This is basically how I see..hear things. I mean whats the rush? If it sounds great as **IS*, its too risky going for *2 birds in the bush**

. Seems Cube has the magnet down pack, maybe they feel there was a mod to be done on the cone. As you guys know in FR speaker tech. magnet quality and cone material, Both equally of highest importance. Voxativ has 1 or 2 wooden models, and the rest is this super thin paper garbage. AER has their own in house paper traeted which they will not even whisper 1 word the composition, = *Top Secret** Tang band has a really nice banana fiber which I like , but not up to the wood level in some lower fq;’s. Fostex has smashed Kenaf leaf fiber. And alsoa double sandwiched cone model. So every manufacturer has taken their own specific route in cone material. I’ve looked at Cube’s site, they really dont go into the composition. Seems like paper composite, nice and stiff. Cube w/o doubt has the finest magnet motor with 81 Nd cylinders @ 1480 grams of pure Nd power. That aint cheap ya know.

But then the sens level is a bit too high for my needs/preferences. Small room, near field, low SPL. 95db sensitivity is ideal, or actually I;’d prefer 94 db, sens, but I ain’t complaining.

The DLVX6 is a wonderful 93db sens, which just BARELY allows for me to work it in with the VX8. Had the VX6 been 94db, sens, it would be 1 db sens too high to employ as a backup dual. basically it all comes down to which manufacturer has the cone material that sounds best to you and your music selections.

 

Keep us informed how the new cone upgrade sounds vs the original cone.

Srajan Ebaen has wrapped up his ’review' of the Nenuphars with the F10 Neo V2 drivers.

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."

- Srajan Ebaen / 6Moons

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.
