Whilst the 2017 Pepper has more clarity than the 2009 mono, the bass is too heavy. The mono sounds more natural to me.
The comparison is between two mono editions. One from the 2009 CD box set and the other from the 2017 Pepper box.
So I guess it would dilute the purpose and subject of this thread... to ask where the 2014 mono analog vinyl fits into all of this. So I won't ask where the 2014 mono analog vinyl fits into all of this. Because that would be apples and oranges. Yes, let's stick to digital CD comparisons.
Another observation: The 2009 Mono CD utilises the full 22.050khz CD Audio spectrum, while the 2017 CD stops at 21.8 "ish". Though most of the additional hz are from dithering noise, there is actually a small amount of actual audio information lost on the 2017 CD. So from that standpoint, the 2009 CD is a clear winner without discussion. *click*
It's not audible so that ultrasonic content isn't reponsible for it sounding any better or worse. It's within the pale of reason that a very small number of specimens of the human race could possibly hear 21kHz tones, but I seriously doubt any human's hearing goes up to 22kHz.
I'm talking about the mono. The mono cd that comes in the Pepper Box. The direct transfer of the original mono mix.
I'm saying I choose the 2017 mono because it is the version the Beatles liked the most. No EQ, limiting, compression blah blah blah
There are many factors that could lead to variation in dynamic range that has nothing to do with compression. Unless it's in the single digits, one can't jump right to compression as the reason.
