Ok, I've just had a listen over headphones.
I see what you mean - the sound does change slightly at that A, but it is subtle. But I wouldn't call it "dud" samples at all - it's just slightly different, that's all. To me, it still sounds sweet, just a little more mellow than the notes before it.
However, it is expected for the sound of a piano to change across the range - though, a little more gradually. When I play a piece, I don't hear the sound get "dull" in that range, I just hear the sound change as you go up the piano, really. To me, it sounds fine.
And, I only noticed a change in sound at this point on the main "Grand Piano" sound - not on the Classical Piano, Jazz Piano or Rock Piano sounds.
Are you being too picky, or am I not being picky enough?
I don't know! All I know is I'm primarily a pianist, and I love it!
Still, it's funny how different people have different opinions on it. I read some of the reviews at harmony central - generally they were very good indeed, but some weren't so good. At least one compared to the P200, implying that the P80 is a smaller & cheaper alternative to the P200. To me, (having played a P200) - I *much* prefer the P80 - the piano sound is so much better! I don't like the sound of the P200 so much at all (the action is very nice though).
Still, each to his own!
