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

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. 

khragon Meant to ask what pre you have in front of the SIT-2?

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

Khragon, did you ever compare Apherion with the Townshend? Thanks.

I am using a full PS Audio stack:

P15 Power Regen
DSD DAC Sr
BHK Pre

I used to have BHK250 amp buy sold that in favor of the SIT2.

Sorry I didn't compare the Aperion to any other brand.  I did compare their TOTL model the dual AMT to the lower aluminum ribbon model.  I think I could live with the aluminum ribbon model, they were very close.  With exception of the sensitivity so for maximum compatibility later on I went with the AMT, that and I thought it's a bit more airy.. but that could be the price bias taking.
