@khragon  I replaced the rear rubber feet with edenSound regular brass hemispikes. These are NOT threaded (they have a flat surface). I used double sided adhesive discs.

I don't recommend using isoAcoustic GAIA for the front since it's important to maintain the angle (and height) that Cube's designers/builders chose. You can play with both the height and angle, should you choose to experiment, however results will vary.

I used Townshend Audio's Seismic Isolation Platforms specific to the Nenuphar's weight and size (footprint). I ended up removing them. Others, I believe, continue to use them. Mentioning this as your results may vary based on a number of factors.

If you search for Eden Sound and Townshend within this thread, you will find posts and discussion regarding isolation.
Thanks for the response guys.. couple reasons, mostly I got the Gaia with a deal so thought I give them a try, and my listening room is in the garage, with the floor slope downward already, at what I think is around half (or maybe a bit more) compared to the Cube design, so I think having the speakers level would be more inline with the original design.  I could always use a shorter spike, but thought I try the Gaia.  I order a set of the NSMT outriggers: https://www.nsmt-loudspeakers.com/content/speaker-outriggers.
We'll see how that go.. if not I can always resell them.


@khragon No harm in trying since you already have them.

My reason for not recommending the GAIA footers is because of the soft rubber base...which will bend and result in only a portion of the GAIA to be in contact with the floor due to the design of the Nenuphars. This will be exacerbated due to the tilt of speaker. GAIA footers are effective when they are evenly compressed and fully in contact with the floor surface.

AND their height, which introduces another variable.

BTW, I have GAIA footers.

Looking forward to hearing how it goes.
Hello Fellow Travellers,

It's been a very interesting 19 page read...thanks for all the information.

Now this may have been already raised and answered - if so, I do apologise.

I am wondering if anyone has direct comparison of Nenuphar/Mini against Rethm Saadhana or Voxativ Ampeggio

I had Saadhana V1 and loved them...and have extensive experience with Ampeggio. Could live with any of them.

But Nenuphars are compact.

Obviously Rethms go deeper as it has fully integrated subwoofer and both Voxativ and Rethms are more sensitive...not that it matters as I'll be driving them with Cymer 13e1 amps (28w - 8ohms taps only) and would love to know your thoughts....

I am more interested in holographic imaging, overall balance, and bass performance...(not overly interested in midrange or uber details)

Thanks in advance.

@pulinap All three are excellent options.

I believe Srajan Ebaen of 6Moons, given his exposure to all three brands (as well as the models), may be able to help. I recommend sending him an email through his site. There are options for the communication being Private or being ’Published.’

Given your previous exposure to Rethm and Voxativ, and understanding of both, a personal audition of the Nenuphar / Nenuphar Mini makes even more sense. 

Let us know what you find out and which one you decide to go with!
