Yes, i am referring to the sound quality of the speakers on these youtube videos.

I don't know whether the guy massaged the sound after recording them, but they sound fantastic.

it's also interesting to watch how he maneuvers these huge speakers inside tiny Tokyo homes.

I'm a big fan of this guy's channel!  His work too. SOme of the finishing he does is just drop dead gorgeous like one of those JBL Paragons he did. It looked like a giant Koetsu Urushi!

Great SQ, sound as DSD files to me, not a CD.
Also I noted:
- the room is huge and there is no acoustics or reverberant sounds in the sound showed in the video.
- the camera man walk around the room and the sound perspective is always the same.
- at 14:05 the camera even leaves the music room and the music continue to play at same sound intensity.
- there is no mikes in the room so the camera mike would mandatory to show many sound differences, but the sound intensity is always the same.
- at 15:00 with the choral voices of Michele song one hears perfectly the botton sound of the recording, again there is no the slightest acoustic perspective of this huge room, the sound of the video is totally synthetic.
- the camera gets too close to the speakers but the sound is not strong because the sound was added later.
- the woofers cone dont move.

Conclusions:
Its a direct sound recording from a SACD or hardisk add after the video was made.
The camera man is very good.
The second video from Paragon, sound as real time music.

The Kenrick facility are huge:
