Friends,
Here are a few more clips of its sound, played by a colleague of Josephine. Sorry for the many cuts, that's when they were talking.
Sorry for the bad recording quality (smartphone), and the Chopin was recorded from inside the piano. But the clips do show a bit more of the tone, and perhaps the action (some fast passages at the end of the third clip, repeated notes, etc).
I really like the purity of its tone, in particular. It seems to me that a number of century-old Blüthners tend to have a tone that I would call "wobbly" (well maybe not just Blüthners!) but this one doesn't. And when they don't, then I find the tone to be magical, like that "opium" sound that Cortot famously strived for. I'm probably exaggerating😅 but let's just say I really like what I hear.
