Description
The De’Longhi La Specialista Opera EC9555M is a semi automatic machine with an integrated grinder, a mechanical tamping lever and a commercial style steam wand. De’Longhi specifies a 15 setting built in grinder, a 19 bar Italian pump, Smart Tamping Technology, three selectable infusion temperatures under Active Temperature Control, and a cold extraction function. It measures 14 inches deep, 15 inches wide and 17.5 inches tall, with a listed capacity of 67.6 fluid ounces and a weight of 28.11 pounds.
The Opera sits at the top of the La Specialista line and is aimed at the same buyer as Breville’s Barista series: someone who wants the portafilter workflow with the grinder built in and the two hardest beginner steps mechanised. What distinguishes it from that competition is the pump description and the temperature control, both of which De’Longhi documents more precisely than most.
The 19 Bar Pump and What De’Longhi Actually Claims
Most listings quote a pump maximum and leave the impression that the coffee is extracted at that pressure. De’Longhi does not. The manufacturer states that the 19 bar pump delivers low pressure during pre infusion and the optimal 9 bars of high pressure during extraction. That is the correct description of how espresso is made, and it is the most honest pressure claim on any listing in this catalogue.
The practical significance is that pre infusion and extraction pressure are controlled separately rather than the pump simply running flat out. Low pressure pre infusion wets the puck evenly before full pressure arrives, which reduces channelling and is one of the features that separates a serious machine from an entry level one. The De’Longhi EC9255M lower in the same line shares the architecture.
Grinder and Smart Tamping
The built in grinder offers 15 settings with single and double dose selection. Fifteen is fewer than the 25 or 30 offered by some rivals, but what matters is the granularity within the espresso range rather than the total count, and a purpose built espresso grinder concentrates its steps where they are needed.
Smart Tamping Technology is a lever the operator pulls to tamp the dose mechanically. As with Breville’s assisted tamping, the value is repeatability: an even, consistently pressured puck every time, without the mess of a loose tamper and without the technique. The listing does not state the applied pressure, which Breville does publish for its equivalent. Owner feedback identifies one real drawback: the grinder compartment is not removable, which makes deep cleaning awkward and matters if you switch between oily dark roasts and lighter beans.
Active Temperature Control
Three selectable infusion temperatures allow the brew temperature to be matched to the bean. This is genuinely useful and under appreciated: lighter roasts generally extract better at higher temperatures and darker roasts at lower ones, and a machine with a single fixed setpoint forces a compromise across a whole shelf of coffee.
What the listing does not give is the actual temperatures of the three settings, or the stability band around each. Without those figures the feature can be described but not evaluated. It is still more control than most machines at any price offer, and it is exposed through a single button rather than buried in a service menu.
Steam Wand, Cold Extraction and Milk
The steam wand is described as commercial style, meaning a bare metal wand rather than a panarello sleeve, with steam pressure sufficient for microfoam and latte art. That is the correct hardware for anyone who wants to learn milk texturing properly. Published owner feedback raises a specific caution: the wand can overheat milk if left in too long, which is a consequence of having real steam power and is managed with a thermometer or by feel until the timing is learned.
Cold Extraction Technology is listed as a separate feature, and owner feedback reports it produces a cold brew style drink in under five minutes. As with every fast cold extraction system, this is a pressurised cold or low temperature extraction rather than a long steep, and it produces a different result from twelve hour cold brew. The listing does not explain the mechanism, so the specifics remain unverified.
Footprint, Water Tank and Daily Handling
This is a large machine. At 15 inches wide, 14 inches deep and 17.5 inches tall it needs a permanent counter position, and the 17.5 inch height has to be measured against wall cabinets because the bean hopper is filled from the top. At 28.11 pounds it is not something that gets moved out of the way, which is a real consideration in a kitchen where counter space is shared with other appliances.
The 67.6 fluid ounce capacity listed in the data is presumably the water tank, which at 2 litres would be generous and appropriate for a machine of this size. Removable and washable components keep daily maintenance manageable, though the fixed grinder compartment noted by owners is the exception. Anyone weighing footprint against features should compare the considerably smaller Breville Barista Express Impress, which offers a comparable grinder and assisted tamping in a narrower body.
What the Specifications Do Not Settle
The structured data on this listing is unusually poor for a machine at this price. Two attribute rows read as “Capacity 67.6 Fluid Ounces” and “Item Weight 28.11 Pounds” in both the name and value fields, an importer parsing failure. The manufacturer part number is empty, and there is no voltage, no wattage, no country of origin, no first availability date and no warranty term anywhere in the data.
Missing product facts include the three infusion temperatures, the tamping pressure, the portafilter diameter, the bean hopper capacity and the cold extraction cycle time. The 67.6 fluid ounce figure is presumably the water tank, but nothing in the data confirms that rather than, say, a milk carafe. At this price those omissions are worth resolving from the manual before purchase.
Who It Suits
The Opera suits a buyer who wants an integrated grinder, mechanised tamping and a real steam wand, and who values selectable brew temperature enough to pay for it. The honest 9 bar extraction description, three infusion temperatures and a commercial style wand make it a machine with genuine headroom, and the mechanical tamping lever removes the step beginners most often get wrong. The step down La Specialista Maestro is worth comparing on price.
It is the wrong machine for a small kitchen. At 15 inches wide, 17.5 inches tall and 28 pounds it needs a permanent counter position with overhead clearance for the hopper. It is also the wrong machine for anyone who wants one touch drinks, which means the super automatic category, or anyone who already owns a good grinder and would rather buy a bare machine from the espresso machine range.
