Seems to me if current Nenuphar owners have their system dialed in to their liking, I’d leave well enough alone. Or as Ebaen suggested you’re just changing components/cables again in an attempt to match the voicing of the new driver.

 

If one feels they will benefit from the fuller voiced new driver then go for it.I believe the original driver is a remarkable achievement.

Perhaps the most important quality of the Nenuphar's--for me--is their ability, with the right amp, etc., to create a bewitching or what SE described as a psychotropic sense of presence.  In describing the sound of the upgraded driver, SE claims it has "a bit less presence-region amplitude, more weight."  This is a big red flag for me, especially since I've achieved "more weight" from the addition of a sub.  Losing this upper mid-range-presence-magic might be impossible to regain with component or cable swapping.

Just conjecture on my part, since I haven’t heard the new driver, but I have been following six moons for quite some time and heard some of the same equipment so I feel I have a general frame of reference, I welcome the change or perhaps addition -maybe they should make both drivers available. Srajan doesn’t seem to suggest that the new driver is better, just different. However, I think it’s great there might be a single driver speaker with a warmer tonal balance. Not everyone wants to dance on the knifes edge but still enjoys the things that single driver speakers do well such as easy to drive, no driver discontinuities, great imaging, etc. Just my two cents.

Good observations. It seems pretty clear to me that Srajan was making the case that the new driver is "different " rather than better. It would be really nice if both speaker drivers were to be available. I believe that the new driver loses 2 db of sensitivity.

new driver is "different " rather than better. ~~~~~~~~~~~~~~~~~~~ Yes correct I just cked the web site, Cube mentions **Our Mark 2 cone is now in our speakers..** But Cube does not specify exactly what is so dif in cone material. Cube fails to mention exactly what the original cone material is made of, nor what is so dif in the new cone composition. The pics look identical. I see nothing new in the photos. \ = Cones look identical. Someone please tell me whats going on? I think we all deserve to know. The prices seem to be the same. Cube needs to come out with a video explaining exactly what is the dif between old cone vs new cone. And in terms of bass, mids highs between the 2 cones. I think Cube handled this new upgrade with a stand-off-ish-ness. A bit too rushed , or lets say, lack on planed implimentation..in the intro of the new **break-through*.
