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,
On top of Shahinians I have a pair of open-baffle speakers of local make (Noize Fabrik) and KEF LS50s.
But... I don’t like the idea of backup speakers. Might give the main pair the idea that they r entitled to a vacation :-)

Here’s a link to one of my speakers.
They are extraordinary, BUT they need the right room to play well. In my room they don’t work, unfortunately. No bass.

that link takes me right to Manaforts lawyer.... just kidding
i like your attitudes about not  having an understudy visible and yet waiting in the wings... so i have a vintage room system where i keep the backups - its really is a work room....


I had a similar trouble with my 5A Vandersteens. I sent the driver to Vandersteen who said they were fine (not what you want to hear). After pulling the tweeter, et al, I sent back the crossover and amp. It seems that in pulling the crossover, I accidentally bent a wire that was touching something else.(very hard to slide that sucker out) It was bent back into place.....the speaker sounds great now. (don’t know if that’s your problem, but just telling you of mine) Make sure when you replace everything, it goes back into the proper enclosure.
