It went well. and so did the third and fourth đ we ended up going there every day. new observations included that the 138K upright was sublime in terms of its texture, brilliance, and projection. and the SFM magnet action felt better than many grand actions I've played, so I was dumbfounded by how nice that was. We resisted the temptation to buy it though, given we already have two acoustics.
My wife and I also had a nice evening, where it was a quiet, intimate setting in the museum, playing their historical instruments. There were lots of them, and we felt like we were in a wholly different era. Especially since their palace is overall non-restored, non-renovated.
Lastly, the more we met with the Steingraeber family, the more we appreciated their down-to-earth, mom and pop vibe. To say they were very "human" is an understatement. They approached their business with a lot of humility.
When we think about premium piano makers today, very few are still family-owned, and not purchased by a corporation or private equity. I think if you want to be part of the Steingraeber legacy, and feel like your piano is part of a bona fide family, and one that is "built in a home" - Steingraeber is it. There's that emotional attachment one has with their product, and their ecosystem as a whole.
