Feri, just for you, I will do such graphs, and just for you shall post them. Averaged FR with the standard audyssey config and averaged FR with the clustered FR. I will overlay the MLP graphs for both and then a chosen few seats averaged outside the sweet spot. Sound good to you?
Sounds to me like you just have very capable subs...The gains at the levels they are will not limit you. seems to me like you hare happy and all good so no worries
If both have xt32, then both would have dynamic EQ and subeqHT AFAIK. I haven't run across a unit that offers one and not the other except for the av1hd upgrade which was a slimmed down version of xt32. I could be wrong tho
