Mastering on Mystery Titles

How Can the Best Stampers Also Be the Worst Stampers?

Hot Stamper Pressings of Contemporary Jazz Available Now

Recently we conducted a shootout for a superb Contemporary recording, one that we had auditioned a couple of times before and one which we felt we knew the music and the quality of the sound well.

It’s not the record you see pictured.

For now we’re keeping the title a mystery, consistent with the idea that we give out lots of bad stampers on this blog, but almost never do we give out the good ones.

Why, you ask?

The cost of discovering the right stampers is usually high, can take decades, and is fundamentally at the heart of how we make our money: by finding amazing sounding pressings with stampers we know to be good, cleaning them up, playing them, and offering those that, for whatever mysterious reasons that no one has figured out, including us, tend to have the best sounding grooves.

This time around we kept track of the stamper numbers for all the pressings we played, something we are making a habit of doing these days and using to highlight discoveries in the sound of the records we play.

In this case, we discovered an anomaly we thought we would bring to the audiophile world’s attention: the fact that the stampers for the best souding pressing were also the stampers for the worst sounding pressing, because they were the stampers for all the pressings.

One copy earned our White Hot Stamper grade, our highest, for its clearly superior sound, and another one earned our lowest Hot Stamper grade of 1.5+. The rest were quite good, in between those two, which is a very common outcome for most of our shootouts: lots of records in the middle of the distribution, some winners at the top and some losers at the bottom.

After You’ve Played 100 Copies of the Album, What’s Left to Learn?

UPDATE 2026

This commentary is at least ten years old. We can’t say that a red label reissue like the one discussed below would do as well under the improved shootout conditions in our new studio, but the possibility exists, which is the point of the story we are telling here.

A common misconception of many of those visiting the site for the first time is that we think we know it all.

Nothing could be further from the truth. We definitely do not know it all. We learn something new about records with practically every shootout.

Not This Title

Case in point: the record you do NOT see pictured above. (The record we recently learned something new about — this, after having played scores and scores of copies over the years — will remain a secret for the time being. At least until we find another one.)

In 2013 we played a red label Columbia reissue of a famous 60s rock record (again, not shown) that had the best side two we had ever heard. Up to that point no copy other than the 360 original had ever won a shootout, and we’ve done plenty. Lo and behold, here was a reissue that put them all to shame.

I’m still in shock from the experience to tell you the truth, but what a blast it was to hear it!

The recording, which I first played more than 40 years ago at the tender age of 16, was now bigger, less murky and more energetic than ever before. Had you asked me, I would have confidently told you not to waste your time with the second pressing, to stick to the 360s on that title, and I would have been wrong wrong wrong.

How Wrong?

But wait a minute. The 360 original will probably beat 49 out of 50 red label reissue copies on side two, and the best 360 original could not be beaten on side one by any other pressing. When you stop to think about it, we weren’t very wrong at all.

Let’s just say our understanding was incomplete.

This is why we prefer to offer actual physical records rather than just advice, although it’s clear for all to see that we happily do both, and, moreover, we certainly feel qualified — as qualified as anyone can be — to offer up our opinions, since our opinions are based on a great deal of experimental data.

Having big piles of cleaned records at one’s disposal is fundamentally important to this kind of operation. In our experience, shootouts using only a small number of pressings have relatively little value. They are best seen as a guide for the next, more comprehensive attempt to find out what might be the truly killer pressings of any given album.

Maybe We SHOULD Start Buying Blue Notes on the Early Labels

Hot Stamper Pressings of Blue Note Albums Available Now

If there are record companies whose fans are extremely particular about the labels of the pressings they prefer, Blue Note has to be right at the top of that list.

The consensus among record collectors seems to be that the early label Blue Notes are practically guaranteed to have the best sound. In top condition they often sell for many thousands of dollars, far more than we have ever charged for any Hot Stamper Blue Note pressing

We are on record as not favoring early labels over later ones, absent the evidence to support such bias, but perhaps there actually are some records you should be buying based on their labels. This one, for example.

If all the stampers of a title are the same and they’re all cut by Rudy Van Gelder — early labels, middle labels and later labels alike — what do you use to guide you when trying to find the best sounding pressings?

This is precisely the conundrum that an audiophile would be faced with as he goes about trying to find the best sounding pressings of the Blue Note album whose stamper sheet you see below.

This stamper sheet reflects a fairly typical shootout for a Blue Note pressing. It’s hard to find six clean copies no matter what the title is. We probably returned or gave up on half the copies we bought, so we might have had to buy nine in order to shootout six.

(Note that there is nothing on any label after the White B from the 70s. We have never heard any title with an 80s label or later sound worth a damn so we stopped buying them a long time ago.)

Drawing Conclusions

Let’s look at some of the conclusions the typical record collector/audiophile might draw from the information above.

For example:

1.) I have a Blue Note with Van Gelder stamps and it’s decent sounding but I like [fill in the blank with some other pressing] better. Since all the pressings are cut by him, he must not have done a very good job. Thank goodness modern mastering engineer X came along to finally bring out the sound of the master tape that he was not able to do.

That’s an easy one to rebut. The later pressings cut by Rudy are consistently worse sounding than the earlier ones in the case of this title. If you don’t have a big batch to work through, however, you simply have now way of knowing that fact, and therefore whatever conclusions you choose to draw from a too-small pool of pressings are suspect at best.

The Original Mercury Pressings Don’t Sound Good on this Title, But Why?

Hot Stamper Pressings of Mercury Classical Recordings Available Now

For Mercury classical and orchestral recordings, the original FR pressings (when there are such pressings) on the plum label are the way to go, right? 

In some cases, yes. We talk about how much better the FR pressings for The Firebird are compared to the much more common, and still quite good, M2 reissue pressings here.

And the FR pressing of the Rachmaninoff record you see pictured above may indeed have the best sound.

The stamper numbers you see below belong to a different album.

(We’ve lately been giving out much more stamper information than we used to, but for now we are keeping this title closer to the vest.)

Note that we had FR1, FR2 and FR3, all originals, yet none of them could be considered good enough to offer our customers.

It’s just another one of a number of rules of thumb collectors use (“A method or procedure derived entirely from practice or experience, without any basis in scientific knowledge; a roughly practical method.”), one that will sometimes lead you astray if what you are trying to find are not just good sounding pressings of albums, but the best sounding pressings of albums.

Same with reissue versus original. Nice rule of thumb, but it only works, to the extent that it works at all, if you have enough copies of the title to know that you’re not just assuming the original is better. You actually have the data — gathered from the other LPs you have played — to back it up.

Who knew the recording would sound so much better on the right reissue pressings?

Our Search for Shootout Winning Sound on Modern Vinyl Finally Pays Off

Our (Incomplete) List of Potentially Very Good Sounding OJC Pressings

It has finally come to pass. A modern pressing has won a shootout.

Having auditioned more than a dozen modern (post-2000) OJC pressings and having had them fall far short of the mark again and again — when they weren’t just plain awful — we have now discovered one that can win a shootout.

As you imagine, this came as quite a shock.

We weren’t sure precisely which of the many OJC pressings our shootout winner was until we looked up the stamper numbers on Discogs. To our surprise, it had clearly been made sometime in the the 21st century.

That Never Happens

This has never happened before. No record made since 2000 has ever won a shootout against a vintage pressing of the same title.

Modern records range from awful to very good, but one quality they have never had is the ability to be the best of the best.

Now one has.
