The Most Serious Fault of the Typical Half-Speed Mastered LP?

Hot Stamper Pressings of Revolver Available Now

UPDATE 2026

This commentary must be fairly old because we haven’t bothered to play anything put out by Sundazed in longer than I can remember.


The most serious fault of the typical Half-Speed mastered LP is not incorrect tonality or poor bass definition, although you will have a hard time finding one that doesn’t suffer from both.

It’s dead-as-a-doornail sound, plain and simple.

And most Heavy Vinyl pressings coming down the pike these days are as guilty of this sin as their audiophile forerunners from the 70s. The average Sundazed record I throw on my turntable sounds like it’s playing in another room. What audiophile in his right mind could possibly find that quality appealing? (Apparently the guy who wrote this absurd list of records you should buy It has a number of inexcusably at best mediocre and mostly awful sounding Sundazed records.)

But Sundazed and other companies just like them keep turning out this crap. Somebody must be buying it.

So how does the famous MoFi pressing of Revolver sound? In a word, clean. Also not as crude as the average British import, and far better than any Japanese or domestic pressing we heard.

But it’s dead, man. It’s just so dead.

The current record holder for Most Compressed Mobile Fidelity Record of All Time? This shockingly bad sounding release, a record I admit to owning and liking back in the 80s. I had a lot of very expensive equipment back then, but it sure wasn’t helping me recognize how bad some of my records were.

How many audiophiles are where I used to be? Based on what I read on audiophile forums, and the kinds of audiophile pressings I see discussed on youtube videos, it seems that most of them are.


In practically every Hot Stamper listing on the site you will find some standard boilerplate that looks very much like what you see below. These are the qualities we want our records to have. I cannot begin to understand what audiophiles are listening for on these new reissues. Most of them do practically nothing well.

This is not AI-generated. This is copy and paste.

What We’re Listening For on Revolver

  • Energy for starters. What could be more important than the life of the music?
  • Then: presence and immediacy. The vocals aren’t “back there” somewhere, lost in the mix. They’re front and center where any recording engineer worth his salt — Geoff Emerick in this case, and it’s his first album with the boys as Chief Engineer — would have put them.
  • The Big Sound comes next — wall to wall, lots of depth, huge space, three-dimensionality, all that sort of thing.
  • Then transient information — fast, clear, sharp attacks, not the smear and thickness so common to these LPs.
  • Tight punchy bass — which ties in with good transient information, also the issue of frequency extension further down.
  • Next: transparency — the quality that allows you to hear deep into the soundfield, showing you the space and air around all the instruments.
  • Extend the top and bottom and voila, you have The Real Thing — an honest to goodness Hot Stamper.

This group gets a regular workout too:

What the Best Sides of Revolver Have to Offer is Not Hard to Hear

  • The biggest, most immediate staging in the largest acoustic space
  • The most Tubey Magic, without which you have almost nothing. CDs give you clean and clear. Only the best vintage vinyl pressings offer the kind of Tubey Magic that was on the tapes in 1966
  • Tight, note-like, rich, full-bodied bass, with the correct amount of weight down low
  • Natural tonality in the midrange — with all the instruments having the correct timbre
  • Transparency and resolution, critical to hearing into the three-dimensional studio space

No doubt there’s more but we hope that should do for now. Playing the record is the only way to hear all of the qualities we discuss above, and playing the best pressings against a pile of other copies under rigorously controlled conditions is the only way to find a pressing that sounds as good as this one does.

If you are buying these modern pressings, take the advice of some of our customers and stop throwing your money away on Heavy Vinyl and Half-Speed masters.

At the very least let us send you a Hot Stamper pressing — of any album you choose — that can show you what is wrong with your copy. And if for some reason you disagree that our record sounds better than yours, we will happily give you all your money back and wish you the best.

People have been known to ask us:

How come you guys don’t like Half-Speed Mastered records?

That’s an easy one. We’ve played them by the hundreds over the years, and we’ve found that as our ability to reproduce the sound of these records improved (better equipment, table setup, tweaks, room treatments, electricity and the like), the gap between the better non-Half-Speed mastered pressings and the Half-Speeds got bigger and bigger, leaving the Half-Speeds further and further behind, in the dust you might say, again and again, with so few exceptions that they could easily be counted on the fingers of one hand.

We’ve been playing Half-Speed mastered records since I bought my first Mobile Fidelity in 1978 or 1979. That’s forty years of experience with the sonic characteristics of this mastering approach, an approach we have found to have consistent shortcomings.

These shortcomings have somehow eluded the devotees of these records, how, we cannot imagine.

(That’s really not true, of course. Fans of Half-Speed mastered records are as clueless as I was when I was just starting out. Many of the records I used to swear by were Half-Speeds.

With almost no exceptions, my failure to recognize what they were doing falls under the general heading of live and learn.)

Eventually we came to understand them better, and we since have laid out their faults, chapter and verse, in the 140+ reviews we’ve written on this blog to date.

The dozen or so commentaries found here are a good way to get a taste of what we’ve learned.

  1. If you think the Mofi Revolver is dead sounding, wrap your ears around any of the Beatles 50th Anniversary releases by reknowned tin-ear Giles Martin or the work of fellow deaf person Miles Showell, current chief half-speed apologist. Regards, Mike.

    1. It’s shocking how bad these new records are. We’ve reviewed Abbey Road and Revolver, two of the worst sounding Half-Speed mastered records ever made, but somehow those in the audiophile press seem to find them much less abhorrent than you and I do. Apparently a tin ear is good for job security, especially in the audiophile reviewing game. An excerpt from my review for Revolver:

      In 2020 I had reviewed the Abbey Road remix and was astonished that anyone would release a record of such utter sonic worthlessness. A few choice lines:

      The half-speed mastered remixed Abbey Road has to be one of the worst sounding Beatles records we have ever had the displeasure to play.

      Hard to imagine you could make Abbey Road sound any worse. It’s absolutely disgraceful.

      I will be writing more about its specific shortcomings down the road, but for now let this serve as a warning that you are throwing your money away if you buy this newly remixed LP.

      Of course I never did write more about it. The thought of listening critically to the album in order to detail its manifold shortcomings was more than I could bear and onto the back burner the idea went, where it remains to this day.

      In 2020 I warned the audiophile community not to go down this foolish half-speed mastered road, and now that they have been kicked in the head a second time, perhaps when they wake up they will come to their senses, although I doubt very much that they will.

      Giles Martin is the guilty party here, and I hope it is clear by now that he simply has no clue as to how a Beatles record should sound. If he did have such a clue, this new Revolver would never have seen the light of day.

      Thanks for writing,

      TP
