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,
Thank you for your response. 
What can you say about Treo?
A lot easier logistically for me, and costs less - $4K, almost unused.
Thank you. 
Also, can the filters be fitted between a source and an integrated amp? 
That is on top of the fact, that the filter on sale is for XLR ICs...

i was not poking at your amp
the powered sub and hi pass filter take the load off any amp you choose to use

MF makes fine sounding products, his all class A 100 watt battleship is still one of the best amps i have ever heard period.

i had a MC202 driving 3a Sig for a decade
getting the autoformers out of the way is important but i upgraded to 5a first then an Ayre amp replaced the Mac.

CTsooner and gdnrbob could coment extensively about Treo

again if it were me - Quatro all day long

tomic601,
Thanks for your comments, no offence taken anyway. 
If it is an integrated, I am not sure I will be able to fit those filters...

Your integrated amp has pre out's (according to a quick Google), so you are good to go. You can buy fixed crossovers for approx. $200 in RCA.
You can also buy them directly from Vandersteen.
