How can I tell if my version of DSOTM was mastered with pre-emphasis?

Per http://www.hydrogenaudio.org/forums/index....st&p=810470, I looked at my CD of Dark Side of the Moon, and looked at the tedious but uninsightful discussion at http://www.stevehoffman.tv/forums/showthread.php?t=264920 , and still can't definitively determine if my CD has pre-emphasis or not. Any advice appreciated!

My CD is labelled on the top as:
Stereo
CDP 7 46001 2
DIDX 226
Made in the U.S.A.
Manufactured for Capital Records, Inc.
1973 The Gramaphone Company Limited
1973 Capital Records, Inc.

Around the inner ring on the top:
DIDX 226 111A6

Around the innermost ring on the top:
Made in USA - Digital Audio Disc Corp.

On the back of the CD case, upper right:
CDP
7 46001 2
DIDX 226
Barcode 0 777-46001-2

Cover of the booklet has the pyramid and prism spectrum graphic, and in the upper right a circle around "Pink Floyd the Dark Side of the Moon"

On the back of the booklet, upper right:
CDP
7 46001 2
DIDX 226

I bought it new in the 1980's for what it's worth. I used dBpoweramp to rip it and it did not detect pre-emphasis. The images shown on the first link above on discogs are exactly as on my CD, with two exceptions:

- my CD has DIDX 226 on the inner ring of the disc itself which discogs specifically precludes from the version it is defining.
- the outlined section on the left of the top of the CD image on discogs shows a second row of just "Made in the U.S.A.", while my version has "DIDX 226 | Made in U.S.A."

moderator: please add "version" after "my" in the thread title - thanks!

Even most of the 80s CDs didn't have pre-emphasis. IIRC, it was only the "black triangle" releases from Japan that were pre-emphasized (unless I'm getting it mixed up with the Beatles' releases).

In any case, the digital table of contents on the disc itself has a Pre-Emphasis flag that is either turned on or off. It's been a long time since I've ripped a CD, but I recall EAC being able to detect if this flag was set, and I suppose dbPowerAmp does the same. If it says your CD is not pre-emph, then it isn't.

See http://pinkfloydarchives.com/DUSCDPF.htm#DSOTM ... you have one of the Sony US masterings ("5th" or "6th" issue), which do not have pre-emphasis.

The one on Discogs is mine; it's a Sony Japan mastering ("4th" issue), which does have pre-emphasis.

For DSOTM, it is the Sony Japan masterings that have pre-emphasis. These were distributed worldwide; in my case, there's nothing on the disc other than "TO J" in the matrix to indicate that it's actually from Japan. The pinkfloydarchives.com link above has all the details.
