khragon Thanks for posting about your use of the Apherion supertweeter. I’m curious about how you have them installed. If they sit on top of the speaker, the rake would make them point far over the listener’s head at the front. My understanding is supertweeters are highly directional. Or do you have them propped so they fire straight ahead? Maybe the Apherion drivers provide more dispersion. Insights into installation would be appreciated.
Here are some photos of the setup:https://goo.gl/photos/rinLZWzHoBvCizNLA
I have the supertweeter on the same plane as the speaker, both slightly toed in into the listening position.
khragon Impressive set up!  Thanks for sending photos.  Rare to see the Nens with the grills.  Don't think mine even came with.  More importantly I see how you've installed the Apherions (and subs) and I'm thinking I will try the supertweeters given they have an in-home audition period.  I have had speakers in the past that benefited from forward only firing super tweeters, but think the dual design is the way to go, adding depth and probably air to soundstage.  I am in a relatively small room and although width of ss does not seemed cramped, depth does. With the SIT-2s in place, along with the help at either end of the spectrum, I bet your Nens sing. 
Would an 300B amplifier with the following specs be suitable for the Nenuphars?

10W per channel
Damping Factor 10 at 8Ω load at 1kHz
-6dB of negative feedback
