These Pink Label Pressings Can Sound Good, But Great? Not a Chance

Hot Stamper Pressings of Music on Island Records Available Now

Below you will see the bottom part of the stamper sheet for a shootout we did recently.

Please note that the album you see pictured is not the one we are discussing here.

It very well could have been been a Jethro Tull album, but all we can say for sure is that it was definitely an album on Island, which just happens to be one of our favorite labels, for sound and music.

The earliest pressings for many records on the Island label are not very good. This one — again, not for This Was, for some other record — is not a bad sounding pressing.

With grades of 1.5+ on both sides, it fits comfortably in our section for good, not great sounding LPs — but the right reissues from the 70s are a big step up in class sonically. They’re the ones that win shootouts, not these Pink Label LPs.

It’s big and clear but dry and spitty and badly needs tubes in the cutting chain.

Do the record collectors who prize the Pink Label pressings above all others notice these things?

Do the audiophiles who play them?

Been There, Done That

We’ve run into so many sonically-flawed Pink Label Islands by now that hearing one sound lackluster if not actually awful doesn’t phase us in the least. Some of the other Pink Labels that never win shootouts can be found here.

What Lessons Can We Take from this Columbia Shootout?

Hot Stamper Pressings of Vintage Columbia Albums Available Now

Recently we conducted a shootout for one of our favorite Columbia recordings, one that we had auditioned many times before and for which we knew the music and the general 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 plenty of stamper information on this blog, including some of the worst ones we’ve had the misfortune to run into, but rarely do we feel the need to give out the really good ones. After decades of doing this kind of work, the time and effort that has gone into finding them is beyond calculation.

When we do give out the best stampers, as is the case here (3BA baby!), we make a point of keeping the title under wraps.

We are not the least bit interested in putting ourselves out of business.

The discussion for today revolves around the idea held by a great many audiophiles that the original White Print 360 label pressings are going to be the best sounding for any title that was made starting with that label in the early-60s.

(The Black Print 360 mono is an example of the mono labels being a bit behind the times as far as I can tell.)

Note that we did not bother to put any of the 70s Red Label Columbia pressings in the shootout. We’ve been down that road with this title before, and we have yet to hear one worth the vinyl wasted on it.

Columbia, like most labels, seems to have made very little effort with the sound quality of their reissues. Perhaps it was the result of all the bad transistor equipment in the studios by the time the 70s rolled around, but that would be speculation on my part, as well as something that would be very hard to find evidence for one way or the other.

We did find one Monk record that sounded better on the Red Label reissue, and readers of this blog should easily be able to find out which one it is by reading our many reviews for Monk’s recorded output.

We have two new lists for those who would like to know which Columbia labels win shootouts — one for 6-Eye winners and one for 360 Label winners.

What interests me in these findings is the following:

  • Both of our shootout winning copies had the same stampers. Can that really be a coincidence?
  • The shootout winner for side one is 3BA.
  • Two copies with stampers very similar to that one, 3AB, did noticeably worse, 2+ and 1.5+.
  • And the worst of the White Print 360 Label pressings barely earned a Hot Stamper grade at all.
  • They are on the same original label as the other copies, but for some reason they don’t sound as good. Why is that?

If an audiophile collector were to go to Discogs, find a nice clean copy on the early label and buy it, he might find that he know owns a top quality sounding copy, a pretty good sounding copy, or a not-nearly-as-good sounding copy as he’d hoped for, depending on his luck.

And what would he know about the quality of the recording? About that thing that audiophiles and record collectors seem to reference so often, “the master tape,” as if they have any way of knowing about the sound of a tape they have never come into contact with.

Just Assume

If he had a killer 3BA, wouldn’t he just assume that for some reason the recording must be amazing and consider himself lucky to find such a wonderful record to play.

Why one set of stampers sounds so much better than another set, or the same or a similar set on a different pressing, is a mystery, and it’s one that we confidently predict will never be solved.

Does anyone have a practical way to get around the reality that allows one set of stampers to sound great and the same or a similar set of stampers to sound no better than very good, if that?

Well, we can’t say there is a practical way, but we do know of an impractical one. We’ve been practicing and refining that one for more than twenty years.

We just play lots and lots of copies of the albums to find out how they sound.

On this Mystery London, The Reissues Have Lately Been Letting Us Down

Hot Stamper Pressings of Recordings by Decca Available Now

The record you see pictured is not the record we will be discussing in this post.

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

We’ve lately been giving out much more stamper information than we used to, in some cases including the actual stamper sheets compiled from the shootout — winners, losers, and everything in between — but for now we are keeping this title close to the vest.

