I plan to play acoustic piano songs or accompaniments and looking for a natural sound with a realistic action and that led me to consider the CA49 and CA79. Clavinova is an option but heard it doesn't have wooden/realistic action.

I'm debating between CA49 and CA79 and idunno if I can justify the price difference when for me the main difference is:

1. better acoustic piano sound samples - this may not matter as I may opt to use MIDI instead of the audio signal, but if I do choose to record the audio signal, this will matter a lot

2. action - CA79 has longer keys and more realistic action

What doesn't matter:

1. Speakers don't matter at all, as this would not be used for live performance

2. All the fancy extra sounds don't matter

3. other extraneous features that may appear on more expensive models - fancy UI, etc.

Given all of this, should I save the money and get the CA49 instead of CA79 or will I regret this?

I am considering buying a Kawai (CA 99 or 79) instead of a Yamaha (CLP 775/785), but I saw some people complaining about those models on pianoworld forum (that I guess amplified the issues) and was reconsidering Yamaha (but 785 is really expansive, €1400 more than 99, while 775 is 700 less than 99 here in 🇮🇹 ).

Any feedback by those piano owners? Did you have issues? Did Kawai fixed them?
