Smodtactical,
You have tens of thousands of dollars of gear, do yourself a favor and replace the cheap RCA cables. Really good cables can be had for not a lot of money, look at: Morrow Audio (MA4), DHLabs Air Matrix, Zavfino Arcadia or Fusion, LavriCables Reference or Ultimate Silver, Cullen Cables Copper or Crossover, or Supra Trico or Supra EFF-ISL (found on eBay).....don't think a single cable is more than $300, and will be huge upgrades and more worthy of your equipment.
