The DA2 Digital Audio Module is McIntosh's newest and most advanced module for processing digital audio. It comes standard in the C53 and C2700 Preamplifiers, allowing both of those units to take advantage of some of the latest innovations in digital audio technology. McIntosh products equipped with the DA1 can now be upgraded to the newer DA2.
The models that can be upgraded are: MA9000, MA8900, MA7200, MA5300, MAC7200, and C49. (Note: These models will continue to come with the DA1 installed. Upgrading to the DA2 is optional and must be installed by an Authorized McIntosh Dealer or Authorized McIntosh Service Agency.)
