Cube Audio Nenuphar Single Driver Speaker (10 inch) TQWT Enclosure

I've really enjoyed this very informative and civil thread.  I have a First Watt SIT 3.  I also happen to have a Decware Zen Triode SE84UFO2 on order from this past February, so I will have two amps which pair well with these speakers.  Currently the SIT 3 powers a pair of Zu Audio Soul Mark IIs.  I'm considering the Nenuphars, but am curious if they are geared to certain styles of music, or if they play well with all genres.  Thoughts?

Thanks for the responses.  Honestly, my biggest concern is they cost 15k, so I don't want to find out later they're amazing only with acoustic jazz or something, and everything else is just fine.

The music I've been listening to lately has run the gamut from old A Tribe Called Quest (hiphop), the new Billie Eilish album, Faye Webster (indie singer songwriter), Kelly Lee Owens (electronic) Darkside (um?) And Badbadnotgood (jazz). 

I've been pretty satisfied with my Zus, especially when I moved from a PrimaLuna ProLogue 5 to the SIT 3.  (I have an LTA MicroZOTL preamp, and also run a pair of Rel T5i's.)  I'd say this combo brings a lot of that "alive"-ness factor to the table, but it sounds like the Nenuphars take things to a special level, and I want that.  

@david_ten.  Thanks for that specific feedback.  I like that you play stuff that's hits harder than my examples.  I think that's the right word for the sort of music I wanted to make sure the Nenuphars could handle.  Thank you for confirming!