This pressing was not as bad as many of the golden age classical titles we play. (See links below.)

Although it has the potential to sound amazingly good on the early labels, the second label London pressings never seem to do much better than 1.5+, a barely passing Hot Stamper grade.

It’s small, stuck in the speakers, and had no real top end. We judge the best pressings on the second label with these stampers to have good, not great sound quality.

1.5+ is four grades down from the top copy.

That’s a steep dropoff as far as we’re concerned. 1.5+ only hints at how good a recording this London can be on the best early pressings.

To see more records that earned the 1.5+ grade, please click here. (Incidentally, some of them are even on Heavy Vinyl. The better modern pressings have sometimes, if rarely, been known to earn Hot Stamper grades, and one shocked the hell out of us by actually winning a shootout. Wouldn’t you like to know which one!)

For those who might be interested, there’s more on our grading scale here.


Here are reviews for some of the titles we’ve auditioned, broken down into the three major labels that account for most of the best classical and orchestral titles we’ve had the pleasure to play.

  • London/Decca records with weak sound or performances
  • Mercury records with weak sound or performances
  • RCA records with weak sound or performances

We’ve auditioned countless pressings in the 37 years we’ve been in business — buying, cleaning and playing them by the thousands.

THE Hot Ticket, or Just One of a Bunch of Potentially Hot Tickets?

Hot Stamper Pressings of Rock and Pop Albums Available Now

Below you will find the stamper sheet for a title from a recent shootout we did for a rock record whose name we are not revealing.

You may have noticed that when we give out the stampers for the top copies, we rarely identify the title of the record with those Shootout Winning stampers.

As you can well imagine, our sizable investments in research and development over the course of decades make up a big part of the costs we must pass on to our customers.

I can’t say this title is typical of most of the rock and pop we play, but it’s not all that unusual either.

Obviously, knowing the “right” stamper information in this case gets you in the ballpark, but it won’t help you hit the grand slam home run you want to. To do that you have to clean and play about five copies the way we did.

Hot Stamper shootouts may be expensive, they may be a lot of work, but our experience tells us there is simply no other way to find top quality pressings — the ones that earn the 3+ grades, not the 1.5+ grades.

They might all look the same, but they sure don’t sound the same.

In this particular case, the import pressings we played — the ones we expected to do the best as a matter of fact — had by far the worse sound.  There were a couple of them, there was a domestic reissue, and there were five originals: eight records in total.

Changes for 2024

Beginning in 2024 we decided to make available to our readers a great deal of the pressing information we’ve compiled over the last twenty years, under these headings:

How Can the Best Stampers Also Be Some of the Worst?

Hot Stamper Pressings of Vintage Columbia Albums Available Now

Recently we conducted a shootout for a favorite Columbia recording, one that we had auditioned a couple of times before and one for which we knew the music and the general 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. (When we do give out the best stampers, we keep the title under wraps. We are not the least bit interested in putting ourselves out of business.)

The discussion for today revolves around the idea held by a great many audiophiles that the 6-Eye pressings are going to be the best sounding of almost any album they might happen to run across.

And, to be fair, in the case of this mysterious album, they’re right.

What interests me in these findings is that the stampers for a shootout winning copy, the top one, are almost identical to the one that came in close to last in the shootout outside of the Columbia Special Products reissue, with decent, respectable but far from shootout winning grades of 1.5+ and 2+.

One of the 1K side ones was the best we played, and one was very bright.

If an audiophile collector were to go to Discogs, find the IK pressings, he could either find himself with a top quality copy, or a not-nearly-as-good copy, depending on his luck.

Why one set of stampers sounds so much better than another set, or the same or similar set on a different pressing, is a mystery, and it’s one that we confidently predict will never be solved.

Does anyone have a practical way to get around the unfortunate reality that allows one set of stampers to sound great and the same or a similar set of stampers to sound no better than very good, if that?

This Mercury May Have the Same Stampers on Both Sides, But the Sound Is Very, Very Different

Hot Stamper Pressings of Mercury Classical Recordings Available Now

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

In many 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. (Both beat the pants off the awful Classic Records pressing.

But sometimes the RFR pressings — which, as I am sure you know, can be the earliest stampers for some titles — are nothing special on one side or the other. That is exactly the case here.

Keep in mind that the stamper numbers you see above 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 the identify of this title close to the vest.

We are not able to predict what stampers will win a shootout before we actually sit down to play all our copies.

It turns out that the FR pressings did not sound as good as some of other pressings. The RFR stampers came in somewhere in the middle of the pack, an average of 2+, but a hard record to sell with such very different sounding sides.

This is why we do shootouts, and why you must do them too, if owning the highest quality pressings is important to you.

