WW, LW, JW? Which Stampers Sound the Best?

Hot Stamper Pressings of Rock and Pop Albums Available Now

UPDATE 2026

In 2005 we acquired more than a dozen sealed copies of a popular Warner Bros. title, how I don’t remember. (For now we are keeping that title, and even the band that recorded it, a mystery. It might have been The Doobie Brothers, but then again, it might not.)


Our story goes like this:

Knowing that no two of these pressings would sound exactly the same, we decided to crack them open, clean them up and play them.

2005 was very early in the development of Hot Stamper Shootouts. By 2007 we were much better at them, and not coincidentally, that is also the year we decided that Heavy Vinyl pressings were just not good enough for us to bother selling.

All three of the major stamper prefixes for Warners were represented in the various matrix numbers: WW, JW and LW. Once we started to play them it quickly became clear that most copies of this record just do not sound very good.

The typical copy is hard, midrangy, opaque, dull and badly lacks Tubey Magic.

Only one of the prefixes — WW, JW, LW — actually has any hope of sounding good, and surprisingly it’s not the one I would have expected it to be. Live and learn, right?


We liked either JW or WW back in 2005, I don’t remember which, but the evidence we compiled over the ensuing twenty years contradicted that finding.

Live and learn is right, because since the dark days of 2005, we have done this shootout many times, at least five by my count, and it turns out that the stampers we tend to like are exactly the ones we tend to like in general for Warner Bros.

Here is the full stamper sheet from a shootout we did not long ago laying out the stampers we like for this mystery title: LW, with low numbers.

James Taylor / Dad Loves His Work

More of the Music of James Taylor

  • This original Columbia pressing of JT’s 1981 release boasts incredible Shootout Winning sound
  • Both of these sides are exceptionally rich, Tubey Magical and spacious – thanks, Val Garay!
  • We were knocked out at how good this album sounds on a great pressing like this one – one of the more impressive 80s pop recordings we’ve played in some time
  • The sound may be heavily processed, but that kind of sound works surprisingly well on the highest quality pressings
  • 4 stars: “James Taylor bounced back from the spotty Flag with this all-original album led by his collaboration with J.D. Souther on ‘Her Town Too,’ his biggest pop hit since ‘Handy Man,’ and his biggest non-cover hit since his first, ‘Fire And Rain’…”
  • If you’re a fan of JT’s, or Folky Pop in general, this has to be seen as a top title from 1981.
  • We’ve recently compiled a list of records we think every audiophile should get to know better, along the lines of “the 1001 records you need to hear before you die,” but with less of an accent on morbidity and more on the joy these amazing audiophile-quality recordings can bring to your life. Dad Loves His Work is a good example of a record many audiophiles would benefit from knowing better.

The soundstage and depth on our best Hot Stamper copies is HUGE — this is without a doubt the most spacious recording by James Taylor we’ve ever heard. If you want your speakers to disappear, replaced by a huge studio full of musicians playing their hearts out, this is the album that can do it.

The Who – Who By Numbers

More of the Music of The Who

  • Who By Numbers returns to the site for only the second time in over three years, here with KILLER Shootout Winning Triple Plus (A+++) sound or close to it on both sides of this vintage Polydor import pressing – fairly quiet vinyl too
  • Glyn Johns‘s magic is on display here, with open mics in a big studio space creating the 3D soundscapes we love
  • Features two of their most iconic songs, “Slip Kid” and “Squeezebox,” and both sound incredible on this copy
  • 4 stars – Rolling Stone raves: “They may have made their greatest album in the face of [their personal problems]. But only time will tell.”
  • These are the stampers that always win our shootouts, and when you hear them you will know why – the sound is big, rich and clear like no other
  • We’ve discovered a number of titles in which one stamper always wins, and here are some others
  • If you’re a Who fan, this title from 1975 is surely a Must Own.

Dave Grusin – Discovered Again!

  • Grusin’s jazz Masterpiece from 1976 returns to the site for only the second time in sixteen months, here with INCREDIBLE Shootout Winning Triple Plus (A+++) grades or close to them throughout this original import copy – fairly quiet vinyl too
  • Here are just a few of things we had to say about this killer copy in our notes: “weighty, deep bass and kick”…”3D, rich, and silky”…”excellent detail and size”
  • After critically listening to this record good and loud, and hearing it sound the way this copy sounds, we have to call it One of the All Time Great Direct to Disc Recordings
  • The songs, the players, the arrangements, the sound – this is a record that will reward hundreds of plays for decades to come
  • Side one of this copy is out of polarity and not a copy you should buy if you can’t switch
  • “…makes for the kind of demo material audiophiles are so fond of using to impress friends and neighbors.”

We are on record as being big fans of this album. Unlike most Direct to Disc recordings, Discovered Again actually contains real music worth listening to. During our all-day shootout, the more we played the record, the more we appreciated it. These are top quality players totally in the groove on this material. When it’s played well, and the sound is as good as it is here, there’s nothing dated about this kind of jazz. Hey, what can we say — it works.

