    Maybe add a separate section at the bottom for releases that people suspect have missing PE tags or sound better with de-emphasis, I would rather not have them mixed in with the CD's that have confirmed PE flags.

    I'm not sure, I haven't checked. There is no other original CD release of Streetheart only a remaster and the Sabbath and BTO 2fers are unique to begin with aren't they? Bad Co. may have another original, but I'm not sure. There is sonic similarity to the BTO, W. German Greatest Hits that share some of the same tracks as the 2fer and the Black Sabbath 2fer sounds like the Japan for UK NELCD's which I'm 100% certain all have properly decoded PE before production. You know, it's a bit perplexing I'll agree, as to how they did get the PE set for the Japan 2fer of Black Sabbath S/T/ Paranoid and missed the boat on MOR/Vol. 4, but they did. As I say, try it out and you'll know for certain. The Bad Co. is really obvious when you compare the added PE version for comparison to the original cranked up.

    :agree: @shadowlord, even on my El Crappo® PC system you can hear the deemphed sounds much better with that killer shrillness gone.

    Agreed. I do not get the impression that any ripping software known to detect pre-emphasis flags in subcode is deficient. Rather, the disc may be deficient, a mastering mistake. But that still is only conjecture.

    In order to be a disc fully mastered with pre-emphasis, it has to meet two criteria:
    1. Pre-emphasis curve applied
    2. Pre-emphasis flags added
    If either or both are missing, a disc is not fully mastered with pre-emphasis -- be that intentional or unintentional. For example, some test CDs may contain tracks that have pre-emphasis curve applied but not flagged as such in order to demonstrate frequency response and phase shift effects of pre-emphasis. That is intentional.

    For the particular disc being discussed here, a real litmus test could be the analog output of a CD player known to conform to Red Book standards and always detect pre-emphasis flags. Does the disc play with de-emphasis curve applied?

    Now, for a video pun...

    This why I mentioned removal and can agree with its lacking qualifications even though the former is proven to be true.

    Just for clarity, I did not use the Foobar De-emphasis tool. I manually added the flags to the WAV file in Exact Audio Copy before burning a 1X CD-R. The SCD-1 has never missed a CD or a CD-R copy with pre-emphasis cues/flags on it and how I definitely confirmed audibly with playback comparison.

    The situation is very unique as I've tried to explain and I wasn't certain whether or not these "mistake masterings" should be included. You can also remove the Black Sabbath Master Of Reality/Vol. 4, BTO Not Fragile/Four Wheel Drive, and the U.S.A. Bad Co. Desolation Angels for the exact same reason even though it's been proven by listening comparisons to other CD pressings that do have PE present when it was mastered properly.

    I think "mistake masterings" should be included, but in a separate section. I just worry that it could get filled up with too many "someone thought it sounded better de-emphasised" entries, tough to come up with a good criteria since it is in many cases subjective.

    Loverboy - Keep It Up 35.8P -27 was mentioned earlier in the thread, but was never added to the list. No TOC PE with later EAC.

    I added DE (with SoX), and it sounds a bit dull, but I'm on the fence. Any definitive answers here?

    Update: After applying DE on all the songs, I sure think this belongs on the list. That said, it's only Loverboy, so no big deal... ;)

    So does mine, a Japan-for-US copy, but it has "35 8P" in the matrix. Confirmed with CueRipper.

    Hey hotsoup, thanks for the tip about CueRipper! I've installed it, and am able to identify many of the disks I was questioning.

    I've used EAC since FOREVER, but if they keep removing features, I might remove them... ;)

  12. I just checked my copy of Dire Straits - Alchemy for comparison. Both of my discs have pre-emphasis in the subcode and not in the TOC.
    My copy is a silver paint/red target Made in West Germany by Polygram. Matrix codes are:
    Disc 1: 818-244-2 02 G C L 9
    Disc 2: 818-245-2 01 DR (and a very faint "8A" or something else, on the inner ring on the opposite side from the rest of the matrix code)

  13. An interesting case is the Little River Band's "The Definitive Collection" CD from 2005. On it, the second track "Curiosity Killed The Cat" has a pre-emphasis flag on it (in the TOC) while the rest of the tracks do not. My guess is that maybe that track was sourced from a previous release containing PE, and the PE info was carried over, much like how HDCD-encoded tracks retain their info when ripped to WAV.

  14. Two more to add to the list:

    The Move - The Collection [Castle Communications CCSCD 135]
    Genesis - Wind & Wuthering [SONOPRESS CDSCD 4005/B-2309 A]

    I mentioned The Move CD in this thread back in 2011. The pre-emphasis is in the subcode on that disc, not in the TOC. My Denon player picks it up.
    The Genesis disc has been mentioned in a previous Genesis thread. I just wanted to confirm that the PE is in the TOC on that disc and that all CD players I have tried it on pick it up.

    That's great, I think it's much easier. I tried to find and install the last version of EAC that detected both kinds of PE flag but it didn't work well with my computer for some reason.

    Very strange as all those tracks are supposed to be new 2002 24-bit remasters.

  17. Just wanted to add that on this one, the PE is in the subcode, not the TOC.

  18. I want to clarify while this disc matches the info that is in the list (about both CDs having PE rather than just one), the disc packaging and catalog info is Warner Bros. 9 250852. The matrix of course corresponds to the Vertigo release (818...)

    Dire Straits - Alchemy - Dire Straits Live

    I got a copy and can confirm. Now, to figure out if it really has pre-emphasis or if it is just a flagging error.

    Another CD with a mix of tracks with and without pre-emphasis:

    LaserLight 14 010
    Holst: The Planets
    London Symphony / Geoffrey Simon

    Tracks 1-7 (Holst) with pre-emphasis
    Track 8 (Paganini: Intro. & Vars. on a Theme by Rossini) no pre-emphasis

    Checked with both dBpoweramp and EAC. This performance of The Planets has been on several cheap labels, so this is probably another case of "sourced from a previous release containing PE."

    yet another Japanese entry:

    S.Kiyotaka & Omega Tribe - Aqua City 1983 (VAP 80001-35, 1984 first CD edition)
    matrix: VAP-80001 2B6 59 (thus making this particular CD a repress from 1985)

    flagged in subcode only

    Previously I had posted here a 1989 ProJazz sampler, which had PE on most tracks. Now, two jazz CDs from same label just arrived, and I can confirm that both of them have PE, and flags in TOC

    Chi - Pacific Rim 1988 CDJ 677 (matrix MADE BY DISCOVERY SYSTEMS - AN AMERICAN COMPANY 3LX0300a)
    Oceans - Ridin' The Tide 1989 CDJ 697 (matrix MADE BY DISCTRONICS (H) W.O. 12888-1 CDJ697

    edit: just checked CDJ 677, like that sampler made by Discovery, also plays badly...

    Dunno if it was mentioned already but the 1990 CD pressing of Mercyful Fate's Melissa has pre-emph. Catalog number RRD9898 - pre-emph flag in the TOC.

    Thanks OT, that's a new one I believe, so it's probably safe to say earlier issues have it also
