    Maybe a dumb question, but I'm not sure what a SACD is. Do you need a special player for them? Is the sound quality that much better than regular cd's?

    check the beginner's FAQ (in the ht basics forum). there's a good article in there about SACD & DVD-A.
    in a nutshell, these formats offer two main benefits.
    1. higher resolution music - you hear "more" of the music
    2. multi-channel music - different instruments/voices can be "steered" to different channels (front, rear, etc.)
    otherwise, just ask lee scoggins about sacd or john kotches about dvd-a - that is when they're not yelling at eachother. [​IMG]

    Thanks Ted,

    From what I have read, it sounds to me like it is surround sound. So I would assume you need at least five speakers to totally appreciate it?

    Peter, SACD offers both high-resolution stereo and surround sound. All SACDs are encoded with a high-resolution stereo track. Some also have a high-resolution surround-sound track, which is usually encoded in 5.1. 5.1 is the maximum speaker configuration found on surround-sound SACD tracks, but the tracks can be encoded with fewer channels. For example, the surround-sound track on the Mike Oldfield Tubular Bells SACD is encoded in 4.0, as it is the original Quad mix.

    Below are the various forms of SACDs. You will see stickers on the front of SACD jewel cases with these notations.

    Single-layer Stereo: The disc simply has a stereo SACD track.

    Single-layer Multi-channel: The disc has both stereo and multi-channel (surround-sound) SACD tracks. Only multi-channel is mentioned in this notation since stereo is implied. All SACDs have a stereo SACD track.

    Hybrid Stereo: The disc has two separate layers. One layer has a CD layer that can be played in most any CD player. The second layer has a stereo SACD track.

    Hybrid Multi-channel: The disc has a CD layer and then has both stereo and multi-channel SACD tracks.

    Sony SACDs and some SACDs from Universal Music Group are single-layer stereo or single-layer multi-channel discs. Universal has also released some hybrid SACDs. SACDs from other labels are either hybrid stereo or hybrid multi-channel discs.

    Peter, one more thing to note. The Rolling Stones remastered discs in cardboard digipaks that you can find in the CD section of any music store are actually hybrid stereo SACDs. There is no mention of SACD capability on the outside packaging, but it is mentioned inside the digipak.

    Actually it stands for “Super Audio Compact Disc” I don’t think anyone mentioned that.

    It's 'something' that kisses the master tape.
