I have heard both the Beethoven Baby Grands and the Mozarts, but not the same day. In both cases electronics was Primare. For what I recall, Baby Grands had more authority, extension, definition, detail, and tightness of bass than the mozarts. For a room your size I'd recommend the Baby Grands. Regardless, Vienna speakers have a bit of a wild impedance curve, therefore they need to be driven with high current and relatively high damping factor amplifiers lest they may sound plum in the bass region and somewhat too warm overall. Certain class D amps seem to work particularly well with Vienna speakers. G.
Vienna Beethoven Baby Grand vs Mozart Grand
I would like to hear how these differ in sound. I have
read random posts that state they sound quite different
from each other.. My room is 12.5 x 30 with 10 foot
ceilings. My speakers would be on the 12.5 foot
dimension and I would be sitting about 9 feet back.
Thanks!
