Scott, in my view most of that commentary does apply only to dipoles rather than multipolar in-phase speakers such as the QSs. These appear to be a good compromise between "diffuseness" and "directness" and are easier to position and sound better on a wider variety of material than either dipoles or monopoles. As I and others have commented previously, if a musician or other sound is specifically located in a discrete surround channel(e.g. some pop SACDs and DVD-As)a monopole can locate that sound a bit more clearly. The majority of other sounds(including the ambience which is present in the classical CDs which I listen to)benefit from a more widely dispersed presentation which still sounds reasonably good on specifically located material.
