Important Lessons We Learned from Record Experiments
Part one of this commentary concerns the random nature of record making processes. It can be found here.
A Heavy Vinyl Shootout
A number of years ago (2011?) the opportunity to crack open two brand new sealed copies of a recently remastered Heavy Vinyl pressing came our way.
At the time, we were told that with this pressing every effort was made to produce the highest quality product and to maintain the utmost in quality control throughout the production process. They were adamant that every copy produced, from first to last, would be indestiguishable from any other. Not just in terms of surfaces, but sound quality too.
To accomplish this feat, the producer used the real master tapes (we were told, no reason to doubt him), had a well known mastering engineer do the mastering at a highly-regarded studio, then had a well-known audiophile pressing plant in Germany make the record, using the finest vinyl compounds available, in presses that meet the highest standards in the industry, operated by skilled individual of the utmost professionalism.
Any stamper would be replaced long before it could possibly be showing any wear.
All the metal mothers and stampers would be made in a way designed to eliminate all variation.
One and only one complete run would be made. If another was needed at some later date the whole process would have to be started over from scratch using the same strict quality controls.
Every copy would be quiet, the sound would be of the highest audiophile quality, and, more to the point, every copy — from number 001 all the way to number 7,500 — would sound as good as any other.
Our Experience
As you might have guessed by now, our opinion as to the possibility of these results being achievable is that they are not. They are simply impossible.
Bear in mind that this is an opinion supported by the playing of thousands and thousands of records, including sometimes more than a hundred of the same title, and having them all sound different, to one degree or another.
So we proceeded to test the proposition that by exercising maximal control over all the known variables of record production, using the most exacting standards at each and every step, two copies of the same record, chosen at random, would sound the same.
We picked a song, cued it up and listened to it for a minute or so. Then we put the other copy on our table, cued up the same track and let it rip.
Falsified in Fifteen Seconds
Immediately the sound was different and, importantly, quite a bit better. The first big cymbal splash was brighter and more life-like, with more extended high frequencies. The bass was better too: deeper, as well as more solid and easier to follow. All of this was evident within the first fifteen seconds of playing the second copy. So much for controlling the variables.
The random variability inherent in the record making process cannot be overcome by best practices and high standards. The process is complex, not well understood, and surely stochastic; some parts of it can be controlled but not all the parts of it can be controlled, which means that the finished product will have some unavoidable element of randomness.
Critically auditioning literally thousands and thousands of records during our 35+ years in the record business has convinced us that the only way to find good records is to clean them, play them and critique them. Not one at a time, but by the dozens.
That single, simple approach, tedious and time-consuming though it may be, has the potential to teach you more about records and sound than any other.
We might even go so far as to say that no other approach to learning how to listen critically — none that we are aware of anyway — works remotely as well.
