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

I can see no logical reason why a high quality 300b SET would not be an excellent choice to drive the Nenuphars. @ mga71 congratulations! Are you acquiring a name brand manufacturer or is this a custom built for you amplifier?

I'm pretty much set on Audio Note UK. 

@mga71, 
Can't go wrong with that choice, should be beautiful sound quality with the Nenuphars.

As an update, I just posted this in speaker related another thread;

"I put one of these Zen amps on my Cube Audio Nenuphars and it sounds unearthly good. Using a Vinnie Rossi L2iSE with Elrog 300B’s for DAC and preamp duties. With these speakers the Zen sound amazingly natural and open - wide soundstage, wonderful clarity and tonality with great separation of instruments and voices. Bass is strong and deep. Within it’s power parameters I prefer the Zen sound to that of the Rossi’s own built-in Mosfet output stage (@100w/ch). All in all a surprising outcome - I’m sure the crossoverless Nenuphar FRD has a lot to do with the end result."

I think the one thing that most keeps impressing regarding the Zen/Nen combo is the "presence". Everything just sounds so vivid and alive. I should add that my Zen has CuTF V-Caps.

Already lusting for the Zen 25th Anniversary but the backlog at Decware is just too long for the impatient.

I see there’s a few reports of dealers getting in their Enleum’s in stock. Would love to compare the 23R vis-a-vis the Zen.

Also, just bought a Shunyata Omega USB cable to step up the information perspective from the K30.

Enleum is already out. My buddy has his hooked up to the Fleetwood Deville's and is loving it.
