System dependent in my experience.
Generally speaking I favor sticking with one brand/model on every component. Though with Purist Audio Design, you can sometimes get the absolute best performance by using different models within the Purist Line. As a for instance, you may want Venustas on speaker cables feeding low sensitivity speakers as they are a heavy gage and will allow lots of current without issue. The Corvus line is quite neutral and one may use it as an interconnect between source, Pre and amplifier along with Venustas for speakers and find phenomenal results.
