No Mentions of PC Triple C Wire, this wire has superseded other wire types used in my system, of which a large proportion was OCC.
Additionally Low Eddy Connections on both Cable and Chassis.
Try this on one channel and all other Channels will be the comparison, where I am feeling very confident will show you where the aspiration is to be found to have all channels altered to Low Eddy RCA - PC Triple C Wire as the Signal Path and maybe extend the usage of PC Triple C to within the Chassis Hook Up wiring.
If this is the route adopted you will not be the first to be thoroughly impressed.
