I have one of these in my 2 channel system https://www.minidsp.com/dirac-series/ddrc-22a, a friend brought round his laptop from his PC based system with the Dirac software loaded,we ran the set up for my system and the differences weren't subtle,very pleased with the results,clearing up the bottom end allows so much more detail to come through as well as increased width and depth of the soundstage.

Have now heard Dirac in 3 systems I am familiar with before and after,it's improved them by quite some margin,not cheap but if you don't have room for traps etc,or your married,or you have flea powered amps,the software reduces the volume by 10db,then go for it just IMO of course.
