“…this BR copy just lifted the veil.”

Hot Stamper Pressings of the Music of Pink Floyd Available Now

One of our good customers had a few things to say about a Hot Stamper pressing of Meddle he purchased recently, which turned out to have the same stampers as the copy he already owned.

He had no way of knowing what the stampers of our copy were when he ordered it of course. It no doubt came as a surprise, but thankfully Michel did not judge the record we sent him by the stamper numbers. No, he judged it the way it should have been judged, by the sound.

In this case the sound was clearly superior to the copy he had even though the stampers of the two records were identical. (If you would like to see more examples of this phenomenon, we have plenty here. It actually happens all the time. It’s so common that we rarely bother to make blog posts about it. Years ago we wrote a piece about it expressing our views on the subject.)

Hi Tom,

Just a quick note about Meddle WHS. I also had an A!/B! XXX which does sound pretty good and is quiet, but this BR copy just lifted the veil.

Once I dialed in the sweet spot it was a delightful experience. This copy is the bomb!!

Many Thanks,
Michel

Michel,

Not all A!/B!’s are created equal!

Most copies of the album with the right stampers will earn a grade of Super Hot, A++.

Some will be White Hot, A+++.

Almost all the pressings we play will have the same stamper numbers, although you may have read that we did just find another stamper for side two that can win shootouts.

Some of the difference in sound is the result of our using The Prelude Record Cleaning System, in conjunction with the Odyssey record cleaning machine we purchased in 2007 (more on that here).

Clean records sound better than they uncleaned records, and properly cleaned records often sound much better than they otherwise would, oftentimes a full grade better.

Before and After Science – Rules Are Made to Be Broken

Hot Stamper Pressings of Art Rock Recordings Available Now

The domestic pressings of Before And After Science are typically grainy, low-rez and hard sounding. But that doesn’t mean our best Hot Stamper pressings are imports.

No. The best pressings are made right here in the good old U.S. of A.

Say what? Yes, it’s true. We were SHOCKED to find such Hot Stamper sound lurking in the grooves of a domestic Eno LP. It’s the only one of its kind. In thirty plus years of record playing I can’t think of any domestic Eno LP that ever sounded this good.

Now hold on just a minute. The British pressings of Eno’s albums are always the best, aren’t they?

For the first three albums, absolutely. But rules were made to be broken. This pressing has the knockout sound we associate with the best British originals of Eno’s albums, not the flat, cardboardy qualities of the typical domestic reissue.

The UK pressings we have played have always been awful. We put one in a shootout in 2025 and it was as awful as we remember it. Our notes read:

  • Very lean and dry.
  • Zero bass!
  • Lousy!

And Here I Thought The Mastering Lab Made Nothing But Good Sounding Records

Hot Stamper Pressings of the Music of Ambrosia Available Now

We just did a shootout for Ambrosia’s One Eighty album, describing our Shootout Winning copy this way:

Analog at its Tubey Magical finest. You’ll never play a CD (or other digitally sourced material) that sounds as good as this record no matter how long you live.  This is smooth, rich analog at its best, easy on the ears as we like to say.

But none of what we said about our best Hot Stamper pressings would apply to the copies with the stampers you see below.

One of the copies we played with JW1 stampers was good, not great, earning a barely-hot 1.5+ grade. 1.5+ is four grades down from the best. That’s a steep dropoff as far as we’re concerned. 1.5+ only hints at how good a recording One Eighty can be on the best pressings.

The other pressing with those stampers did not qualify as a Hot Stamper at all. We would say it had passable sound, better than average but not really good enough for the serious audiophiles we cater to.

Had it not been cleaned to make it quieter and improve its sound quality, it most likely would not have earned that single plus at all. In that respect it would have much in common with the kinds of LPs filling up the shelves of record collectors everywhere. Who needs another mediocre sounding record sitting on the shelf? And yet there they are.*

Our two best sounding copies were cut at The Mastering Lab and had exactly the same stampers. Like a lot of Warner Bros. records, JW (Jacksonville) pressings rarely sound as good as those pressed elsewhere. (You record experts out there will know what the other plants are.)

What Good Is Knowing that 2-1B/2-1G Wins Shootouts?

Hot Stamper Pressings of the Music of Neil Young Available Now

Especially considering the fact that the best copy (3/3) with those stampers earned significantly better grades than the worst copy with those stampers (1.5/1.5)*.

Does anyone have a practical way to get around the confusing and exasperating reality that one set of stampers can sound great and the same or a similar set of stampers can sound not much better than passable? Take a spin and see where the wheel of fortune stops.

To be honest, we can’t say there is a practical way to get around these mysteries, but we do know of an impractical one. We’ve been practicing and refining the impractical one we came up with twenty years ago and, according to our customers, it works like gangbusters.

Turns out that all you have to do  is just play lots and lots of different copies of albums and they will tell you how they sound.

In the case of the record you see below, the copies with the best stampers and the copies with some of the worst stampers had the same stampers.

Here is the full stamper sheet for a shootout we did recently.

Note that the album you see pictured 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.

Everybody Knows that 1s Should Beat 2s Should Beat 3s, Right?

Hot Stamper Pressings of Living Stereo Recordings Available Now

In the case of this mystery Living Stereo title, the conventional wisdom holding that the original first pressings (1s) will most likely have sound superior to the higher-numbered pressings (2s) turns out to be right.

Below you will see the complete stamper sheet for a shootout we did recently. Note that the album you see pictured is not the record we did the shootout for.

We are not revealing what record 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.

Sometimes we do though. To see the titles whose Shootout Winning stampers have been revealed, please click here. The list we’ve compiled to date is short but more are coming.

