If you do give it a go, then let us know the outcome.
I used to have the Zsystem EQ, but with the emm gear you can't take advantage due to the optical connectors. You have to be so careful incorporating such units as it gets confusing(you like the new sound instantly and then query it after a few days or on different music) and then that gets dangerous.
I have always noticed that changing cables tends to take out some of the anomalies that may occur in the room. Hence that is why I dropped mating the sub or using the EQ as it destroyed the cleanness of the meitner gear and moved my spkr placement to compensate.
