David,
Thanks for the link posting. Srajan Ebaen really loves the Elrog 300b and as a former owner I understand why. It’s interesting that an upstart 2A3 impressed Srajan to such a degree. This Lanlai 2A3 is roughly 1/3 The price of the esteemed Elrog..

David_ten. Thanks for posting that link.  I will keep you posted if I decide to try the Lanlai 2A3–which I probably will. 
I’ve also have been thinking about your taking the Nenuphars off the Townshend Podiums and putting them back on the floor. Do you think the not subtle improvements you heard were partly attributable to lowering driver to a plane closer or exactly ear height?  And—pardon if you’ve mentioned this before—is your floor carpeted, wood or other?

Also appreciate your gentle shepherding to keep this thread on track and still informative to its followers. 
@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?

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:
