my 2 groups Lusso just arrived from 1st line. I'll be dialing down the P-stat and start playing with this machine. The video from Shaun inspired me into getting this machine.
I think you are going to really enjoy the machine. There's so much to play with, preinfusion is my little rabbit hole right now especially after playing with the Slayer machine on the weekend which made me rethink lever interaction with the coffee bed. Very, very cool.
I'm finding the ability to pressure profile and preinfuse on a realtime basis, dependent on what I feel with the coffee, is allowing me to drive the lever forward in an exciting direction... down, down, down into the lever rabbit hole.
Post up if you have any questions on things. I don't know your espresso background or anything about your coffee experience but I will mention it's a good idea to get yourself a kitchen scale that measures to the .1gm level and start weighing every dosed basket load prior to the pull, even as few as 4-6 beans can make a difference in the cup/pull strategy. Crazy I know, but it's fact.
Here's Slayer's site to get a sense of their 'two stage' grouphead, the difference in the cup as based on brewing technology comparing traditional 9 bar extraction versus 2 stage (2 bar, then 9 bar, then 2 bar in whatever timeline ration you want) is so noticeable it's two different drinks - how different is up to you as the barista:
