Does anybody played Korg Kross 88, are keys heavy and weighted there like on acoustic pianos and on expensive digital pianos? Is it good enough for playing Chopin an Liszt etudes (and recording them for competitions and radio)?
Question one can be answered from manufacturer website: Natural Weighted Hammer Action
Question two: I doubt it, besides a German test summarizing the disadvantages as "sound quality not always fully convincing" (so you need something else for the sound) and "weighted keys somewhat spongy" I simply doubt that one gets a stage piano (if that form factor is important to you) satisfying at least semi-professional ambitions in the 1000$ range. What you require is pure mechanics and that still is connected with considerable costs .
