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.

It Took Us Until 2012 to Finally Beat the Audiophile Pressing We Swore By

Hot Stamper Pressings of the Music of Supertramp Available Now

UPDATED 2026

We have not had very good luck with domestic pressings of this album for quite a few years now. The German pressings are also not very good, earning at most 1.5+ and more often than not a lower grade. (Hey, we had to be sure.)

The Canadian audiophile pressings are comparable, 1.5+ or close to it, not good enough to bother with when the right UK pressings are so much better.

The listing below is from 2012. Since that time we have been able to find and play a great many British pressings of the album, and they always win our shootouts now.

But the domestic pressings can also do very well, just not well enough to win shootouts these days, a clear case of live and learn.

Our Understanding from 2012

TWO AMAZING SIDES, including an A+++ SIDE ONE! It’s not the A&M Half Speed, and it’s not a British pressing either. It’s domestic folks, your standard plain-as-day A&M pressing, and we’re as shocked as you are. Hearing this copy (as well as an amazing Brit; they can be every bit as good, in their own way of course) was a THRILL, a thrill that’s a step up in “thrillingness” over our previous favorite pressing, the A&M Half Speed.

Breezin’ – “Hot Stamper” MoFi Reviewed

Hot Stamper Pressings of the Music of George Benson Available Now

UPDATE 2026

Having heard so many good sounding copies of this album, it is unlikely we would find much to like on the MoFi. But we can’t deny that we did, a long time ago, after cleaning and playing three MoFi copies, two of which were awful.

Sonic Grade: B-

Another MoFi reviewed, and surprisingly this one isn’t awful.

It has an excellent side two backed with a pretty good side one.

Side two has excellent bass — for a MoFi — and lots of energy — for a MoFi.

It’s slightly smooth, but overall it’s very musical. The best domestic copies are going to eat its lunch, but try to find one that sounds good. Most of them are awful. 

This MoFi copy, though lacking in many ways, is much better sounding than the other MoFi copies we played it against, which were muddy and compressed.

Side one of this copy has some of that sound. Side one lacks the transients we found on other copies and it’s a tad recessed and compressed. However, it does have relatively good bass definition and the strings are nicely textured.

The Nautilus Half-Speed of Harvest Is Not Bad!

Hot Stamper Pressings of the Music of Neil Young Available Now

Sonic Grade: B

We haven’t played a copy of this record in more than a decade [make that two], but back in the day we liked it, so let’s call it a “B” with the caveat that the older the review, the more likely we are to see things differently now. 

In the early 2000s we wrote the following (please excuse the all-caps, I could barely type back then):

This is a SURPRISINGLY good sounding Nautilus Half-Speed mastered LP with AMAZING transparency.

The sound here is DRAMATICALLY more natural than your average audiophile pressing. Just listen to the phony top end found on most MoFis to see what we mean.

On this record you’ll hear none of the hyped-up highs that are MoFi’s claim to fame.

This Nautilus is sure to destroy the typical domestic pressing, which (before cleaning) will tend to sound opaque, thick and dull.

This Half-Speed wouldn’t really match up to our Hottest Stampers, but you could sure do a lot worse.

Although it’s a tad fat at the bottom, it still retains much of the warmth and richness found on the best copies.

In the Court of the Crimson King – A Surprisingly Good Pressing from Mobile Fidelity

Hot Stamper Pressings of Progressive Rock Albums Available Now

The MoFi pressing shown here is surely one of their best.

Unfortunately, these days we have little tolerance for the dynamic compression, overall lifelessness and wonky bass heard on practically every record they ever mastered. Including this one.

One of the reasons your MoFi might not sound bad to you is that it isn’t really “wrong” the way most Mobile Fidelity pressings are. It’s doing most things right, and it will probably beat most of what you can find to throw at it. 

It’s lacking some important qualities, and a listen to one of our Hot Stampers will allow you to hear exactly what you’re not getting when you play an audiophile pressing, any audiophile pressing, even one as good as MoFi’s.

Side by side the comparison will surely be striking. How much energy, size, power and passion is missing from the record you own?

There’s only one way to find out, and it’s by playing a better copy of the album.  (more…)

Are All MoFis Created Equal? A Pair of Pink Floyd LPs Proved They Aren’t

Hot Stamper Pressings of the Music of Pink Floyd Available Now

[This commentary was written about twenty years ago.]

Many audiophiles are operating under the misapprehension that Mobile Fidelity managed to eliminate pressing variations of the kind we discuss endlessly on the site.

That is simply not the case, and it’s child’s play to demonstrate how misguided this way of thinking is, assuming you have the following four things: good cleaning fluids and a machine, multiple copies of the same record, a reasonably revealing stereo, and two working ears.

