Many companies in high-end audio and elsewhere use a trickle-down approach to advance their products. The process begins with the development of a suite of new technologies, capabilities, components, or whatever the relevant entities might be. Typically, it's a flagship product that functions as the impetus, target, and first deployment of the new technologies. Subsequently, the new technologies trickle down to other models, each one incorporating a subset appropriate to its price point.
