Vx700, since the Andra III are ported, have you experimented with placement distances from the front wall? I have the Andra IIs and I prefer the sound farther from the front wall (48") ... cleaner bass, more depth, 3D, air ... EW recommends 24" and I found the sound flat and dark.
If I were to change speakers now, I would add Magico V3 and Revel Salon 2 to my list of potential replacements. Planning to check out the Magico's at local dealer when time permits.
I believe when discussing speakers within a price range, it's a matter of personal preferences and not better or worse. I know several individuals sold their Andra II for the Is. They prefer the crossoverless sound of the drivers.
IMHO, I believe the Is sounds different is due to lack of bass ... similar to mini-monitors. One of the individuals that switched had to add a sub to compensate for the loss of bass.
