Matt, the oven I listed above has a "selectapower" membrane. The oven can do multi stage cooking such as defrosting frozen food on a low power level, warming it on a medium level, then finishing it on full power automatically with one programming sequence. All commercial microwaves have power levels except the very basic ones intended for front of house/self serve.
My question to you is, have you ever tried various commercial microwave ovens such as an Amana Menu Master, Pansonic NE, or Sharp Twin Touch or even a combination impingement oven?
These ovens don't just blast microwaves, but evenly distribute, reflect, attenuate, and blend them where multiple magnetrons are involved. There is tremendous finesse involved. There has to be in that the owner has to please and maximize the quality of the food involved not for one but for a minimum of thousands of customers. Nearly all commercial appliances are specifically engineered to maximize their intended goals- in the case of cooking appliances absolute congeniality- ie texture, flavor, evenness, appearance, color, ect. This concept entirely behind the success of restaurants and fast food corporations. They can take ingredients of any kind, even those of very low quality, and with the help of congeniality maximizing appliance produce very tasty results that would otherwise not be obtainable. Classic example, a commercial BUNN coffee maker can extract the full flavor of economy food service coffee grounds producing a smooth bitter free taste rivaling or exceeding organic/gourmet coffee in a residential drip machine that may produce a bitter/burnt taste on top of the rich flavor due to a lack of temperature control and poor water distribution capabilities.
How food is cooked depends just as much, if not more, than its quality or how it was made. The entire American economy was and is built upon maximizing the outcome of cost efficient materials. No commercial appliance maker will ever stay in business otherwise.
Try a Taylor clam shell grill, Taylor ice cream machine or a Henny Penny pressure fryer with some slightly above average ingredients and your perception of flavor will change forever.