The sound of 3s with the Red Label was lean and dry on both the copies we played. This was surprising as the stampers are quite low: 3s/3s.

Many RCA chamber recordings can be dry, and if one owned a nice early stamper pressing of the album with lean, dry sound, one might conclude that this RCA is just another chamber recording with those shortcomings.

But one would be wrong, because the 1s stamper Shootout Winner sounded amazing, not dry or lean in the least.

Soultrane – Supposedly Reprocessed into Stereo, But Was It Really?

More of the Music of John Coltrane

It may say stereo on the cover, but this album is pure, glorious MONO, with sound that is full-bodied, relaxed, Tubey Magical and tonally correct.

This is a mono recording that has supposedly been reprocessed into stereo. Rudy Van Gelder did the mastering, and my guess is he decided to leave the sound mono and simply not tell anyone. Who can blame him? He engineered it in mono, so why fix what ain’t broke just because the label decided to print the cover and the label with the word “stereo” in order to generate more sales?

We’re lucky he did. The early OJC reissues of this title are awful, and whatever Heavy Vinyl they’re churning out these days is probably every bit as bad.

Allow Us to Make the Case that Even CDs Have Better Sound than Classic’s Vinyl

brahmvioli_1903_debunk

Hot Stamper Classical and Orchestral Pressings Available Now

The Classic reissue of LSC 1903 is a disaster: shrill, smeary and profoundly unmusical.

In these four words we can describe the sound of the average Classic Records Living Stereo pressing.

The best Heifetz records on Classic were, if memory serves, LSC 2734 (Glazunov), LSC 2603 (Bruch) and LSC 2769 (Rozsa).

They aren’t nearly as offensive as the others, and one is actually quite good. If you can pick one up for ten or twenty bucks, you might get your money’s worth depending, I suppose, on how critically you listen to your classical records.

The CDs are better for all I know. That’s probably the first place to go, considering Classic’s generally poor track record.

Shootout Winning Stampers for the Scythian Suite Revealed

Hot Stamper Pressings of Orchestral Spectaculars Available Now

When it comes to the Scythian Suite, we’ve decided that there is no good reason to put the Ansermet recordings in our shootouts anymore.

Don’t get me wrong. They are perfectly good records, but the Abbado is a step up both in performance and sound. Our main listening guy summed up the differences of the two recordings this way.

  • I prefer the DG version (2530 967) for sound and performance.
  • The London is very rich and lively but the big drums on the DG are killer, hard to beat!

So, out of the goodness of our hearts, we can now reveal the Shootout Winning stampers: 1W/1W.

However, in the case of CS-6538, knowing the right stampers is not going to get you very far.

You will actually need a pile of copies with those stampers in order to find one worthy of a 3+ White Hot stamper grade.

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 were hoping for. To do that you have to clean and play at least six copies the way we did.

A Kinder, Gentler Approach to Record Reviewing

Record Collecting for Audiophiles from A to Z

Allow me to respond to a comment left by a fellow named Ian Malone.

It was left in the comments section for the interview Steve Westman did with me.

He wrote:

Quite happy for you to promote your business Tom, but surely you are a better person than doing it in this way. I know that other people in the industry have said unkind things about you but you can rise above these insults.

My response:

I never say that the people making these modern records, as well as those reviewing them, are malicious or evil. I say they make or review bad sounding records and are simply misguided and, more than anything else, incompetent.

Am I being unkind? If Michael Bay makes one bad movie after another, are we unkind to point that out? I don’t know whether or not he is a bad person, but I do know that he is a bad filmmaker, and gets called out regularly for putting out a bad product.

Everyone understands that this is a matter of taste. If you always wished The Beatles albums had more bass, more compression and a smoother tonal balance overall, you can buy the new Heavy Vinyl pressings and get the sound you prefer on every title The Beatles ever released.

However, I hope you know that the sound I have just described does not exist on the master tapes.

UPDATE 2026

I would amend the above statement to say “that the sound I have just described is very unlikely to exist on the master tapes,” since all of the pressings of The Beatles’ music that we think sound more correct do not have that sound. Where that “more correct” sound came from is a matter of speculation, but we sure know it when we hear it, as do our customers. More on that subject here.

I have no way of actually knowing that for a fact, but since no mastering engineer before 2014 had ever put that sound on an actual record, I think we can safely say that the evidence supports the idea that a completely “new sound” was specifically created for The Beatles when their catalog was remastered early in this century.

Strawberry Studios Dropped the Ball When They Mastered This One

Hot Stamper Pressings of Elvis Costello’s Albums Available Now

We described a Shootout Winning Hot Stamper pressing of Armed Forces we listed not long ago this way:

This vintage UK pressing will show you just how good sounding Elvis’s best recording can be, with a KILLER Shootout Winning Triple Plus (A+++) side two mated to a solid Double Plus (A++) side one.

It’s some of the biggest, boldest rock sound ever recorded. A Top 100 Demo Disc – every track is Elvis at his best.

Armed Forces is one of the best-sounding rock records ever made, and a copy like this is proof enough to back up that claim. The better copies are extremely transparent and silky sounding, but with unbelievably punchy, rock-solid bass and drums.

I would say the sound of the rhythm section of this album ranks up there with the very best ever recorded. Beyond that, the musical chops of this band at this time rank with the very best in the history of rock. Steve, Bruce and Pete rarely get the credit they deserve for being one of the tightest, liveliest backing bands ever to walk into a studio or on to a stage.

All true, if you happen to be playing the right UK pressing. The ones with Strawberry in the dead wax on side one, however, are not remotely competitive with the best pressings we played in our last shootout, as you can easily see from the stamper sheet below.

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 Armed Forces can be on the best vintage pressings.
