Quoting from the above:

 

"The question on the minds of current Nenuphar owners is obvious: should they step up to the V2?  Chances are steep. They've carefully cultivated then locked in their ideal balance with the right amplifier and DAC already. If owner acceptance of personal right lives inside a very narrow window, that balance will predictably tip. Now it'll need readdressing; again. That could mean more hardware expenses. I can't predict the appeal of that unless one was still laboring over this balance."

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.
