Thanks flak. I would still prefer an external unit to replace the parametric eq I currently have. Like the OP, my issues are with reflection points, not being able to use acoustical treatments, and less than ideal speaker placement.
I wish Dirac would make an external unit since I have multiple sources (i.e. Oppo, turn table, etc.) and that it worked with Windows XP. Hint, hint! Wink, wink!
