Shahinian Obelisk vs VandersteenTreo


HI fellow ’goners.
I own the Shahinians, thinking of upgrading to the Treos. The Obelisks sound a little smallish for the room... And the room is not square, it's a big living area of a house, with access to the second floor's roof. 
Will this be an upgrade or just a sideward move?
Room approx 60m2, driven by Musical Fidelity A5.5, 250wpc at 8Ohm (thinking of replacing this one too).
Mostly jazz and acoustic music, less frequently - classical and pop.
Thanks!

Sorry, I did not clarify. Treos are good speakers. No problem with their extension; I find the LF is just not articulate. The quatros are better. I have heard the sub combo. It is not for me, so no argument there. The later quatros solve the midrange dip problem. Don’t have to believe me, stereophile measured it, although I think the reviewer underplayed the degree. I have a pair of B&Ws with very similar problem.

I think some of your disappointment might be with the Shahinian's. 
Another might be the preamp section of the integrated amp.
Though without being there, it is hard to give a good reason.
Unless, you want to fly me to Russia...;)

hope you have a fantastic vacation here
i did a bit of an AM email exchange with RV
the measured response was a room floor bounce / wall coupling issue that JA did measure but that you do not see in the anechoic chamber plots, completely fixining it for real rooms = box like sound that Vandersteen not known for.
the Quattro is designed for closer placement to back wall for ( my words) WAF
you might chat with RV about changes thru the production run prior to the CT
i did not ask about that
i am a fan with 7 MK2 in my home and his amps on the way so I am bissed
2nd home will get Quattro CT
some day

Tomic601,
Thanks, enjoying VA right now. Next stop Boston, then on to Niagara and on to Chicago :-)
You were saying "his amps". What exactly did you mean?
