I had problems with the Dirac implementation on the AV 10 when I tried to set it up. Even Matt Poes was here and we couldn't get it dialed in right. I will have to revisit this AFTER I sort out the Dirac ART issues in my theater room. As Khan said to Kirk in STWOK "Time is a luxury I don't have".
In my experience, limited by the PC standalone version, there is one issue with DLBC, in that a) it won't dial in the crossover for the best looking graph so one has to changed them slightly and see if, for example, the auto selected point, say 70 Hz is not as good as 75 Hz, b) if you make changes to the target curve, you have to click the desktop screen at the right place and click "calculate", the sequence of the "clicks" has to be right, if not, your REW graphs will not show the best results. It is hard to described the process, one must use REW to check the results after each target curve customizing to ensure nothing get messed up (not really mess up a lot, but just that you will not get the best looking curves). Other than that, it works much better than ARC Genesis's bass control, that is what they called auto phase/optimization etc.., I have plenty of REW graphs to show.
So, if you like what you are getting with Mult EQ X, Dirac Live, while better/more effective in smoothing the bass without customizing, it does require one to know exactly what to do after customizing, but if you do it right, you will likely get better results that what you can with Mult EQ X, all else being equal, and either one, imo, is much better than ARC Genesis in its current form. That's all for pretty REW graphs, if one goes by ears, I would think all bets are off lol...
I really would love to review DLBC on an AVR such as the AVR-X3800H, and demo how to get great results (graphs), but I have have the Anthem, and an AVR-X1800H so I would get into big trouble if I bring home a X3800H. So, I can wait to see you and Matthew get back into reviews on those, though I understand as much as you guys want to do those in depth reviews, you do have to make a living (or fortune lol...). Too bad I am far away in Canada, otherwise, as a retired EE with lots of free time, I would do it for you guys for free/and fun.
