Man, you do beautiful work. As someone that's a big fan of the design, I'm really happy you seem to hear exactly the same qualities about them that make them so impressive to me!
Now, imagine that driver integration, sweet musicality, sheer resolution and overall excellence but scaled up to be able ti image very large, massive, room filling soundstage, with zero box sound and bass that crushes just about everything - that's the NX-Ottica!
Back on topic - you are incredibly nice to build the Monitors for your dad, I'm sure he's going to be extremely happy with them.
