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!

@gdnrbob, congrats on the Ayre amps!!! I know you were itching to try a pair. Let us know how they work out for you.
Tom,
They also sound incredibly natural. But. The room thing is really essential.
I do have two extra amps (a Stingray II (a keeper) and an ARC CA50 and 3 extra pairs of speakers (all on sale). So I guess you can say I do have a spare system. For now ;-) But in my second location - I have to confess - I am using a single Bluetooth speaker (a Marshall Woburn, replica of Marshall guitar amps). No hifi, but easy to use and good for easy listening and movies. And HUGE ported bass :-)

Stingreen,
Thanks. Will keep your advice in mind.

I haven’t listened to any open baffle speakers, yet. Seems like they should be on my ’to do’ list, along with MBL. 
I am currently into non-crossover designs, namely Zu. They are quite impressive for the money. Not up to Vandersteen, but pretty close.
Also, Stringreen’s comment is a good one. Maybe when you get to sending out the driver, see if there is anything amiss in the wiring. Perhaps something got bumped out of place when they were shipped.
@tomic601 , and Nycjlee, I have great expectations for the Ayre( and the McCormack). I will post when I get things up and running.
The Sound Anchor stands arrived and I have to undo some old shelving, patch and repaint the areas before I set them up, so it will be a little while...
It’s never easy, is it?

Bob,
Like I said I will follow Stingreen's advice and carefully inspect everything. I have no intention of sending the driver overseas and learning that it is in perfect working condition :-) JohnnyR suggested a very simple, but very effective way of checking driver's performance: taking it out and connecting it directly to speaker cable at very very low volume so as not to damage it.  This method will demonstrate the defect (IF it is defective) instantly. All effective things are oh so simple :-)
And kudos to JohnnyR for taking his time to help.  It was a pleasure. 
Well, it's the driver. Took it out completely, checked it, it's off center. 
The seller suggested to take the speakers back, contemplated his offer, decided I want to keep them. 
So next week the driver is going to California.
CJ pre is burning in with a new Tesla tube. 
Will probably look for a Golden Lion Genalex, as they suggested on a CJ owners forum.  The Vandies have a somewhat dark sound in my setup Ann's room, so the Golden Lion will probably make it brighter, closer to neutral.