How Do the The Mastering Lab Pressings of Sticky Fingers Sound?

Hot Stamper Pressing of the Music of The Rolling Stones Available Now

A listing for an early domestic Hot Stamper pressing for Sticky Fingers will typically be introduced like this:

If you have never heard one of our Hot Stamper pressings of the album, you (probably) cannot begin to appreciate just how amazing the sound is.

A landmark Glyn Johns / Andy Johns recording, our favorite by the Stones, a Top 100 Title (of course) and 5 stars on Allmusic (ditto).

After hearing so much buzz about it, we finally broke down and ordered a German TML pressing about a year ago. Having played scores of phenomenally good sounding copies of the album over the past fifteen or so years, we were very skeptical that anyone could cut the record better than the mastering engineers who inscribed Rolling Stones Records into the dead wax on the early pressings. (I could find no mastering engineers credited.)

Well, the results were not good. As we suspected would be the case, we were not impressed in the least with what The Mastering Lab — one of the greatest independent cutting houses of all time, mind you — had wrought.

Their version is not really even good enough to charge money for. It might have earned a grade of One Plus, just under the threshold for a Hot Stamper that we would put on the site these days. Decent, but not much more than that.

Wait, There’s More

We subsequently learned that it is the British TML pressings that are supposed to be the best.

So we got one of those in, an A3/B4 copy.

Better, but good enough? Barely.

Here are the notes for the copy we played. For those who have trouble reading our writing, I have transcribed the notes as follows:

Side One

Track one:

Weighty, a bit veiled or smeary. Backing vox kinda lost.

Track three:

Very full, rockin’ but not the sparkle/space.

Kinda compressed.

Not as huge.

Side Two

Track two:

Not as rich, clear.

A bit pushy/dry vox.

No real space.

Thick drums

Track one:

This works better.

A bit hard, but full and lively.

This Sound?

Is this the sound audiophiles are raving about?

Judging the Sound of Heavy Vinyl We’ve Never Played

Hot Stamper Pressings of Pablo Recordings Available Now

We freely admit that we have never played the Heavy Vinyl pressing of The Alternate Blues on the Analogue Productions label. It started life in 1996 as APR 3010, part of the Analog Revival Series on 150 gram vinyl (average price on Discogs these days: $99), and now it seems to be in print on 180 gram vinyl, made from the same metalwork by the looks of it.

The mastering of the Analog Revival Series pressing may have been credited to Bruce Leek and Stan Ricker, but the stamper information is TML, The Mastering Lab all the way.

In case you, unlike us, are tempted to try one or both of the AP pressings, or perhaps already own one or both, here is our advice on how to recognize the fairly predictable shortcomings of Chad’s pressing, or any pressing mastered by Doug Sax in the 90s for that matter. Every one we’ve ever played has suffered from the same suite of sins.

The Best Part

And we expect that the AP pressing’s failures in some areas will be so obvious that you really don’t need any other copy of the album to be able to hear them.

Just focus on the two qualities that Analogue Productions’ records have always failed to deliver: transparency and freedom from smear.

In our 2011 shootout notes we drew the reader’s attention to both:

Little Feat – Waiting For Columbus

More Little Feat

  • A vintage copy of Waiting For Columbus with seriously good Double Plus (A++) grades or close to them on all FOUR sides – exceptionally quiet vinyl too
  • Some of the best sounding live rock and roll sound you will ever hear outside of a concert venue (particularly on sides one, two, and four)
  • If you want to understand the unique appeal of the band, there’s no better place to start than right here
  • One of our all-time favorite live recordings and their single best release – a true Masterpiece
  • 4 1/2 stars: “There’s much to savor on Waiting For Columbus, one of the great live albums of its era, thanks to rich performances that prove Little Feat were one of the great live bands of their time.”
  • We’ve recently compiled a list of records we think every audiophile should get to know better, along the lines of “the 1001 records you need to hear before you die,” but with less of an accent on morbidity and more on the joy these amazing audiophile-quality recordings can bring to your life. Waiting for Columbus is a good example of a record many audiophiles may not know well but should.

This is an amazingly well-recorded concert, and what’s more, the versions the band does of their earlier material are much better than the studio album versions of those same songs in every case.

Fat Man In A Bathtub on this album is out of this world, but you could easily say that about a dozen or more of the tracks on this double album. Which simply means that you will have a very hard time listening to any of the studio versions of these songs once you’ve heard them performed with the kind of energy, enthusiasm and technical virtuosity Little Feat brought to this live show. (I saw them twice with Lowell and they were amazing both times.)

This is some of the best sounding live rock and roll sound you will ever hear outside of a concert venue. In fact, on a great copy, it’s just about as good as live rock’n’roll sound gets.

Here is a link to take you to more letters, commentaries and reviews for Waiting for Columbus.

