The New Nola Boxer 2 upgraded to a 2S

I'll be without any speakers soon so I'm considering a pair of the new Nola Boxer 2. I see that there is also an upgraded version called the Boxer S2. Nolas S2 literature says: "High speed Mundorf oil capacitors along with Nordost silver mono- filament wiring are employed to compliment the new bass drivers. Improvements in transparency, dynamics, bass definition and reduction in "hash" are very audible." This option adds $1000 to the base price of  $1700. 

My question:
Has anyone listened to this upgraded version?
How about the base version of the New Boxer 2; have any of you heard it in comparison to the original Boxers? Impressions? 

I'd be willing to spend the upgrade money if it was truly an audible upgrade. I know the sound of the original Boxer and loved it, but there's no such thing as a Nola dealer in the Detroit area so I have to rely on word of mouth, reviews and ultimately buying a pair to decide for myself.

The thing is, when the price jumps to $2700 it begs comparison with other great choices around $3000 like the new Elac Adante AS-61GB or the  ATC - SCM11 v2. I'm not locked on anything at this point but whatever I decide on will sit on Sound Anchor Signature, 3 Post stands (24").
