It's now possible to compare the 2014 remaster and the 50th anniversary on spotify. Even on my computer speakers, the differences are fairly obvious. The The 50th A. features more up-front vocals and at first, an refreshing overall impression of clarity. I say "impression", because I became increasingly aware that drums and bass have also been accentuated which, to my ears, makes for muddy lower mids despite a relative improvement in clarity up top. This muddiness is something certain youtube reviewrers have complained about. Harrison was not that strong of a vocalist and I actually prefer the 2014 version, where his voice sits more in the mix, rather than standing out. Ironically, I found the 2014 more emotionally engaging. Of course, others will hear differerently.
