The target curve was deliberate. It just sounds nice to me.
I'm using a 2x4 unbalanced MiniDSP. It's running the 2.1 plugin and handling the hand-off between the 1.7's and Rythmik. I've been pretty pleased with how it works. I may look into the new Dirac unit they're releasing to get these results on the rest of my channels. My only gripe with the 2x4 is the .9V limit on the output.
