Dan, have you been able to measure the pressure output at the PF from your Microcasa? Or Karl, have you tried to approximate the characteristics of the Elektra shots by pulling a shot with lower than usual effort on the Cremina?
I'm looking into getting a lever machine, and am currently focusing on these two machines.
Thanks,

Mark,
I will let Dan address the issue of measuring the pressure out of the pf. From what I recall reading your suggestion may be correct.
It has been suggested to me in other discussions that I could adjust my technique on the Cremina to more closely approximate the taste profile of the Elektra. I have not had that result. Varying the grind, using more and less pressure from my arm and having differing times for pulling shots do make a difference on the Cremina but the differences I taste all fall within the Cremina profile of rich texture, thicker mouthfeel and more crema. Keep in mind that these are the highest priorities for many. They are secondary for me to taste clarity and individuality.
I can give you an even more "naive" suggestion. I think the Elektra people "engineer" their machines for a certain taste profile. In other words I suspect the unique taste profile of Elektra is caused not simply by low brew pressure but by a collection of interconnected engineering decisions (that I could not begin to identify). I have never had a shot from an Elektra Semiautomatica but I "translate" Jim Schulman's review to say that that those shots are similar in profile to my Microcasa. I wonder but have no idea about Elektra A3 shots.
The only other experience I have is a few shots I pulled on a Gaggia Achille that cannonfodder was kind enough to loan me for a few days. Its shots were to me much closer to the Cremina's. My simple-minded interpretation is that there are engineering trade-offs and that Gaggia and Olympia choose the values of crema, thick texture over purity of taste. This makes sense also if one considers that classic espresso is made with a blend of beans and not from the SO's from which I am trying to extract singular flavors. In a commercial cafe one wants consistency of quality and not the erratic singularity I am intrigued by and searching for.
