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!

Vandersteen ships their speakers standing upright in the box secured to a pallet. The problem is, when a speaker is shipped this way and I suspect most speaker companies ship this way, it will put a driver in the speaker at risk of having its voice coil damaged when speaker is bounced or impacted. When I transport speakers in their box, I lay speakers on their backs so the voice coil will react more naturally  to a bounce  or impact meaning the cone will move up and down more naturally in the magnetic gap. This isn't perfect, but it does help in transit. I had to replace a cone midrange driver that was damaged this way. I did it myself, but I don't think the speaker manufacturer was as fussy about matching the drivers to the crossover as Vandersteen is. If Vandersteen could send you a properly matched driver, you could easily make the repair yourself.
Gentlemen,
They were hand-delivered to me by the seller's nephew in his Land Rover (he was going somewhere further).  Although they wrapped them up well in bubbly cellophane (whatever the name of this material is), I guess it took some damage.  Or maybe it was defective upon dispatch, I don't know.
I got in touch with RV, he is willing to rebuild the driver, since he has none of them left in stock. A very helpful gentleman indeed. But this requires taking it out and sending it in, which takes a lot of time, especially around Christmas. 
Gentlemen, on the sidenote: what amplification you are using with your Vandersteens?  power amps specifically?

bummer on the wait
good that RV can rebuild.... i forgot to ask him about this yesterday...

silver lining - me personally i would take this , golden opportunity to get that second set of nice backup speakers..

my list in descending order:
7 mk2
Apogee Stage
Klipsch Cornwall
Bryston MiniA
ADS L-730
Dynaco A-25

my plan is get rid of the junkpile except the A-25 for garage and get a pair of Treo CT
i ran my 5a with Mac 202, then Ayre VX-R, then got 7, then upgraded to VX-R Twenty, traded that in on Vandersteen Monoblocks.

i will say that i have heard Quattro really sing on Ayre, Quicksilver, VTL, Aesthetix, ARC and Atmosphere amps...
with the powered bass you have such an unfair advantage in amplifier choice...vs full range amps that can drive a spike to center of the earth type bass...

i have been helping brother in law dial in his model 2 C signature and he is using a Odyssey amp from Klaus which punches way way above class, especially for a SS amp
