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!

Bob,
I broke it a bit myself. I thought there were metal inserts and screwed the cones in without looking. My bad.
However, rest of the thread is fine. 
And I can make the inserts if they are flat and fit into those depressions on the bottom.
I will also request Richard for those spares.
Can you guys please measure the gaps between the speaker bottom in front and back of the speakers and the floor? Thanks!

You don't need this.
If/when you put in the threaded inserts, you will thread your spike stud into it. Then, depending upon your floor, you will adjust each spike to give you the proper tilt(as per the Vandy manual), then tighten the jam nut to secure.

However, rest of the thread is fine.
There is no thread in there. Hence the need for threaded inserts.

Bob,
What I want to know is how much tilt does it usually require to correctly position the speakers.
Hence the question.
And yes, there is thread both in the front holes (cones) and in the back (Spike).

As far as length of bolt is concerned, it depends on how un-level your floors are. In my 100 year old house, things are definitely out of plumb. Thankfully, I didn't need to alter the spikes, so I doubt you will.
If I recall, the spikes have about 1.5-1.75 inches of thread exposed before the spike.

the tilt can be found from the manual !!!!!

which you can down load from the Vandersteen website

for free

you need to follow isoquant lines depending on two important variables: distance from acoustic center of speaker and height of your ears in the listening position

those will tell you how many washers to put under each cone
