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!

Yes, you are correct. I was hoping the OP could swap out drivers and save the shipping costs. 
I was actually thinking about the Vandy subs.

Gdnrbob,
Thanks for the spike info.
Yes we do have dealers, but they only complicate things and slow them down: they outsource repairs, and, if I have to send a speaker for rebuild to RV, it’s going to be much faster to do it direct.
JohnnyR,
Will call you today.
Thank you.
IF they are same spikes as 5a they are very nice and IMO very reasonably priced for audio jewelry- i bought 6 when i made maple amp stands for my Vintage Mac gear to bi-amp my Apogee Stages..

you can bet that was a very interesting conversation with Richard

also IF you want most of the benefit of the spike but do not want to marr floors, they also have a machined aluminum cup with felt. i have tgese on my 7

makes tweaking placement easy ,,,,

good luck on the driver - hope you can do it locally
tomic601,
Thanks for the info. 
If the crossover is faulty I will certainly fix it locally. If it's the driver, tough luck, off it goes to RV for rebuild.
Thanks to all for your advice and help.
