What should I upgrade first?

Bottomless Portafilter — La Marzocco machines are high performers, and a 58mm bottomless portafilter lets you see exactly what the machine is producing. Paired with good puck prep, it's the clearest window into extraction quality you can get.
58mm Precision Tamper — A flat-base barista-grade 58mm tamper ensures a level, consistent tamp every time — essential for getting the most from a machine at this level.
Distributor or 2-in-1 — At the La Marzocco level, puck prep consistency matters. A quality distributor or 2-in-1 tamper and distributor removes one of the last remaining variables and ensures every shot starts from the same foundation.
