Full loom of the same cable brand vs mixing and matching.

@kennymacc -

 As a matter of fact, I currently use three different brands of cables in my audio system with excellent results. 

                                                          DITTO:

        Synergistic Research for my Main, monoblock amps' interconnects,  PCs on Stealth XXX Purifier and Subwoofer amp (into outlet).

                                    Zu Mothers as PCs on everything else

                                 Kimber Kable interconnects on all sources.

                                                     Happy listening!
