?OK to run 30 ft RCA from amp to preamp?


I am considering changing my set-up. Is it advisable to use 75 ohm, RG6 shielded cable with Canare DIY RCAs for a 30 ft run from preamp (BAT3i) to Primaluna 7 monos. Both are tube components. Speaker cables would be short, 2 meters. Are there any issues?

The system has developed "air" hiss/noise coming from the speakers. It is quite audible. I play mostly vinyl and I can hear it between tracks and between LPs. It seems to have increased over time. Could this be related to the interconnects I described above (although they are only 3 meters long)? Could it be tubes going bad?
Any help, advise is greatly appreciated as I am technically challenged.
Thanks!

I have a pair of Blue Jeans LC-1 cable running about 28 feet from my Aragon Stage One processor to Bel Canto M300 monoblocks, in and around AC, other components and other interconnects. No noise. My speaker cables are Speltz anti-cables running 3 feet to VR-4JRs. I suspect either the shielding is inadequate for the situation, or there is another source of noise.
