    Hello!

    Dolby Prologic decodes two-channel sound to multichannel. How does it compare to SACD or DVD Audio?

    Which format is the best of SACD or DVD Audio? Who will win the format war?

    Dolby Prologic (II) decodes two-channel sound to multichannel. How does it compare to SACD or DVD Audio?

    That's like asking if Dolby Pro-Logic or Dolby Digital sounds better.

    First of all DPLII does not dekode anything from a plain stereo-source and thus can be seen as a kind of DSP mode. There are DPLII encoded soundtracks available, too, but you weren't asking about those. In any way it's still very different from e.g. Dolby Digital.
    Furthermore note that DPLII at best generates a 5.0 signal, i.e. no LFE or subwoofer channel like DVD-A and SACD.
    Both are discrete formats and thus beat DPLII hands-down in terms of channel separation and sound steering, not to mention the extended frequency range and higher sampling rate offered by DVD-A and SACD.
