Shahinian Oblisk

I would like to thank all of you for your useful insight on this topic. It is because of people like you that makes this site a pleasure to visit. Happy New Years to all!!!

As a fellow Shahinian-McIntosh-owner, my experience is that the Obelisks sounds best with the 8-ohm-tap

Speaking of Obelisks...
While this doesn't have an exact bearring on the specific question, if you go over to audio asylum and do a search on these speakers, there's a discussion from a year or three ago re. the unique design approach Shahinian takes with them and his Diapasons.
If I understand correctly, the Obelisks purposely use the acoustics of the listener's room to enhance a life-like presentation of the music. Since the actuall room is therefor in a way part of the speaker, I wonder what the ideal listening space for them would be with that in mind.
