[[Image:Sacd.svg|right|frame|How a hybrid Super Audio CD works]]
The biggest competition to DualDisc was the hybrid [[Super Audio CD]] (SACD), which was developed by [[Sony]] and [[Philips|Philips Electronics]], the same companies that created the standard CD.  DualDiscs and hybrid SACDs were competing solutions to the problem of providing higher-resolution audio on a disc that can still be played on conventional CD players.

DualDiscs took the approach of using a double-sided disc to provide the necessary backwards compatibility; hybrid SACDs are a one-sided solution that instead use two layers: a conventional CD layer and a high-resolution layer.

Hybrid SACDs claim a higher compatibility rate with conventional CD players than DualDisc, because hybrid SACDs conform to Red Book standards. However, a SACD or SACD-capable DVD player is required to take advantage of the enhanced SACD layer. With a DualDisc, consumers could use their existing DVD player to hear surround mixes. (DVD-Audio capable players are required for higher-resolution audio, if present.) In 2005, it was estimated that 75% of households in the United States have at least one DVD player.<ref>''[http://blogs.zdnet.com/ITFacts/?p=905 75% of US households have a DVD player] {{webarchive |url=https://web.archive.org/web/20060114084010/http://blogs.zdnet.com/ITFacts/?p=905 |date=January 14, 2006 }}'', ZDNet Research, April 6, 2005</ref>
