Has anyone used this machine yet?
It looks like another next generation dual boiler lever with PID and heated group. Also a really striking design.

Gorgeous!

Raises many questions...

Servo assisted lever?
Patent phase?
And those side paddles...?

Looks more like a lever than the Rocket Epica for sure.

Curious to learn more...

The true commercial machines from La San Marco have what's called Leva CLASS to protect the lever from springing back up when there's no portafilter:

I think servo in this case means that you can control the rate of lever movement. If that's true it would make controlling the pressure profile easy. Nice idea.

If it works then it's a great idea! I already love the design especially the black version

deatails from antonio nurri:
" Our new Leva SA can feature very interesting performances:
- Dual stainless steel boilers (coffee boiler saturated)
- Thermoregulated Groups
- All temperatures are adjustable by PID control
- Integrated pump; reservoir + main water.

Thanks to the 2 paddle you can maneuver:
- Release pressure within the group head while extracting
- Flush water to clean shower
- Blind filter to clean inside group

All operations possible without touching the lever.

What do you frankly thing about that? "

was in contact with him yesterday and today

maybe someone is speaking german here:
