Which levers are HX, taking line pressure for preinfusion

Hi lever lovers,

As the title, which levers need to be plumbed in to get line pressure for PI (and extraction)?

Thanks, best Robin

If you are including vintage levers, the Brugnetti Aurora falls into this category.

Is the Londinium L1 also one of them?

I will add two to the list

Victoria Arduino Athena Leva and Londinium 1-P (I think it's now renamed to Londinium-I). Londinium-1 used to be their 1-group lever with a vibe pump (now replaced by R24) and uses boiler pressure for preinfusion.

Is the Victoria Arduino Athena Leva available in a one-group version?

The new Londinium 1 Compressa relies on line pressure for pre-infusion. And like the rest of the Londinium line, it uses an HX-fed thermosyphon to feed the group.

The "coming soon" Lapera espresso machine is (being an upgraded version of the Aurora).

Bezzera B3000AL is another HX fed, one group lever.

This is the one I'm excited about.
Does anyone know how to find specs on the aurora? Are they plumb only? What sets it apart from other levers?
