I think Rene wants to create a processing loop where he can have Dirac Live as room correction. I think he will run into handshake issues and lost capability. From what I gather he wants to use the HDMI output of the pre/pro out to a magic box which does Dirac Live/DSP and then back into the pre/pro for output to the amp/speakers. If I really wanted Dirac Live and didn't already own a processor I would go for the Emotiva XMC-1 which includes it standard. Personally, I prefer the old manual method just for simplicity or use Audyssey and then adjust as needed. The PEQ and REW option in the 976 and maybe the Phoenix is a heaven sent setup for those who really get into the tweaking of their systems. The system Rene describes is so one off I don't think he will get much input here.
