Best long low noise RCA cables


I have a 20 foot run between my preamp and 300b push pull amps. Using Blue Jean cables. If I simply lift them, or move them in the air, noise goes up or goes down etc.

Without spending ridiculous amounts of cash, I am looking for less noisy cables. Thank you for ideas.
