The Domus Grand Piano does not at all require big solid state power. I can't speak to the older version though. We get excellent results with ARC 50-100 watt tube amplifiers. They even work well off the 8 ohm taps, meaning that they are pretty benign for a 4 ohm speaker.
Also, the Sonus Faber Musica which is their own house amplifier is only 50 watts per channel.
What is more important with the Sonus Faber speakers is placement and set up. They are very room reactive. Using Sumiko's "Masters" set up technique results in rather startling transformation from where users generally plop them down in the room or arrive by trial and error.
