Editor's Note: This is the first article in CA's new "Digital Vinyl" series. The upcoming topics include dynamic range, loudness wars, high resolution digital, disadvantages of vinyl and myths, clocks and sample rates, mechanical reflections in vinyl and reconstruction of the digital signal in real time, among others. This series will focus on both digital and analog audio, in addition each article will include terrific audio samples from Igor's project. What follows is an introduction of the series' author. I think you'll find both Igor and the series refreshing. - CC
First of all I want to thank Chris, that he decided to open a new regular column on the subject, which can cause a lot of controversy and debate. Vinyl, LP - these are concepts that cause many of us, fans of digital audio, to usually smile, and often contemptuously. According to my observations, many members of CA have prejudices against these categories, and these prejudices have the right to exist. I initially want to assure all of you that we are talking here not about vinyl, but only about digital sound, and even more about computer digital sound.
Now a little about myself. My name is Igor and I am from Ukraine. My official introduction to CA (I am referring to registration as a member of the forum, as I have many years of browsing it without registration) began very interesting. It began with a ban. Not just a ban, a lifetime ban. Again I want to thank Chris that he, despite all the seeming obviousness of this incident, hasn't shown prejudice, and patiently handled this conflict. This is one of the many good traits of Chris, which all of us on the forum have respect and love.
My acquaintance with music began when I was 5 years old and my parents enrolled me into music school to learn the violin. Then there was piano and percussion. Thus all my childhood and adolescence was integrally associated with music. After graduating from the conservatory I began my professional career in a pop-rock band. As I practiced music composition and arrangement, I spent much time in multiple studios and "just knew the kitchen." I am writing all of this just to make it clear that I am familiar with the music not only as a listener, but as a creator, as we say - "on both sides of the barricades."
This digital vinyl project is the result of my disappointment and dissatisfaction with digital sound. This disappointment stretches back to the late 80s, when I was careless enough to switch from analog to a digital setup – the so called “revolution of the future." While having very modest entry level audio system at the time (turntable with built-in phono-preamp for about $300, integral tube-amplifier and speakers – all together for about $1,500) I had incredible satisfaction listening to good LP Records, each time getting a huge release of endorphins in my brain.
Later, due to certain circumstances, I did not listen to music for a few years (professionally engaged in the band's rehearsals, concerts, studio recordings) and even sold my TT with the whole collection of my LPs.
I returned to listening to the music already as a victim of digital progress with a costly CD Player.
You know, we all have favorite albums that sound best on our systems, so we often listen to these albums. The first thing I did – I bought these albums in the best (Collector edition – special edition) quality available published on CDs. And then I tried listening to them for the first time – in the same room, with the same amplifier and speakers that I used to with my vinyl collection. We have some memory of sound, some expectations for what should happen. I was simply shocked, the impression was that someone sucked all the juice, all the life out of these records. I then went to all of my friends to try their setup with these records. The result was the same everywhere. I was very disappointed. Practicality and progress won, but the beauty and all the magic of the sound disappeared as well as emotion and pleasure of listening to it.
It was the first disappointment, and sadly, not the last. For the last almost 30 years, I have repeatedly made attempts at digitizing Vinyl, trying to at least draw near the magic of Vinyl in the digital domain. I used various TT system (including very expensive ones), a variety of professional equipment and software, but the result was always inadequate.
There was a clear boundary, a barrier that separated the two worlds – analog (LP) and digital, always in favor of the first one.
A few years ago a completely new concept of digitizing Vinyl appeared, proposed by Dr. Rob Robinson (Channel D) who implemented it in his revolutionary software – Pure Vinyl. This concept and the latest technology in professional digital audio equipment (now available to me) brought vinyl digitization to a radically different level. Almost two years of endless recording, testing, comparing and selection of components (devices and cables) gave a stunning result which exceeded all of my expectations.
Dr. Rob Robinson noted that Pure Vinyl is:
"Linking analog LP playback with the precision of high-resolution digital music reproduction"
and
"Single point of integration for analog and digitally sourced music."
I totally agree with him, and just want to note: In tandem with quality equipment Pure Vinyl is not just a bridge that connects the two worlds of audio – it’s a real highway!
I purposefully did not touch on many important technical aspects connected with the project in this introductory article, in order not to discourage forum members from listening to demo samples, but we're sure to discuss them in the following articles on this project.
As the first topic for discussion I see "Time domain of the sound signal or what is more important for listening to music - static or dynamic (in a sense of time) characteristics of the sound signal?". Because undistorted, "virgin" time domain is the main reason why extreme audiophiles love vinyl. This is also one of the reasons why we like MQA so much.
And now I, along with Chris invite all of you to listen to short demos, and share your experience and observations!
Thank you,
Igor
