@keithr Hopefully someone who's actually done the comparison will step in, but I suspect these two designs will sound very different. You can likely catch some of that if the read the two corresponding 6moons reviews and compare some if the descriptors used across across them...

E.g.:
See paragraph 3 here - http://www.6moons.com/audioreviews2/zu3/6.html
And whole page, but especially final paragraph here - https://www.6moons.com/audioreviews2/cubeaudio2/5.html


Cal,
That referral to 6 Moons is a good idea. Srajan Ebaen has been an admirer and user of Zu speakers for quite some time. He has reviewed a number of their models very favorably thorough the years.


He was very taken and struck by the Cube Audio Nenuphar and seems to place them in their own singular uppermost tier category for single driver speakers . He is astonished by their sound quality and presentation.  Although Zu utilizes full range drivers I realize that it isn’t a single driver speaker as is the Nenuphar.

Charles, interesting indeed. That said, Srajan likes a music genre that really i'm not into (world acoustic) and his writing is often confusing. 

I will say I heard the Voxativ 9.87 in a dealer's home and wasn't impressed as his (and others) reviews. That said, I don't believe it was broken in near enough. It had wonderful jump factor, but also clear as day, uneven frequency response issues in various parts of the spectrum. The bass was also dry.

I've been toying with the idea of getting a second speaker (YG is my first) and Zu/Cube are high on that list. The Druid VI is considerably less expensive, but seems to be more of a rock n roll speaker vs a classical one. I can say previously owning Definitions that the old Zu's strengths weren't on classical. The Druid VI bridges the gap much further but still doesn't seem like that speaker's favorite genre.
 
FYI, since Ag / Argentum, aka Silver is on the menu...

The SR speaker cables I used are high purity silver 99.999%

The Scott Sheaffer speaker cable I am using is also high purity silver, though I do not know the specific purity level. Knowing Scott, his sourcing and selection is impeccable.

As mentioned above, though Scott's cables edged out the SRs and I clearly prefer them in my system, the SR cables are superb.

Good to read the back and forth above. As @debjit_g mentioned, the thread had been dormant for a bit.
Keith,
I’ve heard Vaxativ single driver speakers a few years back and I wasn’t blown away for certain. Thin in the midrange and bass shy. From all indications the Cube Audio Nenuphar is a much more complete and satisfying speaker. I have no reason to doubt this as a fair number of listeners have confirmed this assessment. It's reported to be quite adept with all genres of music.
