I wouldnt recommend Tektron Amps as the Top of the Amps PIT and Tarnish after a short while.  They are changing this summer to what appears to be something like a Chrome top. Have no idea if those will Patina with age as well. I'd avoid em if you care about long term cosmetics or being able to resell them down the road.

Has anyone replace the rear rubber feet with something else?  How do you handle the mount?  I wanted to try isoacoustic Gaia but can only replace the front spikes since they are threaded and the rear ones are just wood screw.

Why not try a Townshend Platform instead of Gaia or similar products. Suppose to be better for optimal performance.

@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.
