Breville Dual Boiler vs De'Longhi Stilosa EC230

The Stilosa at $99 is a functional beginner machine with a real metal steam wand and a 51mm portafilter that accepts aftermarket baskets. It ships with pressurized baskets that mask grind inconsistency, but a $15 non-pressurized basket swap opens a real improvement path. Its factory pump is set to 15 bars, above the 9-bar espresso ideal, which requires either a simple OPV mod or a bottomless portafilter to correct. For the price, it is a surprisingly serviceable starting point.

The Dual Boiler is in a different league. Triple PID control holds the brew boiler, steam boiler, and group head within 2 degrees independently. Programmable pre-infusion up to 60 seconds, simultaneous brew-and-steam, and a 58mm group head with access to the full prosumer accessory ecosystem give experienced users complete control over every extraction variable. The gap between these two machines is not incremental; it is categorical.

The only meaningful overlap is that both require a separate grinder, and both use a manual steam wand. The Stilosa's steam power is modest and the thermoblock requires a cool-down between brewing and steaming. The Dual Boiler steams while pulling a shot and produces consistent microfoam without a wait cycle.

Choose the Stilosa if you have $99 and want to find out whether espresso is worth pursuing further. It is an honest first machine at a price that limits the risk. Choose the Dual Boiler if you have already answered that question and want the best extraction control available under $2,000 without moving to European prosumer pricing.
