@stephendunn Stephen, good and an important question. NO, regarding:

Do you think the not subtle improvements you heard were partly attributable to lowering driver to a plane closer or exactly ear height?

Suspended hardwood (oak). Seriously suspended as our homes in this part of Louisiana need to be a few feet above the ground. In other words, there is no basement below. There is no carpeting; I have a wool throw / area rug (5’/9’) between the speakers which extends to my seating position.

is your floor carpeted, wood or other?
@stephendunn  Did you experiment?

I’ve also have been thinking about your taking the Nenuphars off the Townshend Podiums and putting them back on the floor.

If you are interested in Nenuphars but you don't think you can afford them, there is an alternative approach, which I took: I purchased just the F10 Neo drivers and had the cabinets built in the US. More details in this thread:

Hi everyone, I've been following this thread closely for a while now.  So much interesting information. My curiosity about the Nenuphars has been though to control after reading all experiences here.  I want to spend some quality time listening and experimenting with them.  I've been a fan of dynamic speakers for a long time and keep hearing about efficient full range and their optimal matching with tubes wich I consider essential for my taste also. My last speakers have been Dynaudio and for most of the time it's been a great experience and a joy to live with. They have been doing all the good things for the longest time now but the Cubes just keeps popping up in my dreams.  My system is pretty basic and straightforward, it  consists of a HD plex fanless computer withthe goodies, a lampizator big 7 dac and a LTA 40i integrated amp. Although the system isn't totaly focused on the powerful side it can handle a good size speaker no problem but I can only imagine going the eficient and simple path root.  Though decisions.  .
@ricardoosusa Please do report back if you take the plunge.  I'd love to read about the experience of comparing Dynaudio and Cube Audio.  Such different approaches, it would be very informative.
