I too have found my EK43S is not a one trick pony. I do not know how well aligned it is but it will at present grind for an EK shot or a conventional espresso that is thick and unctuous. As a matter of fact I am enjoying one of those while typing this. I do not know if mine will grind for a pour over as I have the Turkish burrs in mine and did not buy it for that use. I may try it sometime but have a KMonCon that will do that well if I choose to. Over the time I have owned mine, which is not all that long, I have seen several comments about it only being able to make thin but tasty shots. I fully suspect that these folks do not own one or maybe have never even had a shot ground in an EK43S, it can do both very well. I cannot vouch as to whether the big EK can do the same but if it has had the chamber and prebreaker updates like the S I suspect it will. Can the EK43S be improved with some TLC? Certainly it can and kudos to Terranova for his work in advancing the capabilities of these grinders! Eventually I will get around to checking its' alignment but retirement is keeping me too busy for the time being to worry about such a mundane thing when the machine works so well.
I did recently readjust the zero point on mine but it was a very minor change so suspect it was similar to the changes in grind I saw as my KMonCon broke in after using it for a while. Likely some high spots on the burrs that were polished off by the beans with use.
I see many recommending the KMF MAX to folks that have floated questions about grinders on this site and know it will be a fine machine, but, 1. It is not yet available (soon I hope) 2. When it becomes available the chances of winning the lottery for one are relative to how fast your internet connection is and the luck of being in the right spot in the queue when they do come up for sale. A person could wait without coffee for a very long time before getting a grinder.
Will I try to get a MAX when Denis makes them available? Darn right, he makes great grinders, but I have been trying to get a flat since the second batch was offered to no avail as my internet sucks. Maybe my luck will change in the future but even if I get in line to own a MAX I doubt I will be throwing rocks at my EK43S. It is a wonderful Titan Flat grinder. Don't sell it short.
