i tried Room EQ with just my laptop mic in test mode... i thought it worked great. Somebody else posted that the difference in the corrected sound is that it is not forward nor fatiguing at all... really nice with no annoying humps... uncorrected it is like the speakers are saying 'hey, notice me!'... I actually like it both ways depending on loudness.. but if wanna turn the dial to the right, Room EQ is very good and works as a Plugin with Audirvana.