With all four the reality of pressing variations for ALL pressings is both obvious and incontrovertible.

The discussion below of a Hot Stamper pair of Dark Sides from long ago may shed light on some of the issues involved.

Remember Classic Records Comparison Packages?

This is our first Hot Stamper Comparison Package.

For those who remember the 45 RPM/ 33 RPM Classic Records comparison packages, this is somewhat in the same vein. Of course, we don’t know that they kept the EQ the same for the 45 versions compared to the 33s of the albums included in the package, so the comparison is suspect at best.

You’re not really comparing apples to apples unless you keep the EQ exactly the same. I rather doubt they did, because on Simon and Garfunkel the sound was noticeably worse at 45 than it was at 33. This is the main reason we don’t carry the 45 versions of Classic’s records: they are a lot more money, and who knows if they’re even any better?

[This one sure wasn’t better. This guy liked it, but he is rarely right about any of this record and equipment stuff, as I hope everyone knows by now.]

Imagine on MoFi Heavy Vinyl from 2003

Hot Stamper Pressings of the Music of John Lennon Available Now

Sonic Grade: B

The last time I played this record was probably in the mid-2000s. Not sure what I would think of it now. Probably not much. Back in those days we thought it was a reasonably good sounding pressing, but it’s doubtful we had ever heard an exceptionally good version of the album, as it would be years before we managed to do our first shootout for it. To see what we have to say about the record now, please click here.

Our review from many years ago:

I played this when it came out, and I have to hand it to the new MOFI, they did a great job with this one. It sounds better than I’ve ever heard it, and KILLS the old MoFi vinyl, which is the version we did the shootout with.

It was a short comparison, as in, no comparison. The earlier MoFi Half Speed (a different master tape, but still…) has that classic MoFi midrange suckout this awful label is famous for, so that Lennon and his piano on the first track sound like they are coming from another room.

Super Session – A Jack Hunt Mastered MoFi Winner

Hot Stamper Pressings of Music Produced or Performed by Al Kooper Available Now

Sonic Grade: B

Super Session is one of the best-sounding MoFi pressings. The midrange sounds wonderful — silky sweet and transparent. Not having been cut by Stan Ricker, the top end doesn’t have that SR/2 boost. Overall it’s a very nice sounding record, and the music just can’t be beat. 

In fact, it was actually mastered by Jack Hunt, a man we know to be responsible for some of the thickest, dullest, deadest MoFi recuts found in their shameful catalog.

But he did a pretty good job on this one, and for that he deserves some credit.

We Used to Really Like The Forward Look on UHQR

Audiophile Records with Honest-to-Goodness Top Quality Sound

Hot Stamper Pressings of Live Jazz Recordings Available Now

This is a very old review, probably from 2010 or thereabouts.

Hard to say what we would think of this pressing today, what with our unwavering antipathy to Half Speed mastering. In the case of this record, you can add the consistently poor track record of the so-called UHQR to our list of reasons for suspecting that the quality would not in fact by Ultra High.

You are no doubt aware that the UHQR was recently brought back from the dead by Analogue Productions on a pressing whose packaging is quite a bit more impressive than its sound.

Our Old Review

This is a BRAND NEW UNPLAYED Reference 45 RPM Half-Speed Mastered UHQR LP. They only made 1,000 of these, so sealed or unplayed copies are virtually non-existent.

This is actually one of the best sounding Reference Records. It was recorded in the ’50s on location and has very natural sound. Half-Speed Mastered by Jack Hunt even!

I think the exceptionally natural sound found on this record is the result of two factors:

  1. It’s a live recording, meaning not everything can be controlled and the space is real, not engineered. And,
  2. This is early days in the recording history of Keith Johnson. As time went on he thought his engineering skills were improving, but I see little evidence of that in the results of his labors: the records he’s been making since 1957.

His records are as phony and weird as practically every other audiophile label of the day (M&K, Telarc, Chesky), no doubt the result of these audiophile types thinking they knew a lot more about recording music than turned out to be the case.

Play any vintage pressing from the ’50s to see exactly what they failed to accomplish.

We know of at least two releases on Reference Records with “astoundingly” bad sound.

Both figure prominently on our list of the worst kind of audiophile bullshit records.

Joan Baez on Nautilus – The Half-Speed that Beats Most Pressings

Hot Stamper Pressings of the Music of Joan Baez Available Now

Sonic Grade: B+

This review is from many years ago, at least ten I would think, so take it for what it’s worth.

One of the best Half Speed mastered records we have ever played.

In our recent shootout we were shocked — shocked — to hear how good our old copy of Diamonds and Rust on Nautilus sounded head to head against some of the best pressings we could find.

If I hadn’t heard it with my own two ears, I wouldn’t have believed it.  (more…)
