessive degree. Then these same type of people will provide links to their favourite blind test-of-the-month to back it all up. They are also the same people who when you try to look up their body of professional work, it either does not exist at all or it sounds like garbage. On the other hand, you then look up the body of work from those people who really do have a grasp on the pitfalls of digital (for example, blokes like Keith Johnson, Bernie Grundman, Bob Katz, Ryan Smith, etc, etc) and suddenly you find awards or praise left, right and centre and workloads so heavy that you have to wait a year to get a job done.
The bottom line is that I honestly cannot stand the term "analogue warmth" because I hear this so-called "warmth" daily in every single 24 bit digital file that I own, except the ones created by the type of "noughts and ones" people I mentioned in my second paragraph (yes, I can name precise names that come up over and over again but I am not going to for obvious reasons).
I will still only buy vinyl simply because I have invested too much money into it over the years and have quite a decent collection (for me) to then go around and spend far more on digital releases - even high res ones from people who really know what they are doing. It's got nothing to do with "analogue warmth". It is simply because there are both insufficient engineers living today who truly have the all-encompassing grasp on digital to make to truly transparent to the source and the fact that I made my format and investment decisions some years ago and wish to stick to it.
