I came across a used Kawai CA-61 for $2100. Is this a good price? Is this worth purchasing given you could buy a new CE-220 or maybe CN-33 for around the same or less? If it's too much, then what would you consider to be a fair price?
The CA61 was a US-only model that essentially added the CA91's soundboard speaker to the CA51. This instrument also features the AWA Grand II wooden-key keyboard action, which is still very highly regarded.
However, that generation of CA instruments (CA51/61/71/91) utilised the older 'Harmonic Imaging' sound technology, before Kawai adopted the more modern 88-key piano sampling process. So while the CA61's keyboard action and speaker system are very good, the core sound is rather dated.
The CE220 uses the same wooden-key keyboard action as the CA61, but does not include the soundboard speaker. However, it does feature the vastly improved 'Progressive Harmonic Imaging' sound technology, with 88-key sampling, allowing for a far more expressive and realistic sound.
The CN33 also uses the same sound technology, however the keyboard action is quite different - the plastic key 'RH' action.
Even though the CA61's soundboard speaker is a premium feature, I don't believe the instrument is worth $2100, especially when a brand new CE220 (with better sound technology) can be purchased for under $1900.
If you're keen to purchase a Kawai, I would also consider visiting your local dealer to see if they would be prepared to offer a good deal on the CA63, which would be a further step-up from the CE220.
I hope this helps - best of luck with your search.
