When I participated in a small recital held by my teacher this spring, we had access to a real lovely grand (a Shigeru Kawai) at the venue, a real pleasure to play. My teacher was a bit astonished how good I played

on this grand, much better than she had heard me doing before. I explained that it was because this wonderful grand was far more alike my digital at home (a digital Yamaha baby grand) than her big old upright, which I always have struggled with.
Anyway, since last summer I have played on more acoustic pianos in all kinds of shapes than I bother to count. At first encounter, it took me a while before I could adapt to the acoustic pianos. After a while I was able to shift from one piano to the other without even thinking about it. You get less sensitive to the difference in piano models when you have tried many ... just like learning to drive.
My digital here at home is a very good one and I play with headphones most of the time. No, this is not dangerous for my ears, on the contrary - I can turn the volume down quite a lot sometimes, just to spare my ears. Good when you practice more boring things or are in the beginning of learning something new ... I like the sound and the touch and feel. What I miss, compared to acoustics, especially the best grands, is the vibrating, physical feeling from wood and steel. Not just a big sound in my head, but also a feeling in my whole body. I also think there is a lighter action in acoustic keys, especially in the higher register, which makes trilling easier. I often also experience more physical depth then I press the keys on an acoustic grand.
Of course I would love to have an acoustic grand here in my home BUT ... I know I would not get many chances to play it. My house is small and we are 4 persons living here right now, plus two dogs ... I would get nervous and disturbed if I worked with something, er, less beautiful, like tedious exercises, and difficult pieces where I have to disassemble the piece in small, small fragments while I learn them. Must be terrible to listen to. No, that would not work. And I also hate when pianos are out of tune or when the pedals get noisy and squeaky.
So my own personal solution, for now, is to rely on my digital here at home, and then take the chance to try other pianos out whenever I get the chance.
I also conclude that the quality of the digital is essential. I would not stand a cheap, plastic digital in long terms, but the one I have does have real good action and weight. Would be even nicer with wooden keys, though ...
