@abd1  You have excellent company and are in a very good place with your Alan Eaton and Primaluna amps and those tube choices at your disposal. For me, reading your post is happiness inducing. Thanks!!!
david_ten I was curious about the platforms and since my last iteration was with the speakers on their spikes I've done a little experimenting.  I found that I much prefer the Stillpoints Ultra SS in place of the front spikes!  I'm not sure if I like them better than the platforms, but all this has made me realize that driver height makes a big difference with the Nens.  Off the platforms the middle of the driver, dare I say tweeter?, is pretty much at ear height.  On the platforms they are almost 3" higher.  That alone, regardless of what the platform technology is doing, is going to impact SQ.  
@stephendunn  Correct!!!  Placement is such a critical and rewarding factor with speakers in general.

Have you raised / have you considered raising your listening position to accommodate the 3 inch height increase with the Nenuphars on the Townshend platforms?

I imagine the results will be different with the bass reflex cabinet designs (i.e. sealed bottom cabinet versions) ???
david_ten  No I haven't tried raising my listening position--not really practical.  Trying to figure out now whether I like center of driver at ear level or not...
I’ve also found a modest but worthwhile improvement using Stillpoints in place of the factory spikes. Stillpoints makes some adaptors that work for the Nenuphars too. I think they’re for the Acoustic Zen Adagios, going from 1/4” to M6.
