@paullb Mentioning the following in case it is of interest:
Since Srajan Ebaen’s ’review’ makes note of these differences between the two versions of the drivers as implemented in the Nenuphar speaker cabinet...
If I move my listening position back by ~ 6 feet; which results in my standard-position toe-in coming to a point ~ 2 feet in front of me:
the effect (using SB’s terms) is a downward shift in weight, increased "blackness" and a reduction in the "incisiveness in the presence region"...the penalty: is a decrease in sound stage width...
[NOTE: a small couch (my preferred listening position) is likely a contributor as it is now in front of me; this outcome may be simply specific to my room, etc. etc.]
