To me this seems normal !

Someone else can hear this problem ???
As I said, yes. And someone on another german forum is complaining about it also (he made the video).
I have to admit that I used decent headphones, too. But we are definitely not talking about "normal" resonance - at least not of pianos in general. It's only one particular key (the lowest C# on a 61), and it's not even a resonance of a straight octave or other "simple" harmonics. It's a clearly audible tone (the note A in the highest octave WITH dampers - i.e. the second highest A on a 88 keyboard).
I am quite sure that even a Steinway doesn't have this type of resonance on a single note normally.
But: as obviously all velocity layers are affected (which means more than only one sample), it seems like either
a) something resonated in the recording setup (part of the actual piano, or something around)
b) the damper on the A key was defective or inadvertedtly slightly off-position during recording
c) there is a wrong sample index stored for some supplement/"background" samples like string resonance or harmonics...
In the youtube video it's hard to hear, though...
