Okay, I went ahead and tried the samples, here are my first impressions.
I tested the library with liquidsfz on linux, my old clavinova clp115, and a pair of sony headphones, which is my usual setup, nothing fancy.
I first played my test MIDI track a few times, which I know very well 'cause I recently tested several VSTs. Then I proceeded to play each sfz with my piano, switching back and forth.
Now, I'm not a big fan of pianoteq, but the first surprise was that dore's samples actually sounded better. Of course, there were limitations in sustain and playability, but the timbre itself seemed fuller. It might have to do with liquidsfz vs pianoteq player or just my personal taste.
All in all, very interesting, I'll post my notes when everyone is done.
