In most cases the Long IC with short speaker cables is the way to go.
Long IC/Short Speaker or Short IC/ Long Speaker
For monoblocks setup, would it it be better sonically to run long interconnects (from pre-amp to amp) and shorter speaker cables (from amp to speakers) or to run short interconnects and longer speaker cables? Does it make a difference? One thing I must note is that I can only run RCA connection IC. I do understand that the gain is more gain when using XLR IC. Thanks for your help.
