Vinyl and long cables or interconnects

Right now, my turntable and audio rack sits between and behind my speakers. I'm thinking of moving it. I could set up my monoblocs between the speakers and run long interconnects; or I could move the monoblocs too and use long speaker cables. Right now, I'm using cardas golden reference interconnects and speaker cables. For the best vinyl reproduction, would you use long speaker cables or interconnects? If I move the turntable out somewhere in front of the speakers and to the side, do you have any special placement recommendations? Favorite cables for long runs with vinyl? Thanks from sunny (for now) California. jeff
