CA78 & 98 have an option to record audio to USB device (USB thumb drive).

I tried to record and found the output .wav file generated to the USB device is at 16bit 44kHz

I'm planning to try recording from Line out through my audio interface (which will be at 24bit 192kHz).

Has anyone tried and noticed that record from line out is significantly better?

With hi-res audio you may actually be sampling at a higher rate and resolution than the actual sound engine of the DP. And the line-out recording is prone to get electrical noise and artifacts depending on your hardware. I would suggest you to play a midi file (so that you can repeat the test later), and to record it simultaneously to external usb as wav and the line out. Take the two wave files into one of the many free software spectrum and wave form analyzers and compare the results (there are plenty of such analysis on this forum regarding VSTs). And since you are talking about a ca78/98 you should also repeat this test in pianist and sound modes to check if there is any advantage recording the pianist mode in hi-res audio.

If the .wav file to USB device is the actual source (without down sampling), there is no need to do comparison.

I wonder if modern DP sound engines only capable of 16 bit @ 44kHz

Only?
That's CD quality. Do you believe you'll perceive a difference between that and 24bit 192kHz played through the piano's speakers? Even for the pianos with the best speaker systems on the market. I'm sure even through headphones that most people wouldn't feel any difference at all (if any at all). So why spend money in that direction, for more powerful processors and whatever's needed to work at a higher quality, when the difference isn't perceivable? Especially when the latency is much more important, and the most important is the quality of the samples or modelling.

For those looking to record, there's a plethora of VSTs, but for the home user and pianists (people looking for a piano and not a DAW), CD quality is more than adequate.

As a curiosity Dexibell says: "The new 24-bit technology together with the 48 KHz sample rate has significantly improved both the frequency response and the dynamic range of audio, compared to all other digital pianos."

So, some DPs do have higher sampling rates and bit depths. Whether it really makes any difference...I don't know.

Human hearing can't feel any difference.

When you promote your product you have to have something "special" to say about it.

I guess "24-bit technology" is deemed "special". (But it's really not special at all.)

And, as always, I like to ignore the specs ... ignore the specs ... ignore the specs ... and pay close attention only to what my ears tell me. Nothing else matters.

Dexibel (and other manufacturers) are likely using higher resolution audio to sample/record instruments and other audio sources that go into the DP. But that does not mean that the same bit rate is used for the final audio format. For example, to digitally master a CD the audio is recorded and processed in hi-res audio and only at the very last step is converted to a modest 16 bit/44kHz CD format. But most humans would be unable to tell apart the hi-res audio source from the lower-res CD format. But recording and processing the audio at 16 bit/44kHz would be whole different story...
