SACD is better than DVD-A.

Why do I say that? Well, the answer is really simple. More resolution horizontally (timewise). First of all, DSD, the format used by SACDs, can accurately represent frequencies of up to 100 kHz, even in multichannel mode. DVD-A format is primarily either PCM or Dolby Digital and only has its highest frequency response in 2-channel stereo, where its sampling rate is 192 kHz, allowing for frequencies only as high as, say, 90 kHz before response drops off dramatically. If 5.1-channel multichannel mode is used, that drops down to about 45 kHz. And news flash: stereo and multichannel never appear on the same audio DVD, so the stereo listener is at the mercy of the mixdown algorithm in the player. So much for DVD-A. SACD, on the other hand, has enough room and processor power to handle 6 channels of audio up to 100 kHz plus a premixed stereo downmix, also up to 100 kHz. You may not need to hear sounds that high, but it’s sure nice to know they’re there!
