All AVR/EQ processors have their limitations. Hey Dirac live has its limitations. So you have to give them a head start by setting up speakers, subs listening position/s as a solid starting point, the results will pay dividends.
To give you a example, rare but does happen, my speakers cost a fare bit and always thought it never sounded that great on HT, its set up more for 2 channel, so never really worried about too much. But hey I paid all that money. The AVR (which cost alot and was the flagship model) didn't pickup on it. The expensive center (weighs 16kg) was internally wired incorrectly, out of phase. Picked this up via REW. People tend to think they can let the AVR do everything, and they do a reasonable job but never perfect. Some are better than others. As much as technology has grown it is still far from perfect.
Acousticans, professional installers use REW. Manufacturers of acoustic paneling use REW.
At the end of the day it is up to you, you like the sound then sit back and enjoy.
