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!

the Atlas is a very very fine match !!!
Jim White and RV are collaborators for sure to wit the built in high pass filters
keep us in the loop
the Atlas stereo and mono both have serious low end vise like control, probably worth looking at vandertones again just to see....
best

 Yes agree, solid advice........
 With Aesthetix Atlas or when changing from any amp make sure you reset the XLR high Pass Dip Switches to corresponding input impedance adjust all back to open and then set dip 3 / 5 closed for Aesthetix's proper 100 HZ x over setting.

I thought with the Atlas's built-in HPF I don't need the Vandy external HPF any more?
I also hope there is a section in the Atlas manual for setting the HPF for Vandees.
HP units are worth keeping they will sound just a bit cleaner then built ins
If you Just use the Vandersteen XLR Battery Bias HP filters switched to 3/5 into the top Atlas XLR inputs you may not need anything else anymore.

As a matter of fact I was planning to use the DAC straight into the amp.  My HPFs are RCA, rest of the setup is balanced, wanted to put them away. No point in buying another set of HPFs.
