My concern is that too many audiophiles that I've met consider room/speaker eq as the ultimate panacea. IMO, it is not.
Finding the place in the room where seating yields the smoothest bass is paramount. DSP cannot correct nulls. Trying to do so only causes more severe issues.
Finding the optimal position for the speakers, once you know where to sit, is critical. These adjustments can be exceedingly slight. When you get it right, it's another ball-game - I call it
Playing the Room, but it really is working with the room to the best extent, rather than against it.
Finding these locations can result in an uncanny sense of presence, tone, & dynamics, as if the performers packed up their gear to come to your house (unless the recorded perspective is more distant, in which case you are transported to the venue).
DSP might be of some assistance where all of the important organic steps have been taken, but certainly not before.
But I've NEVER heard any DSP system find that
right place in the room. It seems that it cannot measure or even recognize it.
Best,
