I have a Tact 2.0 digital processor and confirm that it does a magical job of cleaning up the bass response in a room. When I swith the unit to "bypass" the bottom end becomes unbearably boomy. It's hard to believe that in pre-Tact days I tolerated this sound. Another less expensive alternative would be to find a Legacy Steradian processor. It is a very specific kind of analog equalizer, being an analog bass notch made specifically to tame room boom. One is able to adjust the depth of the notch, I believe. And as far as using power cords to equalize a system... I won't argue with those who have had success, but it's rather Rube-Golberg-esque way to equalize a system, don'cha think? Why not address it using tools intended for the job (i.e., digital or analog equalizer)?
