Luckyjackson1 has gone into more detail than anyone else so far on the specifics of this set.
I am going to begin transferring his observations to this post.
I will line through those that are matters of opinion or purely qualitative observations. There are a few things here that may eventually fall into that category, but may require further testing.
I will italicize items that already are dealt with in the original post in this thread.
Items that are in bold are issues I'm focusing on at the moment.
The “Love Me Tender” session sounds really clear now, fantastic improved sound!
Did they probably take “Let Me” from scratch and use the audio track and Elvis’ vocal overdub to combine them a-new?
Finally the intro of “How’s The World Treating You” doesn’t sound like it’s been spliced anymore (right before Elvis starts singing).
There are drop-outs on the ending of “Got A Lot O’ Livin’ To Do!”
It’s funny because “One Night” sounds like it has been no-noised. I have no proof for that. Just a thought because there's virtually no tape-hiss audible to my ears. Immediately after that follows “True Love”, which has a whole lot of tape hiss on it. Did the engineers back then also use noise reduction? Probably during the process of copying the master on a different reel?
“Surrender” sounds marvelous!
The Splice on “In My Father’s House (Are Many Mansions)” sounds a little sloppy, as the spliced part comes in a split second too fast.
I never heard “In My Way” in such a fantastic sound quality!
There’s a drop-out on the first drum-hit of “Steppin’ Out Of Line”, Elvis’ voice is still overdriven.
I never cared too much for “I Met Her Today” but here the sound is simply astonishing. A crystal clear beauty!
Unfortunately the edited tracks from the “Kid Galahad”-soundtrack have been released again in its edited form. It makes perfect sense as the unedited versions were released for the first time in 1993. I never before heard Elvis humming along on the intro of “Home Is Where The Heart Is”!
“She’s Not You” is slightly clipped on the beginning but the strange sound on 2:05 is still audible (finger snap or creaky bone ?).
Strange, but they also used the short stereo version of “Mama”.
“Dainty Little Moonbeams” still leads into the finale of “Girls! Girls! Girls!”
Finally they corrected the splice on “Plantation Rock”.
But compared to “I Don’t Wanna Be Tied” (the previous track), it sounds unbelievably flat!
Listen to the right channel on the intro of “Marguerita” - the acoustic guitar is clearly audible.
The intro to “Spring Fever” is slightly clipped, therefore the Jordanaires sing “pring fever”.
The intro to “Scratch My Back (Then I’ll Scratch Yours)” is still clipped, but hey, who cares?
“Down In The Alley” has the correct intro without missing any drumbeat.
The error on the intro of “Fools Fall In Love” has been corrected.
“I’ll Remember You” is the original edited version.
“I’ll Take Love” still has the bad splicing job close to the end.
“Sing You Children” has an sloppy, amateurish fade-out job, it fades out with a lot of echo and then there’s a sound that reminds me of a skipping record… ???
The drum hit on the ending of “Clambake” is stil there (was missing on the “Double Features” and restored for the FTD).
The strange reverb on “Let Yourself Go” (Version 1) is finally gone again.
“High Heel Sneakers” is the originally edited version.
“You Don't Know Me (Record Version)” has the fixed ending.
“Stay Away” has the longer fade-out.
“Wonderful World” and “Edge Of Reality” have the original fade-outs.
“A Little Less Conversation” is the single version (Take 16) with the longer fade-out.
“Swing Down Sweet Chariot” (Version 2) is unfortunately the overdubbed version - one more reason to keep the “Double Features” CD that contains the original undubbed version.
“Signs Of The Zodiac” has a lot of (additional?) echo. So what…?
“Mama Liked The Roses” has the longest fade-out.
“My Little Friend” is the remixed version as used first on the “Almost In Love”-LP.
“In The Ghetto” has the original fade-out.
“Rubberneckin’” is the remixed version as used first on the “Almost In Love”-LP.
“Without Love (There Is Nothing)” has a slight early fade.
“I'll Hold You In My Heart (Till I Can Hold You In My Arms)” has a rather bad “intro-job”.
“Suspicious Minds” fades again at 4:19.
“Any Day Now” still has the strange “distant” sound.
Unfortunately, "America" and "Softly, As I Leave You" sound like they did on their first release (which makes perfect sense, considering the main reason for this release). Even the badly edited applause is there!
"I Need You So" never sounded better.
"Guitar Man" is the regular faded version,
but it sounds flawless, speed is corrected compared to the 60's Box.
The original mixes from the "Frankie And Johnny"-Soundtrack were used on this release
and have been improved, just like the "Harum Scarum" soundtrack. I prefer the Double Features mixes although the mastering is obsolete now.
The “On Stage” album has the original mix (including screams on “Polk Salad Annie” etc.)
“Little Cabin On The Hill” has a different intro (the first few bars).
Sounds a little odd to me.
"Bridge Over Troubled Water" has the overdubbed applause on the end.
“Faded Love” is the unedited master.
“I Washed My Hands In Muddy Water” is the (nearly complete) unedited master.
The right channel on "Where Did They Go, Lord" sounds kinda dull.
“Whole Lotta Shakin’ Goin’ On” sounds strange to my ears - I don’t know how to describe this but I get the feelin’ of a constant “bright- and dullness" (also again on the right channel)...
Unfortunately, a big minus: The intro of "Rags To Riches" is f***ed up again... this time even worse than before.
