Cube Audio Nenuphar Single Driver Speaker (10 inch) TQWT Enclosure

@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?

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.  

At 92 db/w efficiency, whether or not something like a single-ended 300b or other small triode will work depends a lot on how loud you like to play the system.  With most single driver systems, you have the BIG advantage of the speakers sounding really good--lively and engaging--at quite low volume.  I liked the Nenuphar playing at low volume.  I liked it less when the volume was cranked up.  That is not a big deal to me, because I like low-volume listening, but, it is something to consider when looking at this kind of speaker and the right amp to work with the speaker.
