It is going to be a primarily subjective evaluation based on ratings of in a carefully designed questionnaire by a panel experienced audiophiles and music lovers. We are going to evaluate different components in different circuits. Caps for example will be tested in signal de-coupling and X-over applications- everything in a elegantly simple circuits containing very few other passive components.
