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

Thanks david & abd for the quick and elaborate replies. I feel now comfortable ordering my 300B amp.

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.
