A Tale of Two MoFi Deja Vu’s

Hot Stamper Pressings of the Music of Crosby, Stills, Nash and (Sometimes) Young

UPDATE 2026

A commentary from a long time ago about two different MoFi pressings of the same title, Deja Vu. We stopped playing Mobile Fidelity records like this a long time ago and the only ones we play these days are ones that are sent to us for free from customers or friends. Mobile Fidelity made some good records back in the old days. As I wrote not long ago, I owe them a debt of gratitude.

But the records we’ve auditioned that they’ve been making more recently had me asking: How is this company still in business?

Sonic Grade: F (or not!)

Just for fun about 10 years ago [make that 20] I pulled out a MoFi pressing of Deja Vu I had laying around. I hadn’t played their version in a long time. I could have gone a lot longer without playing it, because what I heard was pretty disappointing. Playing their record confirmed all my prejudices. The highs sizzled and spit. The heart of the midrange was recessed and sour.

Know what it reminded me of? A bad Japanese pressing.

(Since most of them are pretty bad I could have just said a typical Japanese pressing, but that’s another story for another day.)

And if that’s not bad enough, the bass definition disappeared. Bass notes and bass parts that were clearly audible and easily followed on our Hot Stamper copies were murky, ill-defined mud on the MoFi.

If you own the MoFi you owe it to yourself to hear a better sounding version. You really don’t know what you’re missing.

But Then, A Few Years Later We Played This Copy…

Here is what we had to say at the time:

Hot Stamper Sound on the MoFi pressing of Deja Vu, can it be possible? I have NEVER heard the MoFi sound this good, not even close. This just KILLS the other copies I’ve heard. I wrote a scathing review of their badly mastered pressing which you can read below, and I still stand behind every word, because this copy is not your average MoFi. The average one still sucks. What we are selling here is a FLUKE. Here is the story from our Hot Stamper shootout we just did.

This week we picked up a very clean looking MoFi pressing and decided to throw it in the shootout just for fun. We were shocked — this one actually sounded good! Not as amazing as our best Hot Stampers, but much better than we had expected. We checked our old copy and heard the same bad sound described above. 

Pressing variations exist for audiophile records as well, and here was another example. It just goes to show that nothing short of playing a record will tell you how it sounds — except for reading our website. Who besides us could spend so much time playing so many bad records? It’s a dirty job, but we’re happy to do it. Hearing one amazing record makes up for playing 10 bad ones, so we’ll keep at it.

Keep in mind that the only way you can never be wrong about your records is to simply avoid playing them. If you have better equipment than you did, say, five or ten years ago, try playing some of your MoFi’s, 180 gram LPs, Japanese pressings, 45 RPM remasters and the like. You might be in for quite a shock.

It’s all good — until the needle hits the groove. Then you might find yourself in need of actual Better Records, not the ones you just hoped were better.

James Taylor – Sweet Baby James

More of the Music of James Taylor

  • An early Green Label pressing with seriously good sound for this inarguable JT Masterpiece, earning solid Double Plus (A++) grades or close to them on both sides
  • All that lovely echo is a dead giveaway that side one of this pressing has resolution far beyond that of the others you may have heard (and of course the Rhino Heavy Vinyl), and side two is not far behind in all those areas
  • Richness and body and Tubey Magic are every bit as important – when those big choruses kick in, you want the sound of all those singers to be as big as life without the strain that accompanies their voices on so many copies
  • Finding early pressings without marks or groove damage is no mean feat these days, but here’s one to prove it can be done
  • Top 100 and 5 stars: “Sweet Baby James launched not only Taylor’s career as a pop superstar but also the entire singer/songwriter movement of the early 70s that included Joni Mitchell, Carole King, Jackson Browne, Cat Stevens, and others…”
  • If you’re a James Taylor fan — and what audiophile wouldn’t be? — this title is clearly one of the best albums released in 1970 and a true Must Own for the singer-songwriter-loving audiophile

Vocal reproduction is key to the better sounding copies of Sweet Baby James, as it is on so many singer-songwriter albums from the era.

To find a copy where Taylor’s vocals are front and center — which is exactly where they should be — but still rich, sweet, tonally correct and Tubey Magical is no mean feat. Only the better copies manage to pull it off.

Out of the dozen or more Green Label early pressings we play every year, relatively few have the full complement of Midrange Magic we know the best copies can have. As a rule of thumb, the hotter the stamper, the better the vocal reproduction on that copy.

Sibilance Can Be a Bitch (and a Good Test for Table Setup Too)

Hot Stamper Pressings of the Music of 10cc Available Now

On side two the tonal balance is key. If there is any boost to the top end, the vocals on track two will SPIT LIKE CRAZY.

