My 2 cents:
There is no substitute for room treatment, make the room as good as you possibly can.
I have trapped my room like crazy and it's pretty flat except for a 6dB peak at 47Hz.
There's just no way I can fit in more trapping so I was very happy when the room correction DSP (autocal) in my Genelec 8240's took care of that one for me.
That said, after getting the Genelec 8240/GLM kit system I believe that good room correction dsp CAN improve on an already well treated room but only do so much in an untreated space.
Ethan, you should get the Genelecs demoed. It's quite impressive, you might like it.
