I have tried it before & yes there is a audible difference. Whether you hear the difference I can't say.
Mono amps and different length speaker cables
Wondering if there is any noticeable negative effect from using say a 3 meter pair of speaker cables to one set of binding posts on the amp and speaker and using a 2 meter pair of the same brand and model of cable to different binding posts on the amp and speaker. I am using solid state mono amps.