This is also a good test for how well your cartridge and arm are doing their jobs. Sibilance is a bitch. The best pressings, with the most extension up top and the least amount of aggressive grit and grain mixed into the sound, played using the best front ends, will keep it to a minimum. VTA, tracking weight, azimuth and anti-skate adjustments are critical to reducing the spit in your records.

We discuss the sibilance problems of MoFi records all over the site. Have you ever read Word One about this problem elsewhere? Of course not. Audiophiles and audiophile reviewers just seem to put up with these problems, or ignore them, or — even worse — simply fail to recognize them at all.

Play around with your table setup for a few hours and you will no doubt be able to reduce the sibilance problems on your favorite test and demo discs. All your other records will thank you for it too. 

This record, along with the others linked below, is good for testing the following qualities.

  1. Grit and grain
  2. Sibilance (it’s a bitch) 

Playing so many records day in and day out means that we wear out our Dynavector 17DX cartridges often, about every three to four months.

Which requires us to regularly mount a new cartridge in our Triplanar.

Once broken in (50 hours min.), we then proceed to the fine setup work required to get it to sound its best, adjusting the VTA, azimuth and tracking weight for maximum fidelity.

Sibilance Is a Bitch on Nick Of Time

Hot Stamper Pressings of the Music of Bonnie Raitt Available Now

We here present some advice on what to listen for to help you separate the best pressings of some of our favorite rock and pop records from those that are merely good.

On side two listen for the sibilance on Bonnie’s voice on Too Soon to Tell.

Some copies have gritty, spitty sibilance on her voice, while others keep the spit well under control, allowing much more of the silky quality of her vocal to be heard.

Sibilance is a great test for pressings that you may be comparing for sound quality. Sibilant pressings tend to be crudely mastered and that crude quality is sure to show up in other areas of the recording.

(Half-Speed mastered pressings are almost always spitty and should be avoided, for their sibilance problems as well as their many other often serious shortcomings, which we have documented in detail all over this blog.)

Also, pay special attention to how silky the cymbal crashes can be on the better copies.

We also recommend that you listen for how all the elements of the recording are clearly laid out and audible, never forced or hyped in any way. The sound can be surprisingly 3-D for a modern recording.

When Did You First Hear that 10k Boost on Sittin’ In?

Hot Stamper Pressings of the Music of Loggins and Messina Available Now

UPDATE 2026

It took us a long time to recognize it, I can tell you that. 30 years? Maybe even more.

And how about the boost to the low end?

This commentary is from many years ago, perhaps as far back as 2010.

Of course it could not have been written until the stereo had reached the level where these anomalies and others like them could be easily recognized, the clearest kind of evidence of progress in audio.

If you’re not noticing these kinds of things on the vintage vinyl you play, then it’s probably time for a serious upgrade or two.

The anomalies are there, of that there can be no doubt. They’re everywhere. You just need a more accurate and revealing system and room to show them to you.

In that respect, you my find our shootout notes are helpful at pointing you in the right direction as to what you should be listening for. They are especially helpful in recognizing when one side or another falls short in some specific area.

We Don’t Offer Domestic Pressings of Pour Down Like Silver for One Very Simple Reason

Hot Stamper Pressings of the Music of Richard Thompson Available Now

In spite of the fact that the domestic pressings of this Richard and Linda Thompson classic from 1974 were mastered by the likes of Kendun and Sterling — two of the greatest mastering houses of all time, — they have never impressed us with their sound quality.

The biggest problems with this record would be obvious to even the casual listener: gritty, spitty vocals; lack of richness; bright tonality; lack of bass; no real space or transparency, etc.

The domestic Island pressings did not do nearly as well in our shootout as the best Island imports, no surprise there as the early UK records were mastered by one of our favorite engineers.

Avoid the Carthage pressings mastered by Sterling. They came in last in our shootout.

The domestic breakdown follows:

Does Year of the Cat on Mobile Fidelity Have Audiophile Sound?

Hot Stamper Pressings of the Music of Al Stewart Available Now

Our answer, judging by the copy we played not long ago, would be solidly in the negative. The final grade we awarded both sides was No, our way of saying the record is Not Good.

Below is a description for what a top copy of the album sounds like, based on our most recent shootout:

Incredible sound throughout this vintage Janus pressing of Stewart’s 1976 Masterpiece. With engineering by Alan Parsons, the top pressings are every bit the audiophile Demo Discs you remember. The best sides have sweet vocals, huge amounts of space, breathtaking transparency, and so much more.

Tubey Magical acoustic guitar reproduction is superb on the better copies of this recording. Simply phenomenal amounts of Tubey Magic can be heard on every strum, along with richness, body and harmonic coherency that have all but disappeared from modern recordings (and especially from modern remasterings).

