Deleted You will notice the difference between a prototype and a product, when you start trying to get spare parts for maintenance and repairs. Maintaining a prototype is usually as expensive as building a new one.
I understand your skepticism, but in my opinion you are being too blunt and severe.
The whole USA economy is based on prototype and small companies becoming big (start-ups). Of course it's easier in software, and really thriving in that field, but it works for hardware too. Especially for piano, that's a very capital-intense industry, attitude like yours have stifled innovation for the last 50-100 years. In particular, I find ironic that the vast majority of the piano innovations (right before they stopped) was to dramatically increase the sound volume. And they succeeded so well, that now we have the opposite problem, i.e. instruments that even at small size are too loud for apartments, and arguably for homes too. I applaud this company for what it is doing. Now it might succeed or it may fail. And if it does fail it can be for a variety of reasons including the ones which you rightly point out -- but that's the best way to start a new company.
Drew-r HZPiano On a geographical note, The Netherlands is not in Denmark or vice versa 😉.
Depends from how far you look. From Pluto, Colorado and the Netherlands are the same place. From Colorado (where I am), the Netherlands and Denmark are close enough (and besides COVID, the EU border rules make it even more so) 🤣
In any case, in anybody is interested and finds the opportunity to try one, please share.
Some of us have heard the recordings the company shared. No independent recordings, and I am asking if anybody "close enough" is interested to pay them a visit (assuming they are accepting visits)
