Why Do the Later Stampers of this Shaded Dog Sound So Much Better than the Earlier Ones?

Hot Stamper Pressings of Living Stereo Recordings Available Now

For RCA classical and orchestral recordings, the earliest pressings on the Shaded Dog label, in stereo, tend to be the best sounding, right? 

Maybe. It’s an open question, at least it is for us when we consider how many exceptions to the rule we’ve run into over the 30+ years we’ve been buying and selling them.

If we tallied all the copies we’ve played and created a very large spreadsheet using the data, perhaps we could give you a better answer than “we don’t know,” but we’ve definitely never tallied them up and have no plans to do so. It sounds to me like a lot of work.

However, in our experience, and contrary to the conventional wisdom, sometimes the higher-numbered pressings are better sounding than the lower-numbered pressings. This is true of the stampers for the Shaded Dog pressings below.

Keep in mind that the stamper numbers you see belong to a different album.

The questions that audiophiles who collect shaded dog pressings should be asking themselves right about now are:

  • Why is 17s/20s consistently better sounding than any copy with any other stampers?
  • Why is the 16s pressing worse sounding than even the worst 17s pressing when they are both Indianapolis pressings only one digit apart?
  • Why does the 20s side two potentially win the shootout with a 3+ grade, but more often only earn a grade of 2.5+ or 2+?
  • And the hardest to stomach of them all are those second-rate 10s stampers. How on earth can they come in last in a shootout against all the copies with higher numbers?

It turns out that the old rule of thumb that the lower-numbered stampers will sound better than the higher-numbered ones is not nearly as reliable as some folks would like it to be.

If it were more reliable, we could all just buy the lowest-numbered stamper copies we could find and know that we had the best available pressing. Then, if we were lucky enough to encounter an even lower-numbered stamper copy, we could buy that one and know that we now had an even better sounding pressing, all without having to play the old “best” one against the new “best” one.

It’s so convenient and logical this way, why would anyone want to bother with a different illogical, inconvenient and obviously counterintuitive method when the other one has so much going for it?

There is only one problem with the idea of collecting the earliest shaded dog pressings in order to secure the best sounding pressings — the fact that the evidence to support such an approach is so spotty. Yes, early stampers win lots of shootouts. No, early stampers do not win all the shootouts, or even a majority of them, judging by a rough calculation using the data from the many hundreds of stamper sheets we’ve created over the years.

Predictions Are Futile

The unfortunate reality we run into is that most of the time we are not able to predict which stampers will win a shootout before we actually sit down to play all our copies.

Although it’s true that there are many pressings in which one set of stampers always wins, the odds are that any particular pressing with those stampers will do well but won’t win, and it sometimes happen that some pressings with those stampers won’t do well at all.

This is why we have to do shootouts, and why you have to do them too, if finding 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.

Out To Lunch on Liberty UA – “The Worst. So Metallic.”

Hot Stamper Pressings of Blue Note Albums Available Now

In our review for the White Hot Stamper shootout winner of Out to Lunch we played in 2023, we wrote:

Out To Lunch is finally back on the site after a four year hiatus, here with INCREDIBLE Shootout Winning Triple Plus (A+++) sound throughout this early pressing.

Dolphy’s debut for Blue Note is an absolute knockout musically, and the quality of the sound on this pressing was everything we could have hoped for.

Both of these sides are amazingly transparent, with stunning immediacy and exceptional clarity – thanks, RVG!

Bobby Hutcherson murders on the vibes on this album – hearing his stellar, groundbreaking work played back on a Top Shelf (3+/3+) copy through a high-end stereo is nothing less than a thrill.

Turn this one up good and loud and revel in the glory that is Out To Lunch, the man’s Masterpiece, and a Must Own jazz album from 1964.

However, if you made the mistake of buying a Black and Blue Liberty UA label pressing, the one that came out in 1970, what you heard bears absolutely no resemblance to the glorious sound we describe above.

Black & light blue label with Blue Note 70’s logo in a square on left, Liberty UA. Inc., Los Angeles, California text on bottom. Runout is etched apart from “VAN GELDER” and “STEREO” that is stamped.

Yes, it may have been mastered by RVG himself, but it sure doesn’t sound much like the better pressings of the album we played in our shootout.

