Hi Andrea.

Beautiful performance on both keyboards, but it's really two different
kind of renderings we can hear.
Both are very smooth and nice to listen at, but something make me feel
that one recording are done in a studio and also make me feel like I'm
playing a CD on my stereo, and the other are much more "live" and make
me feel the ambience and the musicians presence in the performance.
To me it's the G-70's sounds and style who make the best impression,
Yamaha sounds way too much "studiopolished and cold" in my ears.
(I'm very tempted to add: "as I think Yamaha mostly do")

Thanks, and Happy Playing
GJ
