I haven't read the net chatter, but have seen the rather disappointing DR measurements for the CD. I hope the DR measurements are posted for the double vinyl soon after its release, and are higher, as that's the format I'm keen on buying.
Mike Fremer was present at Giles Martin's World of McIntosh Townhouse introduction to the 50th Anniversary release in late April and posted his thoughts, FWIW, some of which I've included below:
"Martin and Apple Corp. decided to produce a stereo re-mix that was true to the mono original, which was the mix in which The Beatles participated. The (original) stereo mix, produced by others, does not conform to what The Beatles intended in a number of ways, plus it takes creative liberties in areas like pans (the "fox hunt" for example).
Martin re-created the record in the high resolution digital domain, using original first generation multitrack elements that on the original had been mixed down a few generations on their way to being included in the final mix from four tracks. Martin's goal was to center vocals while generally remaining true to the mono mix, though in stereo. He also gave the bottom end some serious "wallop' that he claims was on the tapes.
Martin made use of all of the vintage gear originally used for the signature sonic manipulations and where appropriate, used tube-based compression (which is not the same thing as “smashing” the final mix).
There would be no need in 2017 for overall dynamic compression or bass attenuation, on either the digital or vinyl version and based upon hearing the album at The McIntosh Town House, the dynamics are full bore and the bass is muscular and not at all polite. Ringo’s drums sound explosively “right there”. Of course a cynic might say “Well the two living Beatles are out front, what a coincidence”, but I’m not a cynic."
Taking Fremer's account into consideration and looking at the results of the DR database, I'd have to conclude that subtleties in the original mono mix have been pushed more to the fore in the new stereo presentation, maybe so that no nuances escape the casual listener. Fremer's listening session was purely objective without any reference to measured DR and he seemed to like what he heard. Maybe some listeners will have their opinions biased by DR measurements rather than simply sit back, relax, and make an impartial assessment of the new stereo presentation. I'd assume that the new mix, with better stereo centering, will at least offer a different listening experience to the original stereo and some folks may well prefer it despite relative reductions in DR. The extreme channel separation of the vocals on the original stereo mix can be quite a distraction.
