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!

Two samples from Money uploaded. One from the 20th anniversary edition, and then the suspicious one, a Japanese press -- the latter having positive ReplayGain.

They were ripped with dBpoweramp, which did not in version 13 log pre-emph. Since dBpoweramp does not (still not, AFAIK) subchannel, and from the Discogs information that there are indeed DSOTM pressings without the flag in TOC, I find it likely that the explanation is this is one such -- not that I simply overlooked the dBpoweramp screen; I cannot be sure, as they are stuffed away, so I cannot just find them and check with EAC. (Not all have jewel cases or booklets either, so might be hard to find ... what's $0.99 in the no-booklet bargain bin for another master of DSOTM?)


I have the following AccurateRip IDs (for CDDB ID, the last 8 chars):
009-000f7b7c-00728677-680a1009 for the Japanese (Speak to Me / Breathe in one track)
009-000f86f9-0072c558-710a1109 for the 20th anniversary (ditto)
010-000f950c-00823fc1-810a120a for the 30th anniversary (two tracks)

I also have a fourth one that turn out to have the same ID as the 20th anniversary. Likely a different pressing from the same master.

Just to point out the obvious.

The Japanese version has its spectrum significantly raised above about 2 KHz according to a CEP2 FFT analysis. Looks like premphasis.

Sounds that way, too.

Sure. But there are CDs which had the curve applied, but fail to have the flag set. Now the pinkfloydarchives seem to have checked it, though.
