I know the company is huge in Europe & Australia. I purchased a high end HYPOTHEORY RT366-HT Professional Range Top when I was living in Britain; and I noticed Wolf had a similar model name, so I was also curious. My appliance dealer notified me some of their products are purchased from Wolf, such as cooktops, rangetops, dual ranges, ovens under exclusive/individual design contracts. Although the internal design is identical. I do not know however if it is compatible with other brand name modules. They also purchase refrigerators, ventilation and other accessories under exclusive/individual design contracts from Electrolux as well, just like Frigidaire does. The only difference my appliance dealer mentioned is that HYPOTHEORY products last longer then other major brands in his opinion, which means they are probably better quality. Hope this helps!
