ZD,
Thanks for the suggestion!
Ive since purchased that unit and along with REW, smoothed out the null and peaks that my treatments weren't able to fix.
I have also EQ'd to a house curve to resemble a Fletcher-Munson curve and shelved the treble to tame the brightness of the 801N.
I am very satisfied with the flexibility of the unit and will be playing around with the stereo width function once I have finalized my house curve.
