Dirac - worth activating?


Have pretty much ignored using Dirac from a NAD processor.  Worth doing?   Is it of value/impact sound from preamp used for stereo?

Does anybody have an idea how DDRC-24/ Dirac handles analog input. Does it get reconfigured into a digital signal and then convert back to analog by a DAC in the DDRC? 

If that's the case, is the sound quality degraded by being processed a second time because my streamer has a built in DAC and I go directly from the streamer to my amp. There is no way to integrate the DDRC between steamer and DAC?

And just what the heck does dirac do to the signal?  Anybody know what dirac does under the hood?????

Their website talks about the Dirac delta function, and transfer functions to undue the colouration of the system.

I am pretty sure it is similar to the modem channel correction that fred harris (of Blackman-Harris fame) did many years ago.
