This is “one” of the reasons monoblocks are made, to have very short speaker cables. Preferably 8’ or less. RCA should be 1M or less optimally, no more than 1.5-2M. Balanced XLRs can be run long.
How long should speaker cables be?
My cables are 12 feet long but with my current setup 6 feet would be more than enough. I recall reading somewhere that connectors should be short and speaker cables should be long. Does anyone have an opinion on this?
