Reviews and commentaries for titles that were mastered at one of the greatest mastering houses of all time, The Mastering Lab.

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 any other digitally sourced material) that sounds as good as this record as long as 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 has passable sound, better than average but not really good enough for the serious audiophile. (More on our grading scale here.)

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.

Energy Is Key to the Best Copies of JT

Hot Stamper Pressings of the Music of James Taylor Available Now

The good copies really rock on songs like I Was Only Telling A Lie, yet have lovely transparent, delicate sound on the ballads Another Grey Morning or There We Are.

Just turn up the volume and play the opening to Honey Don’t Leave L.A. — this is James Taylor and his super-tight studio band at the peak of their powers. Russ Kunkel hits the drum twice, then clicks his sticks together so quickly you can hardly notice it, then goes back to the drums for the rest of the intro. On a superb copy like this one, the subtleties of his performance are clearly on display.

Until copies like this one came along, we had never even noticed that stick trick. Now it’s the high point of the whole intro.

Sound and Music

As audiophiles, we all know that sound and music are inseparable. In our shootout, after dropping the needle on a dozen or so copies, all originals by the way, we know when the music is working its magic and when it’s not.

As with any pop album, there are always some songs that sound better than others, but when you find yourself marvelling at how well-written and well-produced a song is, you know that the sound is doing what it’s supposed to do. It’s communicating the musical values of the material.

The most important of all these musical values is energy, and boy do the best copies of JT have it going on.

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.

Listening in Depth to JT

Hot Stamper Pressings of the Music of James Taylor Available Now

There are at least five or six James Taylor records that I would happily nominate as Desert Island Discs.

His albums set a standard that few other singer/songwriters’ albums can meet. Joni Mitchell comes to mind, and, like our friend James here, she explored many different styles of music throughout her career, the mark of a true artist.

After her, though, I would be hard pressed to name anyone with a body of work as extensive as Mr. Taylor’s.

And just to be clear, this would include all pop and rock artists from the 60s right through to the present. He is one of the greats in my book, and many of his albums are Must Owns.

And this is especially true for us audiophiles. The sound quality of the better pressings of most of his albums is consistently superior to the work of others from that time. Peter Asher deserves most of the credit for that.

Don’t try to start with the first album, which we can’t find for you because only the British pressings sound good and they are just too hard to find in clean condition [even though we did manage to do the shootout in 2022].

Instead go right to Sweet Baby James and JT.

The next group to pursue would contain Mud Slide Slim, Gorilla and In the Pocket.

Follow that up with One Man Dog and Dad Loves His Work (so underrated!).

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:

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…)

The Pareto Effect in Audio – The 80/20 Rule Is All Too Real

 

Basic Audio Advice — These Are the Fundamentals of Good Sound

Even thought this commentary was written close to twenty years ago, we proudly stand behind every word.

Ambrosia’s first album does exactly what a good Test Disc should do. It shows you what your system is doing wrong, or poorly, and once you’ve fixed it, or made it better, it shows you that it actually is better, maybe even right, or at least more right than it was before.

We audiophiles need records like this. They make us better listeners, and they force us to become better audio tweakers. Because the amount of tweaking you do with your setup, components, room, electricity and the like is the only thing that can take you to the highest levels of audio.

The unfortunate reality audiophiles must eventually come to grips with in their journey to higher quality sound is that you cannot simply buy equipment that will get you there.

You can only teach yourself, painstakingly, over the course of many, many years, how to tweak and tune your equipment — regardless of its cost or purported quality — in order to reach the highest levels of audio fidelity.

And learning how to tweak and tune your equipment has other, fundamentally more important benefits in addition to its original purpose.

It helps you become a better listener. To notice aspects of the sound — the nuances and subtleties — you’ve been missing in your favorite recordings.

Dream Weaver – A Good Test Record for Gritty, Grainy Sound

More Records that Are Good for Testing Grit and Grain

Most pressings of this album tend to err in one of two ways: either they’re a little bright and get hard and gritty in the upper mids, or they’re wrong in the opposite direction, with sound that is smeary and dull.

Our best copies get the balance right — plenty of texture on the keyboards and drums, with vocals that still have presence and breathiness — and not too much grit.

An all-keyboard pop record like this was a rarity at the time. The only other instruments besides drums (and one track with guitar) are keyboards. Every song is layered with multi-tracked clavinets, organs, and Moogs — it was a remarkable feat in 1975 to create an album with nothing but keys.

Listen to the title track, the most dynamic song on the record, and you will hear just how well all of those stacked keyboards and synths work together. (Steve Winwood’s Back in the High Life borrowed a page or two from Gary’s solo debut here.)

  • If you’re a Gary Wright fan, or perhaps a fan of mid-’70s synth-pop, this title, a personal favorite of mine from 1975, is surely a Must Own.
  • In our opinion, Dream Weaver is his best sounding album, and probably the only Gary Wright record you’ll ever need. Click on this link to see more titles we like to call one and done.
  • The sound may be too heavily processed for some, making it fairly difficult to reproduce, but the best sounding pressings, played at good, loud levels on big dynamic speakers in a large, heavily-treated room, are a fun listen. They sound just fine to us.
  • 1975 was a good year for music on vinyl — here are some excellent pressings of well-recorded albums available for purchase now.

Waiting For Columbus – We Broke Through in 2017

Hot Stamper Pressings of the Music of Little Feat Available Now

Way back in 2009 we had this to say about a Hot Stamper pressing we listed:

This German import pressing of Waiting for Columbus is much better sounding than the typical Mastering Lab-mastered copy.

This German pressing is similar to one that came from my own personal collection, accidentally discovered way back in the early ’80s as I recall. It KILLED my domestic original, and got some things right that even my treasured Mobile Fidelity pressing couldn’t. We have been meaning to do a shootout for this album for at least the last five years, but kept running into the fact that in a head to head shootout the right MoFi pressing — sloppy bass and all — was hard to beat.

This is no longer the case, courtesy of that same old laundry list you have no doubt seen on the site countless times: better equipment, tweaks, record cleaning, room treatments, et cetera, et cetera. Now the shortcomings of the MoFi are clear for all to see, and the strengths of the best non-Half-Speed mastered pressings are too, which simply means that playing the MoFi now is an excruciating experience.

All I can hear is what it does wrong.

I was so much happier with it when I didn’t know better.

That same laundry list of improvements continued to pay big dividends, and right around 2017 or so the best original domestic Mastering Lab copies started to sound much more right to us than the German ones.
