Stay with a single stereo set and use jumpers. Don’t use two pairs or a bi-wire set. Stay with quality copper cables and not silver or silver plated. Traditionally ProAcs are voiced more by ear than specs. I’d suggest looking at litz copper cables as that’s probably closer to what the internal wiring is. WyWires Platinum is where I’d start. Kimber 8TC would be another candidate but not going to have the openness of even WyWires Silver (not silver but copper) Series. Another crazy good cable for the money is Canare 4S11. The Canare takes a lot of hours to burn in but once it does it’s very neutral, with no edge at all and maybe a little on the softer side but not rolled off. Both the WyWyires and Canare do a better job of getting out of the way and not drawing attention to themselves as say the Kimber. The Kimber is still very good but not as open and has a little edge to it when compared to better cables. With ProAcs and quality components, stay with copper. If you want to experiment and not spend much try the Canare as it might be all you need... that being said, WyWires is more refined, more open and if your speakers have a hard time disappearing in your room they will help. Very organic cables that don’t smear, exaggerate or close things in. They simply breath.
