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!

JohnnyR,
What exactly do you mean by "a real preamp without ICs in the path"? My preamp is quite real, and if you go separates vs integrated, you will always have ICs ( interconnects?) In the path. Or am I getting something wrong?
Also, what’s wrong with Conrad Johnson?
I have no spikes/cones whatsoever, so no. Need to buy them.
And I haven’t done the in-room compensation thing yet.

In this context, IC = integrated circuit.

I, too, am a bit confused by Johnny's post.

Yes, you need the spikes/cones installed on the speakers. Didn't yours come with a set?
They disconnect the speaker from the floor and help with clarity/imaging.
Tilt back, too, is necessary for proper imaging, soundstage, getting the tweeters at the right height.
If you don't have a set, contact Johnny. You could also get some threaded gliders from Herbie's.

nothing wrong w you PRE amp
The fact you are commenting about
how anything sounds without doing the proper set up protocols
is very confusing to your audience 
and yorself
and that would in return give you
half assed results you need to read the owners manual and get the spikes , spacers and parts to experience what you paid for
