Got my Argos today and it looks and feels so much better than I expected. It’s super tiny, beautifully designed and setting it up was very easy. Filled it up with 40GH/40KH water and it got to temp within 5 mins or so. Flushed for a bit to clean out the water path. Pulled a shot with some washed Ethiopian beans 18:40 and it tasted really nice and soft, lots of nice lemon acidity, very nice floral notes and some white sugar sweetness. This was in spring config with the 6 bar spring. Also got the analog pressure gauge and digital transducer. Need to install those and play with the app over the next few days.
Keurigs are made for convenient filter coffee while the Argos is made for espresso. I believe Keurig has “espresso blends” but the machine isn’t capable of creating the pressure needed for true espresso so what you get is just a stronger tasting filter coffee.