Lincoln Mayorga – The Missing Linc

More of the Music of Lincoln Mayorga

  • With two STUNNING Shootout Winning Triple Plus (A+++) sides, this Sheffield Direct to Disc recording is certainly as good a copy as we have ever heard
  • Guaranteed to be dramatically richer, fuller and more Tubey Magical than any other copy you have heard, with especially punchy drums and rosiny-textured strings
  • The bass on side one extends all the way into whomp land for that big bass drum at the end of “Limehouse Blues” – what a sound!
  • The top end is key to the better pressings too – lots of string harmonics and bells and other high frequency stuff gets lost on most pressings, but not this one, it’s all there on this pressing
  • The audiophile “Sgt. Pepper” of its day, a record that was so much better than anything else you’d ever heard it made you rethink the possibilities (and they did the same thing with Volume III two years later)
  • If you’re a Sheffield Labs fan, and what audiophile wouldn’t be?, this title from 1972 is clearly one of their best
  • If you’re a fan of big drums in a big room, with jump out of the speakers sound, this is the album for you.

This is definitely not your typical Sheffield pressing. Some of them are aggressive, many of them are dull and lack the spark of live music, some of them have wonky bass or are lacking in the lowest octave — they are prey to every fault that befalls other pressings.

Which shouldn’t be too surprising. Records are records. Pressing variations exist for every album ever made. If you haven’t noticed that yet, start playing multiple copies of the same album while listening carefully and critically.

Just listen to the texture on the saxophone on “Limehouse Blues” — you can really hear the leading edge transients of the brass that are so important to the sound of those instruments. Track after track, the sound gets surprisingly more open and airy. The harpsichord has such great presence it jumps out of the speakers. 

I was selling audio equipment (Audio Research, Fulton speakers) back in the ’70s and this was a favorite demo disc in our store. The bass drum at the end of track two would shake the foundation with a big speaker like the Fulton J.

Every bit as amazing to me was the string quartet on side 2. You could actually hear the musicians breathing and turning the pages on their music stands, just as if you were actually in their “living presence.”

This is one of the albums that made me realize how good audio in the home could really be. In a way this was the Audiophile “Sgt. Pepper” of its day, a record that was so much better than anything else you’d ever heard it made you rethink the possibilities.

Letter of the Week – “Why can’t all records sound this good…?”

Hot Stamper Pressings of the Music of Ambrosia Available Now

One of our good customers wrote to tell us about a very Hot Stamper pressing he purchased recently:

Hey Tom,   

Question:

Does Tom Port have any clue as to what the hell he’s doing or selling to the public?

That is my question.

Hello Tom,

I’m the idiot who spent $399 on your White Hot Stamper of Ambrosia’s first album a few weeks ago. I did an A/B listening test with an A++/A++ copy I bought from you a few years ago. Your website waxes lyrical about the exceptional qualities of this recording; I always thought it was very, very good but not quite the recording you make it out to be!

To perform my listing test, I listened to my A++/A++ side one first. Then listened to the newly purchased A+++/A+++ next. The results? I almost had to call 911 because my jaw hit the floor! THIS was the recording you had written about in the records descriptive comments. This pressing is so holographic I swear I could have stepped into the recording.

Dare I say this is a better recording than Dark Side of the Moon; and yes, I can make such a claim, I purchased an A++/A+++ – A++/A+++ copy from you guys a few years ago. This is what I refer to as Master Tape sound quality. A Holy Grail for audiophiles.

It’s pressings like this that pose the questions: Why can’t all records sound this good and why can’t all recording engineers be as great as Alan Parsons?

So, back to my original question. Does Tom Port know what the hell he is doing or selling to the public?

Yes Tom, I’d say absolutely, 100% you know what you are doing and I’m the happiest idiot on this Earth. Keep up the great work, Tom, and thank you and your staff for the incredible service you provide.

Todd N.

Dear Todd,

Thanks for your letter. I’m positively blushing!

Seriously, the right vintage pressing — on the right stereo — can take the enjoyment of music to a level far beyond that of anything being experienced by the audiophile of today, at least those who are stuck in a rut due to their misguided devotion to the modern Heavy Vinyl reissue. (more…)

Joan Baez / Diamonds and Rust

More Joan Baez

  • Boasting two incredible Nearly Triple Plus (A++ to A+++) sides, this early A&M pressing is practically as good a copy as we have ever heard, right up there with our Shootout Winner
  • The sound is rich, full, warm, and sweet, the vocals are full-bodied and breathy, and the acoustic guitars are fairly natural for a pop recording from 1975
  • Guaranteed to handily beat the Nautilus Half-Speed as well as the TAS list-approved MoFi (which is awful by the way)
  • These are the stampers that always win our shootouts, and when you hear them you will know why – the sound is big, rich and clear like no other
  • We’ve discovered a number of titles in which one stamper always wins, and here are some others
  • 5 stars: “…the real hit was the title track, a self-penned masterpiece and… her finest moment as a songwriter…”
