He got an interesting idea for this video: he is using the Yamaha Grand Piano CFX piano sample of the Yamaha Clavinova CLP 675 as a reference point
Needless to say, the Clavinova kills the three smaller keyboards.
Thanks for linking to this video.
Unfortunately this comparison is invalid or is the oldest trick in the audio sales business.
Clavinova's sound in this demo is obviously compressed and louder. The trick in the audio biz is to make the more expensive equipment just very slightly louder.
Clavinova's actually have two compressors in their audio path:
1) standard mixing desk audio compressor
2) Intelligent Acoustic Technology (IAT) proprietary compressor that is somehow controlled by the pianist's technique of fingering and pedaling
I think all Clavinova's have IAT switchable to various levels, but only CVP models have explicit control of the Master Bus compressor. All cheaper models have the main bus compressor fixed and rolled into the "Room" control.
Anyway, this Clavinova's sample was obviously quite brutally compressed to the level called in the USA "FM radio mix". It would be extremely obvious on the percussive sounds of e.g. hi-hat or snare. It is also very obvious on something like nervous finger nail tapping on the table that sometimes gets picked up by microphones.
I re-watched his video and he only used the rhythm tracks with a drum kit on the cheaper keyboards, but on Clavinova he only played a pure piano sound.
I don't think that Jeremy was doing this on purpose. I just think he's a trained musician by trade and doesn't have an idea how to conduct a proper level-matched

Relevant somewhat technical articles about the "master compressor" in Clavinova's:
https://en.wikipedia.org/wiki/Dynamic_range_compressionhttps://en.wikipedia.org/wiki/Loudness_warEdit: The above message may be somewhat too analytical. Let me try to rephrase it in a constructive way:
If you feel that the sound of grand piano from the Clavinova is somehow obviously "better" you do not have to spend money to get that sound. You can get a very close approximation of it by recording the sound from your economy keyboard into your DAW and then experimenting with various settings for the dynamic range compressors that are available in nearly every DAW in existence.
