I have one between pre-amp and power amps, analog-in to analog-out. It greatly improved the low end by removing big peaks. Main speakers now can play bass with no need for subs, booming is gone.
Most room problems are under 150HZ so this can make a big difference and I am not even using the other features, parametric eq, etc. Just set and forget. You do have to be OK with everything having an A/D/A conversion but, to my ears, it is transparent and its output drives my mono amps fine.
