    This is the description of some new re-released CD's that i bought from Japan:
    SHM-CD :
    New Japanese editions, very limited and often sold out even before the date of issue of the print!
    Superb new SHM-CD (Super High Material CD) format produced by JVC and Universal Music Japan.
    They used plastic polycarbonate with a pure transparency to improve the sound quality.
    The disc has excellent sound quality compared with American or European press.

    Now my question is:
    If i rip the audio from these new CD's and then convert them to MP3's for my ipod or just make some identical full wave quality copies to burn on blank CD's etc..... will the sound quality still be as good.
    I'm asking this because, it sounds like all the audio benefit from buying these new type of compact disc's is in the actual Super high material itself and not in the actual recording.
    So if i remove the digital information from the CD and burn it to an inferior blank disc as a 1:1 straight copy...then common sense tells me i will lose some of the sound quality. I hope this doesn't sound too confusing.
    I would appreciate any thought's.
    Thanks.

    Often referred to as a SMAM-CD. Overpriced nonsense.

    Those discs are created for an audiophile market that increasingly seems to have less and less sense. The manufacturers would certainly like you to think that their discs are a superior solution for sound, but I would bet that if you were to take 10 random people and test these discs with their "normal" CD counterparts that nobody could tell the difference. Just for the heck of it a few years ago I bought two of JVC's XRCD discs. THese were the predecessor to SHM-CD that used regular CD material in the discs. The story was that JVC used higher quality mastering than with "normal" CDs and the sound was superior. I found them to be a big waste of the extra money as they don't sound any better to me than normal CDs.

    This is internal manufacturers' technology improvement in process stability, etc. Consumer shouldn't notice any difference from usual properly made CD's (with correction of digital errors using the standard built-in error-correction code). It's pure promotion trick that those CDs got special name, unlike with HDCD's which actually provide better resolution parameters (bit-depth equivalent of 20 bit). That SHM label is not even provided with any specially good audio mastering (from what I've listened to) to prove those CDs sound better than usual CDs. In comparison, most HDCD's are well mastered and technology there emphasizes good work of audio engineers like Steve Hoffman.
