If you really want to make a difference, forget about snake oil cables and use XLR instead of RCA. That is what the professionals do, and for a reason. See here for measurements: http://archimago.blogspot.nl/2017/06/measurements-oppo-sonica-dac-ess-sabre.html
Will it make a sonic difference in a domestic context with relatively short cable runs? I doubt it, but if you want the best, even if only observable on a scope, this is the way to go.