The right channel again sounds kinda dull to me here. I think the best version is still the one found on the german CD "The Collection, Vol. 4" (not sure right now if it's the same as found on "Elvis Aaron Presley", aka the "Silver Box).
"Padre" is most likely the so-called "Original Alternate Mix" they used on the recent "FOOL"-FTD and on the Franklin Mint Set.
“Merry Christmas, Baby” has a digital error (or whatever it is) audible at 0:05 - didn’t hear such thing since an old CD back in the 90’s…
“My Way” again has the bad sounding echo on Elvis’ voice like on its first release on the 70’s Box.
So it clearly sounds better on the new “FOOL”-FTD (that means: buy it!). Again this raises the question if L.R. is responsible for all 103 “rarities”…
The sound quality on "I'll Be Home On Christmas Day" (remake) is nowhere nearly as good as on the masters released during Elvis' lifetime, what probably confirms my fears regarding the "rarities".
“Where Do I Go From Here” has the last faded note on 2:36.
Haven't checked out, what mix of "Fool" they used here...
It seems that the speed on the MSG has been corrected, as it sounds fine with me.
This has been mentioned zillion times before but let me remark once more that this show needs a remixing desperately. Nevertheless it never sounded better than here. And unlike on the 90’s CD, the strange error (repeated snippet) on “The Impossible Dream” is gone again, thank god!
“Aloha From Hawaii” sounds rather dull to me, otherwise quite powerful.
I think they used some no-noise on the Aloha bonus tracks for they contained some really bad hiss. Compared to the recent "FOOL"-FTD they sound about the same.
Now we know how the masters on the (someday) upcoming “Promised Land”-FTD will sound like: wonderful, glorious! Never heard a better quality of these December ’73 recordings.
Update: A sad note: The intro of "Promised Land" is cut. Never heard such a bad job on that intro before. Another big minus! I hope this is going to be corrected on the FTD for that album.
Probably the most important detection: "My Boy" is thank god the version with the spliced ending, therefore it's the longest running take available!!!
I must say I prefer the vintage mix of the original “Live On Stage In Memphis” album better than on the recent FTD, except for the fake applause, of course. Once more, please! But here the overall sound is quite satisfying (although I recall that I listened to a better sounding CD in the past, probably the 24-bit version).
The whole “Today” album sounds marvelous, better than on all previous releases (except for probably the original vinyl LP which I haven’t heard).
Even Elvis' voice on "Bringing It Back" sounds pretty decent now.
The jam of “Tiger Man” is faded very quickly. Sounds like the same mix as on the 70’s Box and/or the “Today”-FTD (dunno for sure if they were equal).
Elvis’ voice on “It’s Easy For You” sounds more natural now. Beatiful! The keyboards sound a little disturbing because they are way too upfront for my taste.
The dog barking on the very end of “Way Down” is back again!
"Long Legged Girl (With The Short Dress On)" is NOT clipped.
"Guitar Man" is the same as on the recent "Clambake" AND "Elvis 75" escape/release.
How's the sound on the second LP (Elvis) when compared to Kevan's remaster? I think they sound punchier and the EQ is lower compared to Kevan's remaster. Sounds almost no-noised but I guess they are not.
Xmas songs, do they sound better? Compared to the 50's Box, yes. I don't like the tampering they did on the "White Christmas" intro. Also punchier and lower EQ.
what about the june  masters, any improvement? They still sound kinda distorted and probably have been recorded that way. Wouldn't really call it improvement. I just think it can't get much better than this.
Flaming Star songs (other than the main title), how they sound compared to double features?
"Summer Kisses, Winter Tears" sounds really clear. "Britches" doesn't have the really bad, annoying echo/reverb anymore. "A Cane And A High Starched Collar" also sounds crystal clear. Guitar left, accordion right and Elvis centered. I just wonder why the fizzy "s" is clearly audible again on "Flaming Star" ???
It happened at the world's fair, anything remarkable? Hell, yeah. The (digital?) crackling sound on every intro (as on the "Double Features") is gone. Didn't compare it to the FTD though.
Here they sound full and warm. Even "How Would You Like To Be" has "drive"!
those spinout tracks...how they sound? Didn't compare them but I guess they are no real improvement compared to the FTD. Might sound a little brighter and punchier. IIRC, the LP sounded better.
How's the intro of Honky tonk angel? I think the intro is slightly clipped and of course it's still distorted at 0:07.
Also TALK ABOUT THE GOOD TIMES - Is it a longer fade out or the abrupt one? [frus75 chimes in:] Talk is the short version. [and luckyjackson1 confirms:] Exactly, my friend. Just like "Carny Town".
So [Talk About the Good Times] fades off abruptly just like when it first was released on GOOD TIMES ? Yes, as it was originally released on March 20, 1974.
Somebody wrote that the "Roustabout" tracks sound worse here. They actually sound punchier and with lower EQ.
I must say the whole ["Roustabout"] soundtrack (except for "There's A Brand New Day On The Horizon") has a lot of (unnatural? additional added?) echo... hmmm, mysterious! To me the echo sounds like on the first "Girl Happy"-FTD escape. Or even worse, like the annoying 90's computer reverb...
"Hard Knocks" has a slight drop-out at 0:03 on the left channel, while at the same time on the right you can hear somebody's voice or whatever this is... strange!
I don't know, I haven't listened to my 80's LP pressing [of Roustabout] for a long time. Can anybody confirm that there was a lot of echo on the original album???
