Two of the most-compared machines in the $450–$650 range — one bundles a grinder and auto-tamp, the other bets everything on a commercial-spec portafilter. Here's how they actually differ on paper.
The $170 price gap comes down to one decision Breville made and Gaggia didn't: whether to put a grinder inside the machine. The Impress bundles a 25-setting conical burr grinder and a motorized auto-tamp, so the $619 price is effectively "espresso machine + grinder + tamper" in one box. The Classic Pro Evo's $449 buys the machine alone — a separate grinder (typically $150–$300 for something that won't bottleneck it) is a required add-on, not optional.
The trade-off runs the other way on the portafilter: the Classic Pro Evo uses the 58mm commercial standard, which opens up a much larger aftermarket of baskets, bottomless portafilters and accessories than the Impress's 54mm size. For anyone planning to upgrade parts over time rather than buy a new machine, that standard matters more than it looks on a spec sheet.
Per published specs, it's a 25-setting conical burr grinder, which is a genuine grinder rather than a token add-on — but a separate standalone grinder at the same price point as the difference (~$170) will typically offer more range. It comes down to whether you value convenience or maximum grind precision more.
No — the Impress uses a 54mm portafilter, so 58mm commercial accessories aren't compatible. That's the main trade-off against the Classic Pro Evo for anyone planning to buy aftermarket parts.
The Impress, on paper: its ThermoJet boiler is rated for a few seconds to temperature, versus the Classic Pro Evo's traditional single boiler, which typically needs several minutes.
