sim_audio_nerd, 
It's possible that you may prefer the Bakoon to a SET but you'll never know without comparing.  What you've found in the SS to tube preamplifier transition (Air,space,liquidity) pretty much can be the case for tube amplifiers as well.  

If you do decide to venture into SET or some lower power push-pull tube amplifiers,  make sure that they have good quality output transformers and power supply. Both factors are critical to achieving very good sound quality with tube amplifiers. The Nenuphars will sing!

Would love to try a Bakoon for my Nenuphars but cant find any dealers selling for much less than MSRP.  Every other brand Im interested in I can get at least 20% off. Its a pity

Choices are plentiful. You’re very enamored with the Voxativ and it has garnered much respect and praise. I could see you being happy with them and understandably so.
~~~~~~~~~~~~~~~~
Intuitively I know the Vox will perform as expected = what I've always been searching for.
Some  of the Vox speakers have low sensitivity, 91db, which may not be so bad, provided the midrange is high fidelity, with no stress, no distortion. 
Their new model AC1A is rated 97db, I have the power to run the 91db Vox, but why not go for the super sensitivity at 97 for the same price??
btw the Cube is rated 92db, thats below my standard.

I've heard several systems not made by Voxativ that utilize their drivers and the drivers certainly prove to be quite good.  They do a good job with fieldcoil magnets.  G.I.P. Laboratories, a Japanese company also makes a very good fieldcoil wide range driver that is around 12" in diameter.  The downside is the price which is way up there in Feastrix territory (they make a decent fieldcoil full range driver too.  

Among the best sounding full/wide range drivers currently available are the models made by the German company AER.  The prices range from expensive to crazy expensive, but, I've heard systems employing their drivers that sounded remarkably smooth and lacking in harsh peaks that are common to this type of driver.  

It is a bit of a sad state of affairs that some really old, no longer made wide-range drivers remain among the very best ever made.  I would take the Jensen M-10/ERPI 4151 13" field coil driver over almost any other such driver out there; add a good tweeter you can have an almost matchless system.

~~~~~~~~~~~~~~~~
just cked out the AER web site,
The speaker looks good.
Will stay focused on Voxativ AC-1A.

EDIT
WOw that was fast, back froma  snippet of a YT vid on the AER.
huumm
might have to rethink this ,,,i mean, not sure if a  decision can be made overa  YT vid, but based on this clip, its unreal.
Not sure what AER driver is in this cabinet.
Going to discuss this with Richard Gray, see if he has any ideas which direction I shpuld go. 
Most likely buy one lab(Vox) late sept, then the other labs late next year  have  a  shootout and sell one pair.
