Roland HP603 vs Kawai CA67 vs Yamaha CLP-585

[edepot]

I recently got a Roland HP603, and will probably use a headphone with it.
I noticed that the only difference between HP603, HP605, LX-7, and LX-17 are the speakers. But using a headphone, EVERYTHING IS THE SAME between all four models. That means it is a great deal because I am getting the same key action and same sound modeling technology as the higher models (even the flagship LX-17).

I was wondering how it compares to the Kawai CA67 and Yamaha CLP-585 (or maybe even the Casio GP-400) on a headphone. I know the only Yamaha that has the same type of good key action is the CLP-585 (the rest can't even compare). Similarly, the CA67 (CA97 for soundboard) has great key action, but the sound is sampled, not modeled.

For the sound, I hear the Yamaha is too synthy or fake. With Kawai sounds pretty great (but sampled), and Roland's SuperNatural (their tech name) good, but greater if you change the PianoDesigner to make the bass less mellow.

I took a video of the unboxing and playing the keys (not through line output). Can professionals tell me if the sound is good? Note that the sound is NOT changed (PianoDesigner) in the video. I will put another video with the PianoDesigner changes (that I got from the net) in another video. But I wanted other's opinion if the sound is good or not by default.

Here is the video:
