Dirac Live - horrible? Dont work

This is an old app for NAD T or M series AVRs and, as you saw, the ratings are low and there are warnings that it doesn’t work. Why are you surprised?

Doesn't seem that it is working properly.  In my experience with DL, the resulting corrections should be readily seen in the curves and the resulting sound should be lower in gain as necessary for overhead compensation.  

I've not used that particular version which is proprietary to certain NAD AVRs.  There is an active Dirac discussion/thread on AVS which you might find informative.

Yes, but what does one see in the curves? 

1.  The difference in FR between the measured and the predicted result as well as the correction FR, itself.  You can confirm these with REW, if necessary.

2.  The difference between the original impulse response and the predicted result.
