Good to see a second board implementing the true isolation methodology for mounting

What does this mean?
My personal board, the J-01 uses exactly this type of mounting as well. Build stream available on YouTube

Cool stream. Was cool hearing about all the design decisions. Why do you prefer this method? I did a quick search but I didn't find much.
it sounds good but doesn't feel much better than any normal sandwich or top mount board
at least in my experience, i haven't used jae's board
Replying to all of you here.... so wall of text inbound.
It basically feels like a softer sandwich mount. The plate effectively is raised only be the nitrile rubber and penned in from above so it sits on a “skirt” of the gasket around the entire edge of the plate. This means it has some “give” - but is not what you see in terms of flex with other gasket materials.
The use of gaskets have two main aims and depending on the implementation you can bias it in one favour or the other, or create a balance (think front / rear break balancing on a car), with the two options being sound and flex.
This implementation is to heavily favour the sound element by removing any contact of the plate or pcb from the case. On top mount for example the plate can reverberate or vibrate from normal usage and have the sound transferred to the case. This can (but doesn’t always) cause case ping. The idea behind the isolation here is to remove that entirely, and therefore allow sound to be tuned better, whilst adding a small amount of flexibility where the plate rests on the skirt.
In essence it feels like a softened sandwich mount so it’s highly consistent across the board in terms of feel. It’s isolated from the case completely so all the sound you hear is the switch and plate and cap materials. Which then allow you to look at the sound itself.
The inside of the case then becomes a resonance chamber - like the internals of a guitar. You can change the internal shape of the case to change how the board sounds.
If you listen to the J-01 first proto, the sound is slightly higher pitched on the keys to the left and right due to the internal cut out of a chamber not expanding across the full 60% area. It’s tiny in terms of timbre change, but it’s there. For rev2 of the proto, I’ve expanded that chamber across so all keys will have the same sound as the alphas do in the video (or be much closer).
Hope that helps - happy to chat about this if anyone has any further questions.
