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!

Thanks.
Waiting for the CJ to open up.
Frankly, looking at upgrading my power amp to an Aesthetix Atlas. Not sure that this is THE weak link in my system, but it got me thinking...

(((3 out of 4 are DACs with volume regulator, the last one is a streamer  with this)))

 Bleak at best.
 Try and find or keep a real preamp without ICs in the path.
 Audio Research Ayre Aesthetix etc
 have you done the in-room compensation set up?
 Have you read the manual and done tilt back?
 Are your spikes / cones installed and tight?

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.
