Hi Guys,
Apogeelov, would definately remember you if I ever sell my beloved M3.
Halil - In ansa to your question, I did notice a significant improvement over the ARC's - mainly in the scale of the soundstage (presumably because the Arc's fire forward and up while the Obelisk's fire to all points of the compass from its pyramid top).
The Obelisks are trickier to place than the Arc's which are wonderfully easy to place and live with.
The Obelsisks like a lot of room around them 2-3 feet ideally from sides and back walls, but are very definately worth it.
Strangely the Arcs although being lower in the range, have a higher power handling capability than the Obelsisks and this is something you may need to bear in mind. I'm VERY careful with my 250 watt Nu-Vista amp for this reason and any owners of 200 watt plus Amps needs to bear this in mind to avoid damage to the speakers.
Regardless, these are wonderful speakers and like all Shahinian's offer insane value for money. For tech specs on the speakers visit the Shahinan site at: http://www.shahinianacoustics.com/
Hope this helps sorry for the late reply!