Fortunately for readers of this blog, our methods are explained in detail, free of charge.

We’ve also written quite a few commentaries to help audiophiles improve the way they think about records.

I implore everyone who wants to make progress in this hobby to learn from the mistakes we’ve made. There are 146 “we were wrong” listings on the site as of this writing, and we learned something from every damn one of them, painful and costly as those experiences may have been.

Are White Label Promos the Way to Go on this Mystery Columbia Jazz Album?

Hot Stamper Pressings of Vintage Columbia Albums Available Now

Recently we conducted a shootout for a Columbia recording, one that we had auditioned a couple of times before and one for which we knew the music and the general 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. (When we do give out the best stampers, we keep the title a mystery. We are not the least bit interested in putting ourselves out of business.)

The discussion for today revolves around the idea held by a great many audiophiles that the White Label Promo copies are going to be the best sounding pressings of almost any album they might happen to run across.

And, to be fair, in the case of this mysterious double album, they’re right.

Our two best sounding copies were White Label Promos.

What interests me in these findings is that the stampers for a White Label Promo copy, the second one, the one with mostly Super Hot grades, are almost identical to the one that came in last in the shootout, with barely passable grades.

If an audiophile collector were to go to Discogs, find the WLP pressings, write down their stampers, and then check them against the copies he owned or might want to buy, he could either find himself with a top quality copy, or a not-nearly-as-good copy, depending on his luck. (And side four of the worst pressing earned a sub-Hot Stamper grade of 1+.)

Why one set of stampers sounds so much better than another set, or the same or similar set on a different pressing, is a mystery.

Does anyone have a practical way to get around the unfortunate reality that allows one set of stampers to sound great and the same or a similar set of stampers to sound not much better than decent?

Well, we can’t say there is a practical way, but we do know of an impractical one. We’ve been practicing and refining that one for more than twenty years.

The Wrong Stampers on Some Albums Are Shockingly Bad

Hot Stamper Pressings of the Music of Carly Simon Available Now

Below you will see the bottom part of the stamper sheet for a shootout we did recently.

Please note that the album you see pictured is not the record we are discussing here. It very well could have been been a Carly Simon album, or something from some other artist, but all we can say for sure is that it was definitely an album from the 70s on Elektra.

We are not revealing what record had these stampers and earned these grades for the simple reason that avoiding these bad labels for the record in question would make it fairly easy to figure out what the better pressings of the album might be.

As I’m sure you can understand, we want you to buy the copy with the Hottest Stampers from us, not find one on your own.

We’re happy to be moderately helpful, but naturally we find it necessary to draw the line somewhere, and giving out the kind of information that makes it is easy to find the best pressings is where we have chosen to draw it. The top copies are the ones that pay the bills around here, and with a staff of ten, in California no less, the bills are sizable.

We appreciate your understanding.

Do All the Early Stamper Shaded Dog Pressings of this Title Sound Good?

Hot Stamper Pressings of Living Stereo Recordings Available Now

Below you will see the full stamper sheet for a shootout we did recently.

Note that the album you see pictured — LSC 2265 — is not the record we did this particular shootout for.

We are not revealing what mystery title had these stampers and earned these grades for the simple reason that we rarely if ever give out the specific information that identifies the best sounding pressing of any album.

As I’m sure you can understand, we want you to buy the copy with the Hottest Stampers from us, not find one on your own! We’re happy to be somewhat helpful, but naturally we find it necessary to draw the line somewhere, and giving out “the shootout winning stampers” are where we choose to draw it.

One set of stampers for the mystery Shaded Dog pressings we played in our most recent shootout sounded consistently subpar.

The Reissues Consistently Beat the Originals on this Mercury

Hot Stamper Pressings of Mercury Classical Records Available Now

For Mercury classical and orchestral recordings, the original FR 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.

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

The notes for the FR original pressings we played read:

  • Less spacious, more bright and flat.

They’re not bad sounding, they’re just not as good sounding as the RFR reissues, which, incidentally, won the shootout.

We’ve lately been giving out much more stamper information than we used to, but we make it a point to never give out the stamper information for our shootout winners, as finding those very special pressings has been the work of a lifetime and is certainly not something that should be given away for free.

Rules of Thumb

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?

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

Certainly not us, not until we had done the shootout.

The difference between the way we do things and the way others do them boils down to this: We assumed that the original could be the best, and then we tested that assumption and found out we were wrong.

But the right reissues of this Mercury — again not the ones you see pictured — is indeed an exceptionally good sounding record.

This is why we do shootouts, and why you must do them too, assuming that owning the highest quality pressings is important to you.
