The group of the new ACS Vesuvius Leva is said to heated by two PID-controlled elements.

I'll have to check out Gwylim's videos.

My go-to reference on lever efficiency is il barista Dritan Alsela, at 10 cups in 6.5 minutes on a 4-group machine, with beautiful latte art. A lot of this time is dealing with milk, would likely be much higher output with just espresso:

Lelit MaraX Review perhaps not exactly the same, but similar.

It definitely is, about 220W of heating capability...there is no thermosyphon, or dipper. The brew boiler is connected to the group by a single pipe. Depending on how you set it up, the group is at the brew temp you want (there are other options) and maintained by a PID reading an internal sensor in the group.

The brew boiler is controlled by another PID

That statement has to be proven when the protoype exists.

He also once stated that the Strega is " a pumpmachine with a lever attached for festive decoration ".

Next thing he made a lever with a pump for ( pre)infusion.
So maybe now it' kinda like a Cremina with a Bosco group.

Well, I have to say based on personal experience that the LR pump is most definitely *not* mere decoration. I continue to enjoy and appreciate my LR every day.

I am waiting on the edge of my seat to replace my pre-mil Pavoni Pro. I've had several vintage levers in the past but I'm done with having to constantly fiddle around with old things

That's what I told my wife.
I am now living out of a hatchback, drinking coffee from petrol stations.
I should have settled for a La Pavoni.
