The EK43S leans clarity and sparkle; the Robur S leans syrup and body. Pick the cup, not the machine.
The counter’s vote
Looks barely figure in either machine’s record — the counter can sit this one out.
EK43S: Workhorse industrial aesthetic; no kitchen-approval talk, but pro-heritage look commands respect in espresso circles.
Only the EK43S: a single-dose workflow.
Only the EK43S: a documented burr-swap scene.
Where they tie: built to last · quiet operation — don’t let a spec sheet invent a difference.
So — which one?
Take the EK43S if —
- Bright, separated cups are the goal
- You brew more ways than one
- You weigh every dose anyway
- You want a chassis that grows
Take the Robur S if —
- Syrupy, traditional cups are the goal
- It has to just work, every day
- Espresso is the job, full stop
- Every dollar has to earn its place
Both columns reading true? Take the one your gut already picked — then stop reading reviews. Fresh beans will move the cup more than this choice will.
Known weak points
EK43S
Burr alignment drift requiring recalibration; bearing wear on high-use machines; variable QC on newer units relative to vintage models
