upgrade from Devore Nines


I am driving a pair of Devore Nines, with LFd integrated amp (50w), resolution audio cantata cd/dac in a 15×18 dedicated room.

I am contemplating the super nines.  Anyone completed this speaker upgrade?  I like Devore speakers (at least what I heard).

Any other upgrades from the Nines others have taken and been happy with?

I'm very familiar with the sound of the 0/93 (and 0/96) and they of course have that Big, Thick, Rich sound.  Do the Super Nines sound "thin" in comparison, or do they maintain a good sense of body to the sound as well?

The Super Nines (S9's) are a definite upgrade over the 0/93's, which are an upgrade over the Nines. I have owned all of them. The S9's are a big improvement over the 0/93's in every category...better extension, imaging, etc., yet still possess that Devore tone and tactile quality.  Anyone contemplating the purchase of the 0/93's should save up a few more bucks and go for the S9's. And they will be huge upgrade over the Nines.
I forgot to add, that I do not find them to sound "thin" at all. They are also quite a bit more dynamic sounding!
Thanks again grk.
It's a real shame I can't hear the super nines before I purchase the Joseph speakers (which I love anyway).  I told my local Devore dealer to let me know if he ever gets a pair of Super 9s in to audition.   I auditioned the0/93 and 0/96 and ultimately liked the 0/96 better, but their width (and cost) create some issues in my room.  A slim version having similar attributes, like the super 9, could be just the ticket.  However, they are way too expensive to just buy without hearing them (in my case).
Out of curiosity, how close do you listen to them?  I found the O series to require at least 8 foot distance in order to sound their best - to sound coherent, focused, with "snap" and "air" (too close and they start to sound a bit unfocused and glazed over).   I know Devore recommends at least an 8 foot listener distance for the 0 series, presumably for this reason, and I've wondered if this is a consequence of the particular design of the O series, or if there is something about how John D designs al his speakers (e.g. crossovers/drivers etc), which necessitates that distance for them to cohere. 
They are a bit over 12' from my listening position... about the same distance (more or less) that the other speakers were placed.
