I can certainly upgrade the on walls and center. My center especially is behind an AT screen so no issue there. My M22’s are wrapped with stone on wall so upgrade there will take some labor. Also doesn’t 90% of the dialog come from center? That’s where I’m seeing the biggest need for improvement. My M22 channel levels are actually turned down much lower than my center to try to improve dialog volume. The VP180 would certainly need an amp right?
