We can supply Nenuphar drive units World wide and are looking into cabinet designs customers can use. We can also supply Townsend Podiums to use with the Nenuphar’s.

@rixthetrick YES! Grandinote's Massimiliano Magri’s Magnetosolid Tech based electronics and his speakers are really, really good.

I have about 100 hours now on my Nenuphars and just recently noticed another notch of improvement in the high register.

At what point did you feel the speakers were fully broken in?

Stephen, copied below [from 10-09-2019 / Page 2 of this thread] are my thoughts on break in for the Nenuphars.

Both Richard ( @toetapaudio ) and Jon Ver Halen may, based on their personal exposure and client feedback, find differently.

Here is a response I sent to @toetapaudio on my personal experience with break in:

"....Cube, if memory serves me, felt a few hours of runtime would be sufficient.

Jon Ver Halen, the US importer, put it at 40 hours or so.

Based on my experience, I peg it at about 150 hours before the Nenuphar start coming into their own. They definitely started sounding better after Jon’s recommendation of 40+ hours. So take 40 as a minimum, minimum...with 150 as my personally recommended minimum.

For ’full’ break-in around 500 hours for musical beauty, wonder and engagement.

An industry person I respect and who has significant experience tuning analog gear, felt 1000 hours would be needed. I realize ’hours’ of burn-in are a hot topic with folks falling on either side of the divide. I took his feedback and pushed for that 1K mark, after which I consider break in to be complete. However, If I were advising, I’d stick to the 500 hours with folks generally being happy with the results post 200 hours."

Thanks, David, I missed your post in the thread.  Hard to imagine there is more to come from these wonderful speakers as I  reach the 100 hour mark.

If anyone has heard of or experienced the Nenuphars being driven by 300bs, please let me know.  Curious about that tube's synergy.
