After M/L Aerius i

I really enjoy my Aerius i's. I'm wondering if moving up to a different Logan will sound better? My room is 14' X 15' , 12 foot ceilings. Jadis 100 watt amp. I enjoy modern jazz & classical. Volume is not what I'm after. What say you?
I'd check if they've established pannel production plant in China before moving any further...

The Aerius is a real gem.
