Hi bebruatigan,

You experienced a very dramatic form of the 'break-in' process. I am glad you had the patience to give the Nenuphars a chance. Some listeners would have  come to a premature conclusion and given up on them. I have no doubt that your are hearing superb sound with your new system. Congratulations and enjoy this for many years.

The preamp is the Linear Tube Audio MZ3. I use the speaker taps to the Zu Undertone. The dac is a Border Patrol SEi (I leave the tube buffer off). An Antipodes EX running Roon and Qobuz is the source. 
Over on AudioShark I came across an interesting post about Nenuphars and the Gryphon Diablo 300:

Yesterday my friend brought all his system to my home. He wanted to know why i m so happy with my new speakers, Cube Audio Nenuphars.
Full range, single driver, no crossover 6 ohm and 92db.

His system consists of: 
Gryphon300+dave+mscaller+n10.
PC from True Signal, SC Sablon t.o.r, IC Atlas Mavros
PC for gryphon: Sablon t.o.r.

I drive my speaker with mbl c51, 300w class D.

Guess what? Gryphon is an amazing match to these moderately sensible speakers! My friend was speechless, anticipating a bad match! I guess Gryphon, when used at low volume, throws class A only power, and that's what these babies like the most.
Diablo 300 is a Darkish sounding amp....I guess as long as you like that kind of presentation. Have ordered a pair of the Mini Nenuphar's but they wont arrive till the Fall. Completely sold out of everything except 1 pair of the Magnus is available from the distributor according to my dealer