You might think that if Rudy recorded it, he should have known how to master it, so why pay the big bucks for the originals when the man himself was still cutting Blue Note pressings as late as 1970.

Seems like a good rule of thumb to follow, but in this case, it turns out to be a badly mistaken one.

The Reissues Consistently Beat the Originals on this Mystery Mercury

Hot Stamper Pressings of Mercury Classical Records Available Now

For Mercury classical and orchestral recordings, the original FR pressings on the plum labels 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 originals we played read:

  • Tubey but never as open or dynamic as RFR-1 can be.

The better of the three FR pressings we played was not a bad sounding record, earning a grade of 2+. They’re just not as good sounding as the RFR reissues, which, of course, are the ones that win shootouts.

Something to keep in mind: A Super Hot Stamper Mercury orchestral record is guaranteed to be dramatically better than any Heavy Vinyl reissue ever made.

Are All the Original Asylum Pressings of Desperado Demo Discs?

Hot Stamper Pressings of the Music of The Eagles Available Now

No, and this should come as not much of a surprise to anyone that’s bought records from us or spent much time reading this blog.

As you can see from the notes below for this particular pressing of Desperado, both sides are passable, earning a minimal Hot Stamper grade of 1.5+.

It’s a decent sounding copy I suppose, but a long, long, long way from the best.

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 Desperado can be on the best vintage 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.


Desperado Is a True Super Disc 

Of course, the best sound on an Eagles record is found on the first album. For whatever reason, that record was left off the TAS super disc list, even though we feel that both musically and sonically it beats this one by a bit.

On the TAS Super Disc list. Harry Pearson recommends the British SYL pressings for this album. SYL pressings can sound very good; in fact, one of the top copies from a recent (2024) shootout was SYL. A bit of a surprise since our champion for both sides during the previous shootout was domestic.

Does that mean the best domestics will always beat the best SYL pressings? Not at all. Only critical listening can separate the superb pressings from the typical ones. After playing more than a dozen copies of this album this week, we can definitively tell you that there are far more mediocre copies of this record — both domestic and import — than truly exceptional ones. The typical pressing of this album, whether the domestic or SYL, falls far short of belonging on a Super disc list.

There are killer domestic copies and killer SYL imports out there, and the only way to know which ones sound good is to collect ’em, clean ’em, and play ’em.

Remember: TAS list doesn’t guarantee great sound, but Better Records does — if you don’t think a record sounds as good as we’ve stated, we’ll always happily take that record back and refund your money. Good luck getting ol’ Harry to send you a check when the TAS-approved pressings you pick up don’t deliver.

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 stampers for the pressing 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 Mystery 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.

Yes, For Some Records There Is Only One Set of Magic Stampers

Hot Stamper Pressings of Music on Island Records Available Now

As is sometimes the case, there is one and only one set of stamper numbers that consistently wins our Catch Bull at Four shootouts.

We stumbled upon an out-of-this-world copy of the right pressing in 2016, a copy took the recording to a level we had no idea could even be possible. (We were going to give it Four Pluses, and probably should have, but cooler heads prevailed.)

Since then we have had many copies come in, but none that could compete with the Magic Stamper pressings.

And the best part of this story is that, no, the best stampers are not 1U, or 2U, or even 3U.

As a matter of fact, they are far from the stampers found on the earliest pressings. That’s one reason it took us so long to discover them, because they are much less commonly found than pressings with the earlier stampers. By the time these later pressings were mastered, pressed and released, the album’s biggest selling days were over.

For all we know this cutting may have been done just to keep the record in print, possibly undertaken many years after its initial release.

Who knows? Who cares? What difference does it make?

Well, it does serve to make a point near and dear to our hearts: that the idea (and operational premise of most record collectors) that the originals are always better is just a load of bunk. It might be and it might not be.

If you want better sounding records, you had better open your mind to the idea that some reissues have the potential to sound better than even the best original pressings.

These, for starters, and there are hundreds more you can read about here on the blog.

Of course this is nothing but bad news for the average audiophile collector, who simply does not have the time or money to go through the hassle of buying, cleaning and playing every pressing he can get his hands on.

But good news for us, because we do.
