I posted in another thread that I've converted to Ivory. It's vastly superior to the native Clavinova piano sounds. (And here I was thinking I just needed better speakers to improve the piano. Wrong!)
It's a bit of a hassle to deal with the extra equipment (laptop and a soon-to-be-acquired Presonus box). But the results are so breathtaking that I just can't go back to the Clavinova sounds.
With that in mind, I would rethink my piano acquisition:
I bought a CLP240 three years ago. (Today I would likely get a CLP340 or 440.)
I could have spent less by purchasing the mid-range Yamaha console, like the YDP160/161, though it would be hard to part with the appearance of the Clavinova. The polished finishes are not available in the Arius line.
Or maybe I'd go for the CLP430 for its polished finish and GH3 keyboard, and still not spend too much.
That way I'd get the console I want, and I'd use the Ivory sounds, which Yamaha cannot match.
The only thing lacking would be half-pedaling. Ivory 1.x lacks that. I didn't realize how much I used it while listening to the Yamaha sounds, but now that I don't have it I miss it (for some pieces). I think Ivory 2 has half-pedal. But I'm not ready to buy Ivory yet again just for that. (But Christmas is coming ... one can hope.)