But if you own the wrong Mobile Fidelity pressing — this one was reissued in 1981, the original came out in 1978, so there may be some other pressings that sound better than this one — you would never know how good sounding the album can be. We put a copy we had laying around in a shootout recently and the results were, not to put too fine a point on it, pretty painful.

As the notes make clear, the Mobile Fidelity pressing, with the stampers you see on the sheet above, is:

Michael Jackson / Thriller – A Rock, Pop and Soul Masterpiece

More of the Music of Michael Jackson

  • With solid Double Plus (A++) grades from top to bottom, we guarantee you’ve never heard Michael Jackson’s Masterpiece of hard rockin’ funky pop sound this good – exceptionally quiet vinyl too
  • The sound is huge – big, wide, deep, and open, with a punchy bottom end and rhythmic energy to spare, as well as cleaner, smoother, sweeter upper mids and a more extended top
  • A Top 100 title and 5 stars on AMG: “This was a record that had something for everybody, building on the basic blueprint of Off the Wall by adding harder funk, hard rock, softer ballads, and smoother soul — expanding the approach to have something for every audience.”
  • In our estimation, there are about 40 Must Own rock, pop and soul records from the 80s, and if there’s any album that belongs on that list, it’s Thriller
  • There is a version cut at Half-Speed by Mobile Fidelity, and as you can imagine, we did not much care for it

This is some of the best High-Production-Value rock/pop/soul music of the 80s. The amount of effort that went into the recording of Thriller is comparable to that expended by the engineers and producers of bands like Supertramp, The Who, Jethro Tull, Ambrosia, Pink Floyd and far too many others of our favorites to list. It seems that no effort or cost was spared in making the home listening experience as compelling as the recording technology of the day permitted.

Sound that came lumping-out-of-the-speakers coupled with driving rhythmic energy were the hallmarks of the best copies. These qualities really brought this complex music to life, gave it room to breathe, and made it possible for us to enjoy the hell out of it. This is yet another definition of a Hot Stamper — it’s the copy that lets the music work as music. (more…)

Please Please Me on MoFi – Another Disgracefully Spitty Half-Speed

Hot Stamper Pressings of the Music of The Beatles Available Now

Sonic Grade: C

If you own the Mobile Fidelity LP, do yourself a favor and buy one of our Hot Stamper pressings. (Actually any good British import pressing will do.)

What’s the first thing you will notice other than correct tonality, better bass and a lot more “life” overall?

No spit!

As we’ve commented elsewhere, because of the wacky cutting system they used, Mobile Fidelity pressings are full of sibilance. 

As I was playing a British pressing of this record many years ago, maybe by about the fifth or sixth song it occurred to me that I hadn’t been hearing the spit that I was used to from my MoFi LP. You don’t notice it when it’s not there.

But your MoFi sure has a bad case of spitty vocals. If you never noticed them before, you will now.

We discuss the sibilance problems of MoFi records all the time. Have you ever read Word One about this problem elsewhere? Of course not.

Audiophiles and audiophile reviewers just seem to put up with these problems, or ignore them, or — even worse — fail to recognize them at all.

Play around with your table setup for a few hours and you will no doubt be able to reduce the severity of the sibilance on your favorite test and demo discs. All your other records will thank you for it too.

Especially your Beatles records. Many Beatles pressings are spitty, and the MoFi Beatles pressings are REALLY spitty. Of course MoFi fans never seem to notice this fact. Critical listening skills and a collection of MoFi pressings are rarely if ever found together. For reasons that should be obvious to anyone spending time on this site, you either have one or the other.

Here’s How You Know You Have a Hot Stamper of Songs in the Attic

joelsongs600Hot Stamper Pressings of the Music of Billy Joel Available Now

It’s the side you play through to the end.

When the sound is right you want to hear more.

Since the opening track of this record is one of the keys to knowing whether it’s mastered and pressed properly, once you get past the sibilance hurdle on track one, the next step is to find out how the challenges presented by the rest of the tracks are handled on any given pressing. Some advice follows.

Actually, what you really want to know is how good each song can sound — what it sounds like when it’s right.

Once the quality of the mastering has been established, the fun part is to play the rest of the album, to hear it really come alive.

Side One

Miami 2017

This is usually the brightest cut on the first side, commonly found with some sibilance problems. On the high-res copies the sibilance is lessened, and the sound of the sibilance itself is much less transistory and spitty, with more of a silky quality, which is simply another way of saying it’s less distorted.

Of course one wouldn’t want the sibilance to be lessened by having a dull top end, but few of these pressings are dull. Most of them suffer from a brightness problem. The best copies keep the sibilance under control and balance the upper mids with extended highs. Without extension on the highs the sound will tend to be aggressive.
