I think the Sympathetic Resonance adds a ton of realism to the piano. I have a 7'5" Yamaha C7 grand piano here by way of comparison. The new SR is a great feature when dialed in to an appropriate level.
For anyone who says "they can't hear it" - try this experiment:
- load KRONOS German Grand
- turn on SR and set level to about 30 (or higher if you want)
- play a CMaj triad in the octave below middle C (C3 - E3 - G3) and hold it (not with sustain pedal, with your fingers)
- Wait until the notes die out completely
- then, while continuing to hold those keys down (so that the "felt is off the strings"), play staccato short notes of a CMaj arpeggio in the octaves above the held notes, i.e. C4, E4, G4, C5, E5, G5, etc.
- Listen to the resonance of those 3 held notes ring out - very cool!
It's not going to do anything for a rock piano mixed into a track or live band, but for solo piano work or lightly accompanied new age/classical/film, it definitely adds realism, IMO.
