For line-level balanced interconnections, ground-related factors that will act in the direction of reducing sensitivity to cable differences are:
(a) Pin 1 of the XLR connectors on each component (which is the pin that is used to connect the cable shield) is connected directly to chassis (i.e., via essentially zero ohms), and therefore presumably also to AC safety ground.
You may need a flashlight and a magnifying glass to be able to see the numbers adjacent to the pins of the XLR connectors.
(b) Circuit ground, which is presumably present on the ground shell of RCA connectors, is **not** connected directly to chassis/AC safety ground, but instead is connected to chassis/AC safety ground via a resistance of at least 10 ohms (and perhaps much more).
If and when you make these measurements, be sure that all interconnects are disconnected from the component being measured, or the results may be misleading.
