Its connected between the two individual & isolated L & R channel cable screen braids, the screens are not connected to anything else, they are floating

I thought my RCA to DIN IC had the screen connect to signal earth at the DIN end.

In addition (since the RCA’s are the source end) the screen will also be connected to the ground via a padding resistor. The resistor is there to control the characteristic of the screen “seen” by the ground.

The overall screen in a cable is there to "protect the signal”. It has to have a connection to the system ground at some point, or it won’t work as needed. Note that system ground is not the same as mains earth, ideally they should be connected together at one point (usually at the most often used source), but in most cases a system will work without problems “floating” from (as in not connected to) mains earth. We would always recommend that a system has its system ground connected to mains earth for best sound quality.
