The February/March 2016 issue of SOUND & VISION magazine, which is a champion for surround music, describes The Beatles 1+ 5.1 mixes:
"...all accompanied by stunning 5.1 mixes done by Giles Martin with Sam Okell at Abbey Road studios."
"There is no one else I'd trust to do The Beatles right in 5.1..."
"...."Strawberry Fields Forever" and "A Day in the Life" are fully realized in 5.1"
Hmmm, they liked it.
Check out the entire article toward the end of the issue.
These impressions of the release mirror my own observations from people OUTSIDE the forum community...I'm not surprised at all...
