I am two days into owning one myself. Singles were like my Silvia and needed less tamp/coarser grind but i gave up as i take a double in general. Im using my VST double basket so Im comparing apples with apples form the Silvia.
Same deal you mention with the steam from the hot water but i dont think it would be a surprise (Ive not checked the plumb route) but expect like having to do a cooling flush its the same deal.
My pressure at brew bumps up to just over 10, but I am guessing this is about right allowing for the measure point to the actual grouphead being a drop off.
My milk texturing took a turn when i just did a number of pitchers of water/soap drop and finally followed good guidance on this forum with care on the initial stretch then just plug the tip a little deeper and move towards the side. Its been pretty good though not perfect.
I like the manuals that come with it, theres been some thought into them and they explain more than i was expecting looking at some of the other download pdfs so Kudos to VBM or ECA whomever is responsible.
Cant say Im that positive on the new badging.
