Length of speaker cables


I just went from 2 channel amp to mono blocks. Is it important that I stop using 4 meter audio quest rocket 88 and downsize to 6 ft? Will there be an audible improvement?

Went from Morrow 6’s to Cerious Graphene, like an upgraded component even without any breakin. Was a wow moment and all connections were and are cleaned and treated with stabilant.

Hi Steve 0713.  In general, speaker cables are more critical than interconnects. So, if you can, put the monoblocks very close to the speakers and use long interconnects to feed signal to them. You can easily make good interconnects using Belden microphone wire. You should hear a noticable improvement in addition to the serious improvement the new amps will make. Keep Smiling.
