That is looking good and if we should add competitors to the Korg system in this thread, I seriously think this one is a good idea:
Interesting recorder, but I do not think it as a competitor of Korg+2 good condenser mics (as I
hope my K2 Rode are).
1) With Kawai (if you use it with their mics. I've read that one can use it with external mic, but
at this point the costs are equal with my systems, and remain the minor quality of 2)) you are forced to take the sound very near to the piano, and you have to add digital reverb.
I think it will be better to try to capture the natural sound (piano+ambient), without adding reverbs
to obtain an "ambience".
2) The a/d conversion stage doesn't seems at the level of the Korg one (impressive, with its 1-bit SACD quality or PCM 192 khz-24 bit).
If one think only to a recording to be heard in mp3 compression with PC monitors, all these
machines (both Korg and Kawai) are of too much good quality and price.
But I'm interested also in recording quality by-itself (and generally in hi-fi)...
But I think (as Mindenblues) that also with my choice (2 good tube no phantom powering mics + a good a/d), a weakness could remain: the mics. pre-amp, surely excellent neither in Korg nor in
