In my case, "correcting for the room" is curious:
* I just made significant changes to the room with acoustic panels (I suppose it used to be even worse?)
* In this system, I am listening to small monitors in a "nearfield" configuration
Is it possible that my EQ curve is adjusting the curve of my speakers more than the curve of my room?
In any case, it really is a surprisingly big difference.
Mark Levinson could put the chip in a big heavy case with red LEDs and sell it for $30,000.
