I realize you know this...listening via an outboard DAC/Headphone Amp and Headphones highlights remarkable differences in the presentations.

Stumbled on this mini-review of the Nenuphar and I don’t believe it has been posted here yet. I find it to be the best description of their sound character I have seen:

Thanks for providing that link.  As a non Nenuphar owner I confess that I have much admiration and respect for this speaker. It seems to nail all of the criteria and parameters that I find most important, even mandatory. I remain exceedingly happy with my Coincident Total Eclipse II speakers (13 years 😊).

The Nenuphars are 1st on my list if I ever decide to change speakers. I do believe that they represent an extraordinary achievement. I completely understand your happiness and satisfaction with them. I believe they’d be a superb match with my Coincident 300b SET mono blocks with their low damping factor and zero NFB design/circuit.
