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.
This was quite a topic some threads ago. You may find it interesting if you can catch the thread before it falls in to the abyss. Good luck
One data point is my analysis on this subject at the Audio FAQ page at:


Depends entirely on the relative quality of your cables.
