Ok...I'll help.
A DAC is a digital to analog converter. Your NAD has one inside. Basically, every cd player is really a transport (the part that spins the disc), a DAC, and a power supply for both. Pure Trasport? yes, there are just transports that won't do much for you with out a DAC. Most DAC's (and transports for that matter) will not work with SACD. It takes a special interface (computer type connection).
Will a DAC help you? Hard to say, depends on the DAC. With you NAD setup, you might just try a better CD player, if you can hear the difference, then maybe go that route. Opinions may vary on this, but unless you are going to spend several k on a DAC, I think the one box players are likely the way to go...
Now you might really like a SACD player...or try a turntable (I just had to get that in somewhere!)
