that's so exciting! i recall posting several pictures of sauter grands in the 'piano porn' thread. super nice, i think those old germans are super incredible works of art and some of the finest being made today (along w/ august forster, seiler, steingraeber, bechstein, and bluthner).
what was it about this house that finally got you? i ask since you didn't play the exact instrument you'll get, did you play another delta? who else did you consider?
Well, Norbert of Heritage Pianos had a Sauter Omega (220cm) that had been used as furniture at someone's home for a number of years and it was at his shop on consignment. I fell in love with the sound, touch, fit and finish of this instrument. The piano was impeccable. He offered me a great deal but unfortunately, I wasn't in a position to take advantage of the opportunity.
He also had another Sauter, which was the same model as the one I eventually ordered, but again it was already sold and waiting to be picked up.
I have been passively searching for
the piano I may eventually try and get. I've tried various Steinway, Fazioli, Kawai, Schimmel, Grotrian, Knabe, Yamaha, Baldwin, Bösendorfer, Estonia and even Blüthner models. All great pianos at their price point, but the sound of the Sauter was the one for me, not to mention that Norbert made me an offer I couldn't refuse.

Cheers,
